Could not getting enough sleep increase your risk of type 2 diabetes?

<p><em><a href="https://theconversation.com/profiles/giuliana-murfet-1517219">Giuliana Murfet</a>, <a href="https://theconversation.com/institutions/university-of-technology-sydney-936">University of Technology Sydney</a> and <a href="https://theconversation.com/profiles/shanshan-lin-1005236">ShanShan Lin</a>, <a href="https://theconversation.com/institutions/university-of-technology-sydney-936"><em>University of Technology Sydney</em></a></em></p> <p>Not getting enough sleep is a common affliction in the modern age. If you don’t always get as many hours of shut-eye as you’d like, perhaps you were concerned by news of a <a href="https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2815684">recent study</a> that found people who sleep less than six hours a night are at higher risk of type 2 diabetes.</p> <p>So what can we make of these findings? It turns out the relationship between sleep and diabetes is complex.</p> <h2>The study</h2> <p>Researchers analysed data from the <a href="https://www.ukbiobank.ac.uk/">UK Biobank</a>, a large biomedical database which serves as a global resource for health and medical research. They looked at information from 247,867 adults, following their health outcomes for more than a decade.</p> <p>The researchers wanted to understand the associations between sleep duration and type 2 diabetes, and whether a healthy diet reduced the effects of short sleep on diabetes risk.</p> <p>As part of their involvement in the UK Biobank, participants had been asked roughly how much sleep they get in 24 hours. Seven to eight hours was the average and considered normal sleep. Short sleep duration was broken up into three categories: mild (six hours), moderate (five hours) and extreme (three to four hours). The researchers analysed sleep data alongside information about people’s diets.</p> <p>Some 3.2% of participants were diagnosed with type 2 diabetes during the follow-up period. Although healthy eating habits were associated with a lower overall risk of diabetes, when people ate healthily but slept less than six hours a day, their risk of type 2 diabetes increased compared to people in the normal sleep category.</p> <p>The researchers found sleep duration of five hours was linked with a 16% higher risk of developing type 2 diabetes, while the risk for people who slept three to four hours was 41% higher, compared to people who slept seven to eight hours.</p> <p>One limitation is the study defined a healthy diet based on the number of servings of fruit, vegetables, red meat and fish a person consumed over a day or a week. In doing so, it didn’t consider how dietary patterns such as time-restricted eating or the Mediterranean diet may modify the risk of diabetes among those who slept less.</p> <p>Also, information on participants’ sleep quantity and diet was only captured at recruitment and may have changed over the course of the study. The authors acknowledge these limitations.</p> <h2>Why might short sleep increase diabetes risk?</h2> <p>In people with <a href="https://www.diabetesaustralia.com.au/about-diabetes/type-2-diabetes/">type 2 diabetes</a>, the body becomes resistant to the effects of a hormone called insulin, and slowly loses the capacity to produce enough of it in the pancreas. Insulin is important because it regulates glucose (sugar) in our blood that comes from the food we eat by helping move it to cells throughout the body.</p> <p>We don’t know the precise reasons why people who sleep less may be at higher risk of type 2 diabetes. But <a href="https://doi.org/10.7759/cureus.23501">previous research</a> has shown sleep-deprived people often have increased <a href="https://doi.org/10.1186/1476-511X-9-125">inflammatory markers</a> and <a href="https://doi.org/10.1007/s00125-015-3500-4">free fatty acids</a> in their blood, which <a href="https://doi.org/10.1007/s11892-018-1055-8">impair insulin sensitivity</a>, leading to <a href="https://doi.org/10.7759/cureus.23501">insulin resistance</a>. This means the body struggles to use insulin properly to regulate blood glucose levels, and therefore increases the risk of type 2 diabetes.</p> <p>Further, people who don’t sleep enough, as well as people who sleep in irregular patterns (such as shift workers), experience disruptions to their body’s natural rhythm, known as the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5995632/">circadian rhythm</a>.</p> <p>This can interfere with the release of hormones like <a href="https://doi.org/10.1210/edrv.18.5.0317">cortisol, glucagon and growth hormones</a>. These hormones are released through the day to meet the body’s changing energy needs, and normally keep blood glucose levels nicely balanced. If they’re compromised, this may reduce the body’s ability to handle glucose as the day progresses.</p> <p>These factors, and <a href="https://www.science.org/doi/10.1126/sciadv.aar8590">others</a>, may contribute to the increased risk of type 2 diabetes seen among people sleeping less than six hours.</p> <p>While this study primarily focused on people who sleep eight hours or less, it’s possible longer sleepers may also face an increased risk of type 2 diabetes.</p> <p>Research has previously shown a U-shaped correlation between sleep duration and type 2 diabetes risk. A <a href="https://doi.org/10.2337/dc14-2073">review</a> of multiple studies found getting between seven to eight hours of sleep daily was associated with the lowest risk. When people got less than seven hours sleep, or more than eight hours, the risk began to increase.</p> <p>The reason sleeping longer is associated with increased risk of type 2 diabetes may be linked to <a href="https://doi.org/10.2337/dc15-0186">weight gain</a>, which is also correlated with longer sleep. Likewise, people who don’t sleep enough are more likely to be <a href="https://doi.org/10.1016/j.sleh.2017.07.013">overweight or obese</a>.</p> <h2>Good sleep, healthy diet</h2> <p>Getting enough sleep is an important part of a healthy lifestyle and may reduce the risk of type 2 diabetes.</p> <p>Based on this study and other evidence, it seems that when it comes to diabetes risk, seven to eight hours of sleep may be the sweet spot. However, other factors could influence the relationship between sleep duration and diabetes risk, such as individual differences in sleep quality and lifestyle.</p> <p>While this study’s findings question whether a healthy diet can mitigate the effects of a lack of sleep on diabetes risk, a wide range of evidence points to the benefits of <a href="https://www.who.int/initiatives/behealthy/healthy-diet">healthy eating</a> for overall health.</p> <p>The <a href="https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2815684">authors of the study</a> acknowledge it’s not always possible to get enough sleep, and suggest doing <a href="https://pubmed.ncbi.nlm.nih.gov/33137489/">high-intensity interval exercise</a> during the day may offset some of the potential effects of short sleep on diabetes risk.</p> <p>In fact, exercise <a href="https://doi.org/10.1016/j.jshs.2023.03.001">at any intensity</a> can improve blood glucose levels.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/225179/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/giuliana-murfet-1517219">Giuliana Murfet</a>, Casual Academic, Faculty of Health, <a href="https://theconversation.com/institutions/university-of-technology-sydney-936">University of Technology Sydney</a> and <a href="https://theconversation.com/profiles/shanshan-lin-1005236">ShanShan Lin</a>, Senior Lecturer, School of Public Health, <a href="https://theconversation.com/institutions/university-of-technology-sydney-936">University of Technology Sydney</a></em></p> <p><em>Image credits: Getty Images</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

People in the world’s ‘blue zones’ live longer – their diet could hold the key to why

<p><em><a href="https://theconversation.com/profiles/justin-roberts-1176632">Justin Roberts</a>, <a href="https://theconversation.com/institutions/anglia-ruskin-university-1887">Anglia Ruskin University</a>; <a href="https://theconversation.com/profiles/joseph-lillis-1505087">Joseph Lillis</a>, <a href="https://theconversation.com/institutions/anglia-ruskin-university-1887">Anglia Ruskin University</a>, and <a href="https://theconversation.com/profiles/mark-cortnage-438941">Mark Cortnage</a>, <a href="https://theconversation.com/institutions/anglia-ruskin-university-1887">Anglia Ruskin University</a></em></p> <p>Ageing is an inevitable part of life, which may explain our <a href="https://time.com/4672969/why-do-people-want-to-live-so-long/">strong fascination</a> with the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2726954">quest for longevity</a>. The allure of <a href="https://pubmed.ncbi.nlm.nih.gov/26566891/">eternal youth</a> drives a <a href="https://www.alliedmarketresearch.com/longevity-and-anti-senescence-therapy-market-A14010">multi-billion pound industry</a> ranging from anti-ageing products, supplements and <a href="https://www.everydayhealth.com/diet-nutrition/longevity-diet">diets</a> for those hoping to extend their lifespan.</p> <p>f you look back to the turn of the 20th century, average life expectancy in the UK was around 46 years. Today, it’s closer to <a href="https://population.un.org/wpp/">82 years</a>. We are in fact <a href="https://pubmed.ncbi.nlm.nih.gov/27706136/">living longer than ever before</a>, possibly due to medical advancements and improved <a href="https://www.health.org.uk/publications/reports/mortality-and-life-expectancy-trends-in-the-uk">living and working conditions</a>.</p> <p>But living longer has also come at a price. We’re now seeing higher rates of <a href="https://www.who.int/data/gho/data/themes/mortality-and-global-health-estimates/ghe-leading-causes-of-death">chronic and degenerative diseases</a> – with heart disease consistently topping the list. So while we’re fascinated by what may help us live longer, maybe we should be more interested in being healthier for longer. Improving our “<a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4632858/">healthy life expectancy</a>” remains a global challenge.</p> <p>Interestingly, certain locations around the world have been discovered where there are a high proportion of centenarians who display remarkable physical and mental health. The <a href="https://pubmed.ncbi.nlm.nih.gov/15489066/">AKEA study of Sardinia, Italy</a>, as example, identified a “blue zone” (named because it was marked with blue pen), where there was a higher number of locals living in the central-eastern mountainous areas who had reached their 100th birthday compared with the wider Sardinian community.</p> <p>This longevity hotspot has since been expanded, and now includes several other areas around the world which also have greater numbers of longer-living, healthy people. Alongside Sardinia, these blue zones are now <a href="https://www.netflix.com/gb/title/81214929">popularly recognised</a> as: Ikaria, Greece; Okinawa, Japan; Nicoya, Costa Rica; and Loma Linda, California.</p> <p>Other than their long lifespans, people living in these zones also appear to share certain other commonalities, which centre around being <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3874460">part of a community</a>, having a <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4224996/">life purpose</a>, eating <a href="https://pubmed.ncbi.nlm.nih.gov/33514872/">nutritious, healthy foods</a>, keeping <a href="https://www.nature.com/articles/s41398-021-01735-7">stress levels</a> low and undertaking purposeful daily <a href="https://pubmed.ncbi.nlm.nih.gov/30202288/">exercise or physical tasks</a>.</p> <p>Their longevity could also relate to their <a href="https://pubmed.ncbi.nlm.nih.gov/9010380/">environment</a>, being mostly rural (or less polluted), or because of <a href="https://pubmed.ncbi.nlm.nih.gov/22253498/">specific longevity genes</a>.</p> <p>However, studies indicate genetics may only account for <a href="https://pubmed.ncbi.nlm.nih.gov/8786073">around 20-25% of longevity</a> – meaning a person’s lifespan is a complex interaction between lifestyle and genetic factors, which contribute to a long and healthy life.</p> <h2>Is the secret in our diet?</h2> <p>When it comes to diet, each blue zone has its own approach – so one specific food or nutrient does not explain the remarkable longevity observed. But interestingly, a diet rich in <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3662288">plant foods</a> (such as locally-grown vegetables, fruits and legumes) does appear to be reasonably consistent across these zones.</p> <p>For instance, the Seventh-day Adventists of Loma Linda are <a href="https://pubmed.ncbi.nlm.nih.gov/10641813/">predominately vegetarian</a>. For centenarians in Okinawa, <a href="https://pubmed.ncbi.nlm.nih.gov/20234038/">high intakes of flavonoids</a> (a chemical compound typically found in plants) from purple sweet potatoes, soy and vegetables, have been linked with <a href="https://pubmed.ncbi.nlm.nih.gov/11710359/">better cardiovascular health</a> – including lower cholesterol levels and lower incidences of stroke and heart disease.</p> <p>In Nicoya, consumption of locally produced rice and beans has been associated with <a href="https://pubmed.ncbi.nlm.nih.gov/34444746/">longer telomere length</a>. Telomeres are the structural part at the end of our chromosomes which protect our genetic material. Our telomeres get shorter each time a cell divides – so get progressively shorter as we age.</p> <p>Certain <a href="https://pubmed.ncbi.nlm.nih.gov/21102320/">lifestyle factors</a> (such as smoking and poor diet) can also shorten telomere length. It’s thought that telomere length acts as a <a href="https://pubmed.ncbi.nlm.nih.gov/31728493/">biomarker of ageing</a> – so having longer telomeres could, in part, be linked with longevity.</p> <p>But a plant-based diet isn’t the only secret. In Sardinia, for example, meat and fish is consumed in moderation in addition to locally grown vegetables and <a href="https://journalofethnicfoods.biomedcentral.com/articles/10.1186/s42779-022-00152-5">traditional foods</a> such as acorn breads, pane carasau (a sourdough flatbread), honey and soft cheeses.</p> <p>Also observed in several blue zone areas is the inclusion of <a href="https://www.jacc.org/doi/10.1016/j.jacc.2021.10.041">olive oil</a>, <a href="https://pubmed.ncbi.nlm.nih.gov/33669360/">wine</a> (in moderation – around 1-2 glasses a day), as well as <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3830687/">tea</a>. All of these contain powerful antioxidants which may help <a href="https://ncbi.nlm.nih.gov/pmc/articles/PMC10049696/">protect our cells</a> from damage <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6273542/">as we age</a>.</p> <p>Perhaps then, it’s a combination of the protective effects of various nutrients in the diets of these centenarians, which explains their exceptional longevity.</p> <p>Another striking observation from these longevity hot spots is that meals are typically <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7232892">freshly prepared at home</a>. Traditional blue zone diets also don’t appear to contain <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6538973/">ultra-processed foods</a>, fast foods or sugary drinks which may <a href="https://pubmed.ncbi.nlm.nih.gov/32330232/">accelerate ageing</a>. So maybe it’s just as important to consider what these longer-living populations are not doing, as much as what they are doing.</p> <p>There also appears to be a pattern of eating until 80% full (in other words partial <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9036399/">caloric reduction</a>. This could be important in also supporting how our cells deal with damage as we age, which could mean a longer life.</p> <p>Many of the factors making up these blue zone diets – primarily plant-based and natural whole foods – are associated with <a href="https://pubmed.ncbi.nlm.nih.gov/35706591/">lower risk of chronic diseases</a> such as <a href="https://pubmed.ncbi.nlm.nih.gov/28728684/">heart disease</a> and <a href="https://pubmed.ncbi.nlm.nih.gov/37589638/">cancer</a>. Not only could such diets contribute to a <a href="https://pubmed.ncbi.nlm.nih.gov/37836577/">longer, healthier life</a>, but could support a more <a href="https://pubmed.ncbi.nlm.nih.gov/33397404/">diverse gut microbiome</a>, which is also associated with healthy ageing.</p> <p>Perhaps then we can learn something from these remarkable centenarians. While diet is only one part of the bigger picture when it comes to longevity, it’s an area we can do something about. In fact, it might just be at the heart of improving not only the quality of our health, but the quality of how we age.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/221463/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/justin-roberts-1176632">Justin Roberts</a>, Professor of Nutritional Physiology, <a href="https://theconversation.com/institutions/anglia-ruskin-university-1887">Anglia Ruskin University</a>; <a href="https://theconversation.com/profiles/joseph-lillis-1505087">Joseph Lillis</a>, PhD Candidate in Nutritional Physiology, <a href="https://theconversation.com/institutions/anglia-ruskin-university-1887">Anglia Ruskin University</a>, and <a href="https://theconversation.com/profiles/mark-cortnage-438941">Mark Cortnage</a>, Senior Lecturer in Public Health and Nutrition, <a href="https://theconversation.com/institutions/anglia-ruskin-university-1887">Anglia Ruskin University</a></em></p> <p><em>Image credits: Getty Images </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Considering taking a weight-loss drug like Ozempic? Here are some potential risks and benefits

<p><a href="https://theconversation.com/profiles/lauren-ball-14718">Lauren Ball</a>, <em><a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a></em> and <a href="https://theconversation.com/profiles/emily-burch-438717">Emily Burch</a>, <em><a href="https://theconversation.com/institutions/southern-cross-university-1160">Southern Cross University</a></em></p> <p>After weight-loss drugs like Ozempic exploded onto the market, celebrities and social media influencers were quick to spruik their benefits, leading to their rapid rise in use. In the last three months of 2022, clinicians in the United States alone wrote <a href="https://www.washingtonpost.com/business/2023/09/27/ozempic-prescriptions-data-analysis/">more than nine million prescriptions</a> for these drugs.</p> <p>As they’ve grown in popularity, we’ve also heard more about the potential side effects – from common gastrointestinal discomforts, to more serious mental health concerns.</p> <p>But what does the science say about how well Ozempic and Wegovy (which are both brand names of the drug semaglutide) work for weight loss? And what are the potential side effects? Here’s what to consider if you or a loved one are thinking of taking the drug.</p> <h2>Potential benefits</h2> <p><strong>1) It’s likely to help you lose weight</strong></p> <p>The largest, well-conducted <a href="https://pubmed.ncbi.nlm.nih.gov/33567185/">research study</a> of semaglutide was from United Kingdom in 2021. Some 1,961 people who were classified as “overweight” or “obese” were randomly assigned to have either semaglutide or a placebo and followed for 68 weeks (about 1.3 years). All participants also had free access to advice about healthy eating and physical activity.</p> <p>The study found those taking semaglutide lost weight – significantly more than people who had the placebo (-14.9% of their body weight compared with -2.4% of body weight).</p> <p>In another <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9486455/">study</a> in the United States, one health-care clinic gave 408 people weekly injections of semaglutide. Over the first three months, those included in the final analysis (175 people) lost an average of 6.7kg. Over the first six months, they lost an average of 12.3kg.</p> <p>Large weight losses have been found in a more <a href="https://www.nature.com/articles/s41591-022-02026-4">recent trial</a> of semaglutide, suggesting weight loss is a very likely outcome of ongoing use of the medication.</p> <p><strong>2) It may reduce your chronic disease risk factors</strong></p> <p>When people in the overweight or obese weight categories lose <a href="https://www.sciencedirect.com/science/article/pii/S1550413116300535">at least 5%</a> of their body weight, physiological changes often occur beyond a change in weight or shape. This <a href="https://www.nih.gov/news-events/nih-research-matters/research-context-obesity-metabolic-health">might include</a> lowered cholesterol levels, lowered blood pressure and lowered blood glucose levels, which all reduce the risk of chronic diseases.</p> <p>In one of the semaglutide <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9486455/">trials</a>, most people (87.3%) lost at least 5% of their body weight. Although most of the large studies of semaglutide excluded people with metabolic health conditions such as type 2 diabetes, metabolic health gains were <a href="https://pubmed.ncbi.nlm.nih.gov/33567185/">observed</a>, including lowered blood pressure, blood glucose levels and fasting blood lipid (fat) levels.</p> <p>In the UK <a href="https://pubmed.ncbi.nlm.nih.gov/33567185/">study</a> from 2021, people taking semaglutide had greater improvements in physical capabilities and risk factors for heart disease and diabetes, including reductions in waist circumference, markers of inflammation, blood pressure and blood glucose levels.</p> <p><strong>3) It might improve your quality of life, emotional wellbeing or sense of achievement</strong></p> <p>The original trial of semaglutide did not focus on this bundle of benefits, but further follow-ups show additional benefits associated with the medication. Compared to the placebo, people taking semaglutide saw significant <a href="https://www.tandfonline.com/doi/full/10.1080/00325481.2022.2150006">improvements</a> in their physical functioning and perceptions of their general health, social functioning and mental health.</p> <p>Anecdotally (not based on scientific research), people using semaglutide, such as <a href="https://people.com/oprah-winfrey-reveals-weight-loss-medication-exclusive-8414552">Oprah Winfrey</a>, report a reclaiming or turning point of their life, social situation and body image.</p> <h2>What about the risks?</h2> <p><strong>1) You may experience gastrointestinal symptoms</strong></p> <p>In the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9486455/">US clinical trial</a>, nearly half (48.6%) of people taking semaglutide reported experiencing adverse effects. Nausea and vomiting were the most frequently experienced (36.6%) followed by diarrhea (8.6%), fatigue (6.3%) and constipation (5.7%).</p> <p>In the UK study, nausea and diarrhoea were also commonly reported.</p> <p>In <a href="https://www.nejm.org/doi/10.1056/NEJMoa2032183?url_ver=Z39.88-2003&amp;rfr_id=ori:rid:crossref.org&amp;rfr_dat=cr_pub%20%200pubmed">another trial</a>, many participants (74.2%) using semaglutide reported gastrointestinal symptoms. However, nearly half (47.9%) using the placebo also reported gastrointestinal symptoms, indicating that symptoms may be similar to those experienced during normal daily living.</p> <p>Most gastrointestinal symptoms were mild to moderate in severity, and resolved for most people without the need to stop participating in the study.</p> <p><strong>2) You might feel fatigued</strong></p> <p>Fatigue was the second most common side effect for participants in the US <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9486455/">clinical trial</a>, affecting 6.3% of participants.</p> <p><strong>3) You might be among the minority who don’t tolerate the drug</strong></p> <p>Australia’s Therapeutic Goods Administration (TGA) has <a href="https://www.tga.gov.au/news/safety-alerts/compounding-safety-information-semaglutide-products">approved</a> Ozempic as safe to use, for the treatment of type 2 diabetes but it has not yet been approved for weight loss. The TGA has also <a href="https://www.tga.gov.au/resources/prescription-medicines-registrations/wegovy-novo-nordisk-pharmaceuticals-pty-ltd">approved Wegovy</a> (a higher dose of semagtlutide) for weight loss, however it’s not yet available in Australia.</p> <p>In the US <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9486455/">clinical trial</a>, no unexpected safety issues were reported. However, five patients (2.9%) had to stop taking the medication because they could not tolerate the adverse effects. Fifteen (8.6%) had to either reduce the dose or remain on the same dose to avoid the adverse effects.</p> <p>In <a href="https://www.nejm.org/doi/10.1056/NEJMoa2032183?url_ver=Z39.88-2003&amp;rfr_id=ori:rid:crossref.org&amp;rfr_dat=cr_pub%20%200pubmed">other studies</a>, some patients stopped the trial due to gastrointestinal symptoms being so severe they could not tolerate continuing.</p> <p>More severe safety concerns reported in <a href="https://www.nejm.org/doi/10.1056/NEJMoa2032183?url_ver=Z39.88-2003&amp;rfr_id=ori:rid:crossref.org&amp;rfr_dat=cr_pub%20%200pubmed">studies</a> include gallbladder-related disorders (mostly cholelithiasis, also known as gallstones) in 34 patients (2.6%) and mild acute pancreatitis in three patients (0.2%). All people recovered during the trial period.</p> <p>A 2024 European <a href="https://link.springer.com/article/10.1007/s11096-023-01694-7">study</a> analysed psychiatric adverse events associated with semaglutide, liraglutide and tirzepatide (which work in a similar way to semaglutide). Between January 2021 and May 2023, the drug database recorded 481 psychiatric events (about 1.2% of the total reported) associated with these drugs. About half of these events were reported as depression, followed by anxiety (39%) and suicidal ideation (19.6%).

Eating some chocolate really might be good for you – here’s what the research says

<p><em><a href="https://theconversation.com/profiles/dan-baumgardt-1451396">Dan Baumgardt</a>, <a href="https://theconversation.com/institutions/university-of-bristol-1211">University of Bristol</a></em></p> <p>Although it always makes me scoff slightly to see Easter eggs making their first appearance in supermarkets at the end of December, there are few people who aren’t delighted to receive a bit of chocolate every year.</p> <p>It makes sense that too much chocolate would be bad for you because of the high fat and sugar content in most products. But what should we make of common claims that eating some chocolate is actually good for you?</p> <p>Happily, there is a fair amount of evidence that shows, in the right circumstances, chocolate may be both beneficial for your heart and good for your mental state.</p> <p>In fact, chocolate – or more specifically cacao, the raw, unrefined bean – is a medicinal wonder. It contains many different active compounds which can evoke pharmacological effects within the body, like medicines or drugs.</p> <p>Compounds that lead to neurological effects in the brain have to be able to cross the <a href="https://link.springer.com/chapter/10.1007/978-3-642-13443-2_7">blood-brain barrier</a>, the protective shield which prevents harmful substances – like toxins and bacteria – entering the delicate nervous tissue.</p> <p>One of these is the compound <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3672386/">theobromine</a>, which is also found in tea and contributes towards its bitter taste. Tea and chocolate also contain caffeine, which theobromine is related to as part of the purine family of chemicals.</p> <p>These chemicals, among others, contribute to chocolate’s addictive nature. They have the ability to cross the blood-brain barrier, where they can influence the nervous system. They are therefore known as <a href="https://pubmed.ncbi.nlm.nih.gov/15549276/">psychoactive</a> chemicals.</p> <figure><iframe src="https://www.youtube.com/embed/HloqayQdR6M?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <p>What effects can chocolate have on mood? Well, <a href="https://academic.oup.com/nutritionreviews/article/71/10/665/1931144?login=false">a systematic review</a> looked at a group of studies which examined the feelings and emotions associated with consuming chocolate. Most demonstrated improvements in mood, anxiety, energy and states of arousal.</p> <p>Some noted the feeling of guilt, which is perhaps something we’ve all felt after one too many Dairy Milks.</p> <h2>Health benefits of cocoa</h2> <p>There are other organs, aside from the brain, that might benefit from the medicinal effects of cocoa. For centuries, chocolate has been used as a medicine to treat a <a href="https://pubmed.ncbi.nlm.nih.gov/10917925/">long list of diseases</a> including anaemia, tuberculosis, gout and even low libido.</p> <p>These might be spurious claims but there is evidence to suggest that eating cacao has a positive effect on the cardiovascular system. First, it can prevent <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8068178/">endothelial dysfunction</a>. This is the process through which arteries harden and get laden down with fatty plaques, which can in turn lead to heart attacks and strokes.</p> <p>Eating dark chocolate may also reduce <a href="https://www.sciencedirect.com/science/article/pii/S1537189115001135?via%3Dihub">blood pressure</a>, which is another risk factor for developing arterial disease, and prevent formation of clots which block up blood vessels.</p> <figure><iframe src="https://www.youtube.com/embed/8VUcPCbSSCY?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <p>Some studies have suggested that dark chocolate might be useful in adjusting ratios of <a href="https://pubmed.ncbi.nlm.nih.gov/20968113/">high-density lipoprotein cholesterol</a>, which can help protect the heart.</p> <p>Others have examined insulin resistance, the phenomenon associated with Type 2 diabetes and weight gain. They suggest that the <a href="https://www.sciencedirect.com/science/article/pii/S0963996900000697#:%7E:text=Cocoa%20is%20rich%20in%20polyphenols%20particularly%20in%20catechins,and%20cocoa%20powder%20have%20been%20published%20only%20recently.">polyphenols</a> – chemical compounds present in plants – found in foodstuffs like chocolate may also lead to <a href="https://pubmed.ncbi.nlm.nih.gov/29993262/">improved control of blood sugars</a>.</p> <h2>Chocolate toxicity</h2> <p>As much as chocolate might be considered a medicine for some, it can be a poison for others.</p> <p>It’s well documented that the ingestion of caffeine and theobromine is highly toxic for domestic animals. Dogs are <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4801869/">particularly affected</a> because of their often voracious appetites and generally unfussy natures.</p> <p>The culprit is often dark chocolate, which can provoke symptoms of agitation, rigid muscles and even seizures. In certain cases, if ingested in high enough quantities, it can lead to comas and abnormal, even fatal heart rhythms.</p> <p>Some of the compounds found in chocolate have also been found to have potentially negative effects in humans. Chocolate is a source of oxalate which, along with calcium, is one of the main components of <a href="https://pubmed.ncbi.nlm.nih.gov/20301742/">kidney stones</a>.</p> <p>Some clinical groups have advised against consuming oxalate rich foods, such as spinach and rhubarb – and chocolate, for those who suffer from recurrent kidney stones.</p> <p>So, what should all this mean for our chocolate consumption habits? Science points in the direction of chocolate that has as high a cocoa solid content as possible, and the minimum of extras. The potentially harmful effects of chocolate are more related to fat and sugar, and may counteract any possible benefits.</p> <p>A daily dose of 20g-30g of plain or dark chocolate with cocoa solids above 70% – rather than milk chocolate, which contains fewer solids and white chocolate, which contains none – could lead to a greater health benefit, as well as a greater high.</p> <p>But whatever chocolate you go for, please don’t share it with the dog.<!-- Below is The Conversation's page counter tag.

Here’s why having chocolate can make you feel great or a bit sick – plus 4 tips for better eating

<p><em><a href="https://theconversation.com/profiles/saman-khalesi-366871">Saman Khalesi</a>, <a href="https://theconversation.com/institutions/cquniversity-australia-2140">CQUniversity Australia</a></em></p> <p>Australians are <a href="https://www.retail.org.au/media/sweet-spending-boon-predicted-for-easter-retail">predicted</a> to spend around A$1.7 billion on chocolates, hot cross buns and other special foods this Easter season.</p> <p>Chocolate has a long history of production and consumption. It is made from cacao beans that go through processes including fermentation, drying, roasting and grounding. What is left is a rich and fatty liquor that is pressed to remove the fat (cocoa butter) and the cacao (or “cocoa”) powder which will then be mixed with different ingredients to produce dark, milk, white and other types of chocolates.</p> <p>There are several health benefits and potential problems that come in these sweet chocolatey packages.</p> <h2>The good news</h2> <p>Cacao beans contain <a href="https://foodstruct.com/food/cocoa-bean">minerals</a> like iron, potassium, magnesium, zinc and phosphorus and some vitamins. They are also rich in beneficial chemicals called <a href="https://pubmed.ncbi.nlm.nih.gov/23150750/">polyphenols</a>.</p> <p>These are great antioxidants, with the potential to <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5465250/">improve heart health</a>, increase <a href="https://pubmed.ncbi.nlm.nih.gov/25164923/">nitric oxide</a> (which dilates blood vessels) and <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3488419/">reduce blood pressure</a>, provide food for gut microbiota and <a href="https://www.mdpi.com/2072-6643/12/7/1908">promote gut health</a>, boost the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5465250/">immune system</a> and reduce inflammation.</p> <p>However, the concentration of polyphenols in the chocolate we eat depends largely on the cocoa solid amounts used in the final product.</p> <p>In general terms, the darker the chocolate, the more cocoa solids, minerals and polyphenols it has. For example, dark chocolates may have around <a href="https://www.tandfonline.com/doi/full/10.1080/10942912.2011.614984">seven times more polyphenols</a> compared to white chocolates and <a href="https://www.tandfonline.com/doi/full/10.1080/10942912.2011.614984">three times more polyphenols</a> compared to milk chocolates.</p> <h2>But also some bad news</h2> <p>Unfortunately, the <a href="https://theconversation.com/treat-or-treatment-chocolate-is-good-but-cocoa-is-better-for-your-heart-3084">health benefits of cocoa solids</a> are easily offset by the high sugar and fat content of modern-day chocolates. For example, milk and white chocolate eggs are on average 50% sugar, 40% fat (mostly saturated fats) – which means a lot of added kilojoules (calories).</p> <p>Also, there may be some side effects that come with ingesting chocolate.</p> <p>Cocoa beans include a compound called theobromine. While it has the anti-inflammatory properties responsible for some of the health benefits of chocolate, it is also a mild brain stimulant that acts in a similar way to caffeine. The mood boost it offers may also be partly responsible for how much we <a href="https://www.frontiersin.org/articles/10.3389/fphar.2015.00030/full?crsi=662496658&amp;cicada_org_src=healthwebmagazine.com&amp;cicada_org_mdm=direct">like chocolate</a>. Dark chocolate has higher theobromine compared to milk and white chocolate.</p> <p>But accordingly, overindulging in chocolate (and therefore theobromine) may lead to feeling restless, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3672386/">headaches</a> and nausea.</p> <h2>What else is in your chocolate?</h2> <p>Milk and dairy-based chocolates may also cause stomach upset, abdominal pain and bloating in people with <a href="https://dietitiansaustralia.org.au/health-advice/lactose-intolerance">lactose intolerance</a>. This happens when we don’t produce enough lactase enzymes to digest milk sugar (lactose).</p> <p>People with lactose intolerance can usually tolerate up to 6 grams of lactose without showing symptoms. Milk chocolate can have around <a href="https://www.ncbi.nlm.nih.gov/books/NBK310258/">3 grams of lactose</a> per 40 grams (the size of a standard chocolate bar). So two chocolate bars (or the equivalent in milk chocolate eggs or bunnies) may be enough to cause symptoms.</p> <p>It’s worth noting that lactase enzyme activity dramatically declines as we age, with the highest activity in newborns and children. So lactose sensitivity or intolerance may not be such an issue for your kids and your symptoms may increase over time. Genetics also plays a major role in how sensitive people are to lactose.</p> <p><a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6815241/">Allergic reactions</a> to chocolate are usually due to the added ingredients or cross-contamination with potential allergens such as nuts, milk, soy, and some sweeteners used in the production of chocolate.</p> <p>Symptoms can be mild (acne, rashes and stomach pain) or more severe (swelling of the throat and tongue and shortness of breath).</p> <p>If you or your family members have known allergic reactions, make sure you read the label before indulging – especially in a whole block or basket of the stuff. And if you or your family members do experience symptoms of an allergic reaction after eating chocolate, <a href="https://www.betterhealth.vic.gov.au/health/conditionsandtreatments/allergic-reactions-emergency-first-aid">seek medical attention</a> immediately.</p> <h2>4 take home tips</h2> <p>So, if you are like me and have a weakness for chocolate there are a few things you can do to make the experience a good one.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/202848/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <ol> <li>keep an eye out for the darker chocolate varieties with higher cocoa solids. You may notice a percentage on labelling, which refers to how much of its weight is from cocoa beans. In general, the higher this percentage, the lower the sugar. White chocolate has almost no cocoa solid, and mostly cocoa butter, sugar and other ingredients. Dark chocolate has 50–100% cocoa beans, and less sugar. Aim for at least 70% cocoa</li> <li>read the fine print for additives and possible cross-contamination, especially if allergies might be an issue</li> <li>the ingredients list and nutrition information panel should tell you all about the chocolate you choosing. Go for varieties with lower sugar and less saturated fat. Nuts, seeds and dried fruits are better ingredients to have in your chocolate than sugar, creme, syrup, and caramel</li> <li>finally, treat yourself – but keep the amount you have within sensible limits!</li> </ol> <p><em><a href="https://theconversation.com/profiles/saman-khalesi-366871">Saman Khalesi</a>, Postdoctoral Fellow of the National Heart Foundation &amp; Senior Lecturer and Discipline Lead in Nutrition, School of Health, Medical and Applied Sciences, <a href="https://theconversation.com/institutions/cquniversity-australia-2140">CQUniversity Australia</a></em></p> <p><em>Image credits: Getty Images</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

How bad is junk food for you, really?

<p>Consuming more junk foods, such as soft drinks, packaged snacks, and sugary cereals, is associated with a higher risk of more than 30 different health problems – both physical and mental – according to researchers.</p> <p>A study, known as an umbrella review, combined the results of 45 previous meta-analyses published in the last three years, representing about 10 million participants.</p> <p>Thirty-two different poor health outcomes were found to be linked to the consumption of ultra-processed foods (UPFs), with varying levels of evidence supporting the findings.</p> <p>The researchers found the most convincing evidence around higher ultra-processed food intake, which was associated with a 50% increased risk of cardiovascular disease-related death, a 48-53% higher risk of anxiety and common mental disorders, and a 12% greater risk of type 2 diabetes.</p> <p>Evidence marked as ‘highly suggestive’ included a 21% increase in death from any cause, a 40-66% increased risk of a heart disease related death, obesity, type 2 diabetes, and sleep problems, as well as a 22% increased risk of depression.</p> <p>The review also found there may be links between ultra-processed food and asthma; gastrointestinal health; some cancers; and other risk factors such as high blood fats and low levels of ‘good’ cholesterol, but the researchers note this evidence is limited.</p> <p>Dr Daisy Coyle from the George Institute for Global Health in Sydney, who was not involved in the research, says the statistics are “staggering.”</p> <p>“Ultra-processed foods, laden with additives and sometimes lacking in essential nutrients, have become ubiquitous in the Australian diet,” she says.</p> <p>“In fact, they make up almost half of what we buy at the supermarket. While not all ultra-processed foods are linked to poor health outcomes, many are, particularly sugary drinks and processed meats.”</p> <div> </div> <p>While the findings are in line with other research that highlights the health risks associated with UPFs, some experts have pointed out that the study is observational, and therefore can’t prove the ultra-processed foods cause these health issues. It can only show an association.</p> <p>“While these associations are interesting and warrant further high-quality research, they do not and cannot provide evidence of causality,” The University of Sydney’s Dr Alan Barclay told the AusSMC.</p> <p>“By their very nature, observational studies are renowned for being confounded by numerous factors – both known and unknown.”</p> <p>Clare Collins, Laureate Professor at the University of Newcastle agreed, but added that it’s difficult to conduct dietary studies like this in a different way.</p> <p>“The studies are observational, which means cause and effect cannot be proven and that the research evidence gets downgraded, compared to intervention studies,” she says.</p> <p>“The problem is that it is not ethical to do an intervention study lasting for many years where you feed people lots of UPF every day and wait for them to get sick and die.”</p> <p>For now, researchers seem to agree that it can’t be a bad thing to minimise UPF intake.</p> <p>The review suggests a need for policies that pull consumers away from ultra-processed foods, such as advertising restrictions, warning labels, bans in schools and hospitals. It also calls for measures that make healthier foods more accessible and affordable.</p> <p>Dr Charlotte Gupta from Central Queensland University suggests that this is issue of accessibility is particularly relevant for shift workers such as doctors, nurses, firefighters, taxi drivers, miners, and hospitality workers.</p> <p>“There is a lack of availability of fresh foods or time to prepare any food, and so ultra-processed foods have to be relied on (e.g. from the vending machine in the hospital),” she said.</p> <p>“This highlights the need for not only individuals to try reducing ultra-processed foods in our diet, but also for public health actions to improve access to healthier foods.”</p> <p><em>Image credits: Shutterstock</em></p> <p><em><a href="https://cosmosmagazine.com/health/how-bad-is-junk-food-for-you-really/">This article</a> was originally published on <a href="https://cosmosmagazine.com">Cosmos Magazine</a> and was written by <a href="https://cosmosmagazine.com/contributor/olivia-henry/">Olivia Henry</a>. </em></p>

Restaurant sparks outrage for "ridiculous" fee

<p>As inflation rates continue to rise it is not surprising that restaurants are charging extra fees, but one disgruntled customer was particularly shocked to see this "ridiculous" fee on their bill. </p> <p>The customer, who dined at restaurant and cocktail bar in Georgia, USA shamed the restaurant for charging their customers a $20 fee for “live band entertainment”.</p> <p>They shared their complaints on Reddit with a copy of their receipt and an unexpected fee at the bottom which read: “Two Live Band Entertainment Fee — $20”.</p> <p>Most people in the comments were equally annoyed and called the fee "ridiculous". </p> <p>“This is one of those leave money on the table, hand the waiter a tip and leave, sorry but if I didn’t order it, I’m not paying for it,” one wrote. </p> <p>“Great way to not have repeat customers,” said another.</p> <p>“This will backfire for them, just be honest and upfront," a third added. </p> <p>Other commenters were less sympathetic and did not understand why the customer was complaining when it looked like they could afford it. </p> <p>“When you’re paying seven dollars for a bottle of water, you really don’t get to complain about ‘unexpected costs.’ You knew what you signed up for," one commenter wrote. </p> <p>“Imagine a live band getting paid, huh,” another added. </p> <p>“They’re buying $7 bottles of water, they can probably afford it,” added a third.</p> <p><em>Image: Getty/ Reddit</em></p>

I want to eat healthily. So why do I crave sugar, salt and carbs?

<p><em><a href="https://theconversation.com/profiles/hayley-oneill-1458016">Hayley O'Neill</a>, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a></em></p> <p>We all want to eat healthily, especially as we reset our health goals at the start of a new year. But sometimes these plans are sabotaged by powerful cravings for sweet, salty or carb-heavy foods.</p> <p>So why do you crave these foods when you’re trying to improve your diet or lose weight? And what can you do about it?</p> <p>There are many reasons for craving specific foods, but let’s focus on four common ones:</p> <h2>1. Blood sugar crashes</h2> <p>Sugar is a key energy source for all animals, and its taste is one of the most basic sensory experiences. Even without specific sweet taste receptors on the tongue, a strong preference for sugar can develop, indicating a mechanism beyond taste alone.</p> <p>Neurons <a href="https://www.nature.com/articles/s41593-021-00982-7">responding to sugar</a> are activated when sugar is delivered to the gut. This can increase appetite and make you want to consume more. Giving into cravings also drives an appetite for more sugar.</p> <p>In the long term, research suggests a high-sugar diet can affect <a href="https://www.bmj.com/content/369/bmj.m2382">mood</a>, digestion and <a href="https://pubmed.ncbi.nlm.nih.gov/33339337/">inflammation</a> in the <a href="https://www.science.org/doi/10.1126/scitranslmed.aay6218?url_ver=Z39.88-2003&amp;rfr_id=ori:rid:crossref.org&amp;rfr_dat=cr_pub%20%200pubmed">gut</a>.</p> <p>While there’s a lot of <a href="https://www.sciencedirect.com/science/article/pii/S0149763402000040?via%3Dihub#aep-section-id23">variation between individuals</a>, regularly eating sugary and high-carb foods can lead to <a href="https://pubmed.ncbi.nlm.nih.gov/30951762/">rapid spikes and crashes</a> in blood sugar levels. When your blood sugar drops, your body can respond by craving quick sources of energy, often in the form of sugar and carbs because these deliver the fastest, most easily accessible form of energy.</p> <h2>2. Drops in dopamine and serotonin</h2> <p>Certain neurotransmitters, such as <a href="https://pubmed.ncbi.nlm.nih.gov/30595479/">dopamine</a>, are involved in the reward and pleasure centres of the brain. Eating sugary and carb-rich foods can trigger the release of dopamine, creating a pleasurable experience and reinforcing the craving.</p> <p>Serotonin, the feel-good hormone, suppresses <a href="https://www.sciencedirect.com/science/article/pii/S1569733910700886">appetite</a>. Natural changes in serotonin can influence daily fluctuations in mood, energy levels and attention. It’s also associated with eating more <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5829131/">carb-rich snacks in the afternoon</a>.</p> <p><a href="https://pubmed.ncbi.nlm.nih.gov/21985780/">Low carb diets</a> may reduce serotonin and lower mood. However, a recent systematic review suggests little association between these diets and risk for <a href="https://www.sciencedirect.com/science/article/pii/S0165032722013933?via%3Dihub">anxiety and depression</a>.</p> <p>Compared to men, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4189179/">women tend to crave more carb rich foods</a>. Feeling irritable, tired, depressed or experiencing carb cravings are part of premenstrual <a href="https://pubmed.ncbi.nlm.nih.gov/29218451/">symptoms</a> and could be <a href="https://www.ncbi.nlm.nih.gov/books/NBK560698/">linked to</a> reduced <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9928757/">serotonin levels</a>.</p> <h2>3. Loss of fluids and drops in blood sugar and salt</h2> <p>Sometimes our bodies crave the things they’re missing, such as hydration or even salt. A low-carb diet, for example, <a href="https://www.ncbi.nlm.nih.gov/books/NBK537084/">depletes</a> insulin levels, decreasing sodium and water retention.</p> <p><a href="https://www.sciencedirect.com/science/article/pii/S1933287419302673">Very low-carb diets</a>, like ketogenic diets, induce “ketosis”, a metabolic state where the body switches to using fat as its primary energy source, moving away from the usual dependence on carbohydrates.</p> <p>Ketosis is often associated with increased urine production, further contributing to potential fluid loss, electrolyte imbalances and salt cravings.</p> <h2>4. High levels of stress or emotional turmoil</h2> <p><a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4214609/">Stress</a>, boredom and emotional turmoil can lead to cravings for comfort foods. This is because stress-related hormones can impact our appetite, satiety (feeling full) and food preferences.</p> <p>The stress hormone <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3425607/">cortisol</a>, in particular, can drive cravings for <a href="https://www.sciencedirect.com/science/article/abs/pii/S0306453000000354">sweet comfort foods</a>.</p> <p>A <a href="https://www.sciencedirect.com/science/article/abs/pii/S0306453000000354">2001 study</a> of 59 premenopausal women subjected to stress revealed that the stress led to higher calorie consumption.</p> <p><a href="https://pubmed.ncbi.nlm.nih.gov/37295418/">A more recent study</a> found chronic stress, when paired with high-calorie diet, increases food intake and a preference for sweet foods. This shows the importance of a healthy diet during stress to prevent weight gain.</p> <h2>What can you do about cravings?</h2> <p>Here are four tips to curb cravings:</p> <p><strong>1) don’t cut out whole food groups.</strong> Aim for a well-balanced diet and make sure you include:</p> <ul> <li> <p><em>sufficient protein</em> in your meals to help you feel full and reduce the urge to snack on sugary and carb-rich foods. Older adults should aim for 20–40g protein per meal with a particular focus on <a href="https://onlinelibrary.wiley.com/doi/epdf/10.1111/jhn.12838">breakfast and lunch</a> and an overall daily protein intake of at least <a href="https://apps.who.int/iris/handle/10665/43411">0.8g</a> per kg of body weight for <a href="https://pubmed.ncbi.nlm.nih.gov/35187864/">muscle health</a></p> </li> <li> <p><em>fibre-rich foods</em>, such as vegetables and whole grains. These make you feel full and <a href="https://pubmed.ncbi.nlm.nih.gov/32142510/">stabilise your blood sugar</a> levels. Examples include broccoli, quinoa, brown rice, oats, beans, lentils and bran cereals. Substitute refined carbs high in sugar like processed snack bars, soft drink or baked goods for more complex ones like whole grain bread or wholewheat muffins, or nut and seed bars or energy bites made with chia seeds and oats</p> </li> </ul> <p><strong>2) manage your stress levels.</strong> Practise stress-reduction techniques like meditation, deep breathing, or yoga to manage emotional triggers for cravings. Practising <a href="https://pubmed.ncbi.nlm.nih.gov/30570305/">mindful eating</a>, by eating slowly and tuning into bodily sensations, can also reduce daily calorie intake and curb cravings and stress-driven eating</p> <p><strong>3) get enough sleep.</strong> Aim for <a href="https://pubmed.ncbi.nlm.nih.gov/33054337/">seven to eight</a> hours of quality sleep per night, with a minimum of seven hours. <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9031614/">Lack of sleep</a> can disrupt hormones that regulate hunger and cravings</p> <p><strong>4) control your portions.</strong> If you decide to indulge in a treat, control your portion size to avoid overindulging.</p> <p>Overcoming cravings for sugar, salt and carbs when trying to eat healthily or lose weight is undoubtedly a formidable challenge. Remember, it’s a journey, and setbacks may occur. Be patient with yourself – your success is not defined by occasional cravings but by your ability to manage and overcome them.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/212114/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/hayley-oneill-1458016">Hayley O'Neill</a>, Assistant Professor, Faculty of Health Sciences and Medicine, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a></em></p> <p><em>Image credits: Getty Images </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

We looked at 700 plant-based foods to see how healthy they really are. Here’s what we found

<p><em><a href="https://theconversation.com/profiles/laura-marchese-1271636">Laura Marchese</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a> and <a href="https://theconversation.com/profiles/katherine-livingstone-324808">Katherine Livingstone</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a></em></p> <p>If you’re thinking about buying plant-based foods, a trip to the supermarket can leave you bewildered.</p> <p>There are plant-based burgers, sausages and mince. The fridges are loaded with non-dairy milk, cheese and yoghurt. Then there are the tins of beans and packets of tofu.</p> <p>But how much is actually healthy?</p> <p>Our nutritional audit of more than 700 plant-based foods for sale in Australian supermarkets has just been <a href="https://www.sciencedirect.com/science/article/pii/S0889157524000516">published</a>. We found some products are so high in salt or saturated fat, we’d struggle to call them “healthy”.</p> <h2>We took (several) trips to the supermarket</h2> <p>In 2022, we visited two of each of four major supermarket retailers across Melbourne to collect information on the available range of plant-based alternatives to meat and dairy products.</p> <p>We took pictures of the products and their nutrition labels.</p> <p>We then analysed the nutrition information on the packaging of more than 700 of these products. This included 236 meat substitutes, 169 legumes and pulses, 50 baked beans, 157 dairy milk substitutes, 52 cheese substitutes and 40 non-dairy yoghurts.</p> <h2>Plant-based meats were surprisingly salty</h2> <p>We found a wide range of plant-based meats for sale. So, it’s not surprising we found large variations in their nutrition content.</p> <p>Sodium, found in added salt and which contributes to <a href="https://www.heartfoundation.org.au/bundles/healthy-living-and-eating/salt-and-heart-health">high blood pressure</a>, was our greatest concern.</p> <p>The sodium content varied from 1 milligram per 100 grams in products such as tofu, to 2,000mg per 100g in items such as plant-based mince products.</p> <p>This means we could eat our entire <a href="https://www.betterhealth.vic.gov.au/health/healthyliving/salt">daily recommended sodium intake</a> in just one bowl of plant-based mince.</p> <p>An <a href="https://www.tandfonline.com/doi/full/10.1080/09637486.2022.2137786">audit</a> of 66 plant-based meat products in Australian supermarkets conducted in 2014 found sodium ranged from 316mg in legume-based products to 640mg in tofu products, per 100g. In a <a href="https://www.mdpi.com/2072-6643/11/11/2603">2019 audit</a> of 137 products, the range was up to 1,200mg per 100g.</p> <p>In other words, the results of our audit seems to show a consistent trend of plant-based meats <a href="https://www.tandfonline.com/doi/full/10.1080/09637486.2022.2137786">getting saltier</a>.</p> <h2>What about plant-based milks?</h2> <p>Some 70% of the plant-based milks we audited were fortified with calcium, a nutrient important for <a href="https://www.betterhealth.vic.gov.au/health/healthyliving/calcium">bone health</a>.</p> <p>This is good news as a <a href="https://www.mdpi.com/2072-6643/12/5/1254">2019-2020 audit</a> of 115 plant-based milks from Melbourne and Sydney found only 43% of plant-based milks were fortified with calcium.</p> <p>Of the fortified milks in our audit, almost three-quarters (73%) contained the <a href="https://www.eatforhealth.gov.au/food-essentials/five-food-groups/milk-yoghurt-cheese-andor-their-alternatives-mostly-reduced-fat">recommended amount of calcium</a> – at least 100mg per 100mL.</p> <p>We also looked at the saturated fat content of plant-based milks.</p> <p>Coconut-based milks had on average up to six times higher saturated fat content than almond, oat or soy milks.</p> <p><a href="https://www.mdpi.com/2072-6643/12/5/1254">Previous audits</a> also found coconut-based milks were much higher in saturated fat than all other categories of milks.</p> <h2>A first look at cheese and yoghurt alternatives</h2> <p>Our audit is the first study to identify the range of cheese and yoghurt alternatives available in Australian supermarkets.</p> <p>Calcium was only labelled on a third of plant-based yoghurts, and only 20% of supermarket options met the recommended 100mg of calcium per 100g.</p> <p>For plant-based cheeses, most (92%) were not fortified with calcium. Their sodium content varied from 390mg to 1,400mg per 100g, and saturated fat ranged from 0g to 28g per 100g.</p> <h2>So, what should we consider when shopping?</h2> <p>As a general principle, try to choose whole plant foods, such as unprocessed legumes, beans or tofu. These foods are packed with vitamins and minerals. They’re also high in dietary fibre, which is good for your gut health and keeps you fuller for longer.</p> <p>If opting for a processed plant-based food, here are five tips for choosing a healthier option.</p> <p><strong>1. Watch the sodium</strong></p> <p>Plant-based meat alternatives can be high in sodium, so look for products that have <a href="https://www.eatforhealth.gov.au/eating-well/how-understand-food-labels/food-labels-what-look">around</a> 150-250mg sodium per 100g.</p> <p><strong>2. Pick canned beans and legumes</strong></p> <p>Canned chickpeas, lentils and beans can be healthy and low-cost <a href="https://www.heartfoundation.org.au/getmedia/71522940-decf-436a-ba44-cd890dc18036/Meat-Free-Recipe-Booklet.pdf">additions to many meals</a>. Where you can, choose canned varieties with no added salt, especially when buying baked beans.</p> <p><strong>3. Add herbs and spices to your tofu</strong></p> <p>Tofu can be a great alternative to meat. Check the label and pick the option with the highest calcium content. We found flavoured tofu was higher in salt and sugar content than minimally processed tofu. So it’s best to pick an unflavoured option and add your own flavours with spices and herbs.</p> <p><strong>4. Check the calcium</strong></p> <p>When choosing a non-dairy alternative to milk, such as those made from soy, oat, or rice, check it is fortified with calcium. A good alternative to traditional dairy will have at least 100mg of calcium per 100g.</p> <p><strong>5. Watch for saturated fat</strong></p> <p>If looking for a lower saturated fat option, almond, soy, rice and oat varieties of milk and yoghurt alternatives have much lower saturated fat content than coconut options. Pick those with less than 3g per 100g.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/222991/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/laura-marchese-1271636">Laura Marchese</a>, PhD Student at the Institute for Physical Activity and Nutrition, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a> and <a href="https://theconversation.com/profiles/katherine-livingstone-324808">Katherine Livingstone</a>, NHMRC Emerging Leadership Fellow and Senior Research Fellow at the Institute for Physical Activity and Nutrition, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a></em></p> <p><em>Image credits: Getty Images</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Foods to avoid if you have acid reflux or digestion issues

<p><strong>What common foods are good and bad for your belly?</strong></p> <p>Foods containing rapidly fermentable carbohydrates called FODMAPs can feed bacteria in the gut and may be responsible for gut inflammation, gas, bloating and other uncomfortable tummy troubles in some people. Cutting back on foods that contain FODMAPs may help improve your digestion and eliminate GI problems. </p> <p>“An anti-inflammatory diet is high in fibre-rich foods, which promote the growth of healthy bacteria in the gut (one way the diet assists to control inflammation),” says registered dietitian Maxine Smith. A FODMAP diet, which is low in fermentable carbohydrates, is low in fibre and may be beneficial for some people with gastrointestinal problems. </p> <p>In general, a low FODMAPs diet isn’t recommended for people unless they have a condition like irritable bowel syndrome that hasn’t responded to other treatments or dietary changes.</p> <p><strong>Watermelon: Avoid</strong></p> <p>This lovely summer treat isn’t as harmless as all the water it contains. Watermelon is high in fructose, fructans and polyols, which are FODMAPs. Remember, the more the FODMAPs, the more potential for tummy trouble in people who are sensitive to them.</p> <p><strong>Fermented foods: Enjoy some, avoid some</strong></p> <p>Some fermented foods are good for your tummy; others can create problems for certain people, according to an article published by Harvard Medical School. Fermented foods include wine, cheese, vinegar, miso, yoghurt, sauerkraut and pickles. </p> <p>In yoghurt, milk is combined with bacteria that break down some of the lactose, so what remains may be easier for your stomach to process. So fermented foods such as yoghurt are often considered “probiotic foods” that are good for your gut. Look for dairy products that are low in lactose and your digestion should be A-OK.</p> <p><strong>Pistachios, cashews, hazelnuts and almonds: Avoid</strong></p> <p>Most nuts are good for your tummy, but pistachios and cashews are high in fructans and GOS (galacto-oligosaccharides), both FODMAPs. Hazelnuts and almonds are a little higher in FODMAPs than some other nuts so eat them in limited quantities (10 nuts or 1 tablespoon of nut butter per serving). Steer clear of almond milk, which is made with large amounts of almonds.</p> <p><strong>Acidic foods: Enjoy with caution</strong></p> <p>In almost every list of “the worst foods for digestion,” you’ll find acidic foods like oranges and tomatoes. These are commonly thought to cause heartburn, but studies have shown that acidic foods don’t have any effect on LES pressure (or pressure on the lower oesophageal sphincter, a valve that acts as the doorway between the oesophagus and the stomach) and don’t cause heartburn symptoms. </p> <p>However, if you have severe acid reflux that hasn’t been treated and has irritated the oesophagus, acidic foods can be like “salt in the wound.” So if you find that oranges or tomatoes do make your heartburn feel worse, replace them with other fruits.</p> <p><strong>Dairy foods: Enjoy some, avoid some</strong></p> <p>Not all dairy foods have equal amounts of lactose, which can cause digestion issues, and even those with lactose intolerance are usually okay with small amounts of lactose. That means that not all milk, cheeses and dairy products are tummy twisters. </p> <p>Hard cheeses, like cheddar, Swiss or Parmesan, generally have less than a gram of lactose per serving. According to the Cleveland Clinic, you may want to avoid dairy such as “chocolate shakes or drinks, milkshakes, whole milk fat yoghurt, whole milk fat (4%) cottage cheese, and full-fat cheese.”</p> <p><strong>Soy foods: Enjoy some, avoid some</strong></p> <p>Whole soybeans (often sold as edamame), like other beans, are a source of GOS, which are hard-to-digest chains of sugars. Tofu and tempeh are made using processes that eliminate some of the GOS, making them easier on your digestion. What about soy milk? It depends. </p> <p>If soy milk is made with only soybean isolates or soy protein, then it should be low in FODMAPs. Soy milk made with whole soybeans is likely a source of GOS, making it a gassy beverage for some, so read the ingredients.</p> <p><strong>Blackberries: Avoid</strong></p> <p>Strawberries, blueberries, blackberries – which is the odd one out here? Blackberries are also rich in antioxidants, but they have sugar alcohols called polyols, which are difficult to digest and can cause some real problems if your stomach is sensitive. (Check out these foods that GI doctors always avoid.)</p> <p><strong>Tomato and tomato products: Enjoy some, avoid some</strong></p> <p>Fresh and canned tomatoes are fine for your tummy. But tomato paste is a concentrated form of tomato that has excess fructose, a FODMAP that makes it a no-no except in small quantities. And tomato sauces? If they’re homemade, they’re fine to eat (just don’t cook it to the point where all the juices are lost). </p> <p>Most commercial sauces have onions and garlic (FODMAPs), added sugar (which may make it carb-dense), and salt (which bloats you), so steer clear of the store-bought variety.</p> <p><strong>Grapefruit: Enjoy with caution</strong></p> <p>Grapefruit does have hard-to-digest fructans, so you should try to limit how much you eat. A few sections should be okay, but don’t eat a half a grapefruit. If you’re looking for citrus, lemon, lime and oranges are your best bets.</p> <p><strong>Milk: Enjoy some, avoid some</strong></p> <p>Most types of animal milk are high in tummy twisting lactose – that means goat’s or sheep’s milk can be just as problematic as cow’s milk. Plant-based milks, such as coconut milk, soy milk or almond milk, are technically not milk at all and generally do not have any lactose. </p> <p>Some, however, including almond milk and soy milk, may contain other FODMAPs that harm your digestion.</p> <p><strong>Corn: Avoid</strong></p> <p>Corn comes in many varieties, such as popcorn, on the cob and in polenta. Fresh sweet corn contains two types of FODMAPs, making corn challenging for some people to digest. Popcorn feels like a light and healthy snack, but it’s actually carb-dense (it has about 64 grams of carbs per 100 grams), which can upset digestion. </p> <p>Whole cornmeal and corn tortillas seem to be better tolerated by most people. Whole grain polenta is also low in FODMAPs. You may need to experiment a little to figure out which corn products work for you. And stick with only limited quantities (up to 1 cup cooked per serving).</p> <p><strong>Common cabbage: Enjoy</strong></p> <p>Cabbage usually makes it on all the lists of foods that make you gassy, but common green cabbage doesn’t deserve that reputation. It’s actually low in FODMAPs and most of us break it down very well. </p> <p>Red cabbage also seems to be well-tolerated, but savoy and napa cabbage is much higher in FODMAPs and should be limited if you tend to suffer from gas and bloating.</p> <p><strong>Hot sauce: Enjoy with caution</strong></p> <p>Tolerance to hot sauce is very individual. It’s more problematic for those with heartburn. If you would like to try some, pick a brand without onion and garlic.</p> <p><em>Image credits: Getty Images </em></p> <p><em>This article originally appeared on <a href="https://www.readersdigest.co.nz/healthsmart/conditions/foods-to-avoid-if-you-have-acid-reflux-or-digestion-issues?pages=1" target="_blank" rel="noopener">Reader's Digest</a>.</em></p>

Run out of butter or eggs? Here’s the science behind substitute ingredients

<p><em><a href="https://theconversation.com/profiles/paulomi-polly-burey-404695">Paulomi (Polly) Burey</a>, <a href="https://theconversation.com/institutions/university-of-southern-queensland-1069">University of Southern Queensland</a></em></p> <p>It’s an all too common situation – you’re busy cooking or baking to a recipe when you open the cupboard and suddenly realise you are missing an ingredient.</p> <p>Unless you can immediately run to the shops, this can leave you scrambling for a substitute that can perform a similar function. Thankfully, such substitutes can be more successful than you’d expect.</p> <p>There are a few reasons why certain ingredient substitutions work so well. This is usually to do with the chemistry and the physical features having enough similarity to the original ingredient to still do the job appropriately.</p> <p>Let’s delve into some common ingredient substitutions and why they work – or need to be tweaked.</p> <p><iframe id="IitfH" class="tc-infographic-datawrapper" style="border: none;" src="https://datawrapper.dwcdn.net/IitfH/1/" width="100%" height="400px" frameborder="0"></iframe></p> <h2>Oils versus butter</h2> <p>Both butter and oils belong to a chemical class called <a href="https://chem.libretexts.org/Bookshelves/Introductory_Chemistry/Map%3A_Fundamentals_of_General_Organic_and_Biological_Chemistry_(McMurry_et_al.)/23%3A_Lipids/23.01%3A_Structure_and_Classification_of_Lipids">lipids</a>. It encompasses solid, semi-solid and liquid fats.</p> <p>In a baked product the “job” of these ingredients is to provide flavour and influence the structure and texture of the finished item. In cake batters, lipids contribute to creating an emulsion structure – this means combining two liquids that wouldn’t usually mix. In the baking process, this helps to create a light, fluffy crumb.</p> <p>One of the primary differences between butter and oil is that butter is only about 80% lipid (the rest being water), while <a href="https://www.nutritionadvance.com/types-of-cooking-fats-and-oils/">oil is almost 100% lipid</a>. Oil creates a softer crumb but is still a great fat to bake with.</p> <p>You can use a wide range of oils from different sources, such as olive oil, rice bran, avocado, peanut, coconut, macadamia and many more. Each of these may impart different flavours.</p> <p>Other “butters”, such as peanut and cashew butter, aren’t strictly butters but pastes. They impart different characteristics and can’t easily replace dairy butter, unless you also add extra oil.</p> <h2>Aquafaba or flaxseed versus eggs</h2> <p>Aquafaba is the liquid you drain from a can of legumes – such as chickpeas or lentils. It contains proteins, kind of how egg white also contains proteins.</p> <p>The proteins in egg white include albumins, and <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5912395/">aquafaba also contains albumins</a>. This is why it is possible to make meringue from egg whites, or from aquafaba if you’re after a vegan version.</p> <p>The proteins act as a foam stabiliser – they hold the light, airy texture in the product. The concentration of protein in egg white is a bit higher, so it doesn’t take long to create a stable foam. Aquafaba requires more whipping to create a meringue-like foam, but it will bake in a similar way.</p> <p>Another albumin-containing alternative for eggs is <a href="https://foodstruct.com/compare/seeds-flaxseed-vs-egg">flaxseed</a>. These seeds form a thick gel texture when mixed with a little water. The texture is similar to raw egg and can provide structure and emulsification in baked recipes that call for a small amount of egg white.</p> <h2>Lemon plus dairy versus buttermilk</h2> <p>Buttermilk is the liquid left over after churning butter – it can be made from sweet cream, cultured/sour cream or whey-based cream. Buttermilk mostly <a href="https://www.journalofdairyscience.org/article/S0022-0302(06)72115-4/fulltext">contains proteins and fats</a>.</p> <p>Cultured buttermilk has a somewhat tangy flavour. Slightly soured milk can be a good substitute as it contains similar components and isn’t too different from “real” buttermilk, chemically speaking.</p> <p>One way to achieve slightly soured milk is by adding some lemon juice or cream of tartar to milk. Buttermilk is used in pancakes and baked goods to give extra height or volume. This is because the acidic (sour) components of buttermilk interact with baking soda, producing a light and airy texture.</p> <p>Buttermilk can also influence flavour, imparting a slightly tangy taste to pancakes and baked goods. It can also be used in sauces and dressings if you’re looking for a lightly acidic touch.</p> <h2>Honey versus sugar</h2> <p>Honey is a <a href="https://resources.perkinelmer.com/lab-solutions/resources/docs/APP_Analysis-of-Sugars-in-Honey-012101_01.pdf">complex sugar-based syrup</a> that includes floral or botanical flavours and aromas. Honey can be used in cooking and baking, adding both flavour and texture (viscosity, softness) to a wide range of products.</p> <p>If you add honey instead of regular sugar in baked goods, keep in mind that honey imparts a softer, moister texture. This is because it contains more moisture and is a humectant (that is, it likes to hold on to water). It is also less crystalline than sugar, unless you leave it to crystallise.</p> <p>The intensity of sweetness can also be different – some people find honey is sweeter than its granular counterpart, so you will want to adjust your recipes accordingly.</p> <h2>Gluten-free versus regular flour</h2> <p>Sometimes you need to make substitutions to avoid allergens, such as gluten – the protein found in cereal grains such as wheat, rye, barley and others.</p> <p>Unfortunately, gluten is also the component that gives a nice, stretchy, squishy quality to bread.</p> <p>To build this characteristic in a gluten-free product, it’s necessary to have a mixture of ingredients that work together to mimic this texture. Common ingredients used are corn or rice flour, xanthan gum, which acts as a binder and moisture holder, and tapioca starch, which is a good water absorbent and can aid with binding the dough. <!-- Below is The Conversation's page counter tag.

“Completely tacky”: Bride slammed for asking for dinner payment

<p dir="ltr">A bride has caused a stir online after asking if it is appropriate to ask her wedding guests to pay for their meal when they RSVP to the big day. </p> <p dir="ltr">The woman took to a popular wedding Facebook page to ask the opinions of other brides, sharing an example of her invitation created by her wedding planner. </p> <p dir="ltr">The invitation asks guests to confirm whether or not they will be attending the nuptials, before asking if the guest intends to eat at the wedding ceremony, and which meal they would prefer. </p> <p dir="ltr">The price of each meal was also included: $20 for grilled chicken with rice, mashed potatoes and green beans and $25 for a salmon alternative.</p> <p dir="ltr">“We invite you to eat with us but ask for you to provide your own payment. Please select which meal you'd prefer,” the invite stated. </p> <p dir="ltr">“My wedding venue requires me to purchase food through them for the reception, but has said people sometimes choose this option,” the woman wrote on Facebook. </p> <p dir="ltr">“Nothing about my reception is very typical anyway, SO I'm wondering how insane or rude or cost-effective/smart this is.”</p> <p dir="ltr">“The planner set me this as an example of how to present it to guests.”</p> <p dir="ltr">But when the post was quickly criticised by others, the bride clarified the event was more of a “fun dinner party” rather than a “wedding” as she and her partner had already legally married five months prior. </p> <p dir="ltr">“Ultimately I'll do what I want BUT I did not choose this option. It was only a suggestion from the venue that I was curious about others' opinions on,” she added. </p> <p dir="ltr">“This is for the reception. I'm most definitely not asking for money or gifts and by the time they come to the reception, we will have already been married for five months.”</p> <p dir="ltr">The post was shared in another wedding shaming Facebook group and critiqued by dozens of wedding experts.</p> <p dir="ltr">“Oh hell no! This is completely tacky!” one wrote, another said, “So she asks if it is rude then gets offended when people say it's rude?”</p> <p dir="ltr">“I am a veteran pro planner and would NEVER suggest this!” another said. </p> <p dir="ltr">Someone else wrote, “I'm especially shaming the venue for suggesting that people often pawn off the cost of dinner to their guests. Encouraging rude behaviour.”</p> <p dir="ltr"><em>Image credits: Getty Images / Facebook</em></p>

Alzheimer’s may have once spread from person to person, but the risk of that happening today is incredibly low

<p><em><a href="https://theconversation.com/profiles/steve-macfarlane-4722">Steve Macfarlane</a>, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a></em></p> <p>An article published this week in the prestigious journal <a href="https://www.nature.com/articles/s41591-023-02729-2">Nature Medicine</a> documents what is believed to be the first evidence that Alzheimer’s disease can be transmitted from person to person.</p> <p>The finding arose from long-term follow up of patients who received human growth hormone (hGH) that was taken from brain tissue of deceased donors.</p> <p>Preparations of donated hGH were used in medicine to treat a variety of conditions from 1959 onwards – including in Australia from the mid 60s.</p> <p>The practice stopped in 1985 when it was discovered around 200 patients worldwide who had received these donations went on to develop <a href="https://www.vdh.virginia.gov/epidemiology/epidemiology-fact-sheets/creutzfeldt-jakob-disease-cjd/">Creuztfeldt-Jakob disease</a> (CJD), which causes a rapidly progressive dementia. This is an otherwise extremely rare condition, affecting roughly one person in a million.</p> <h2>What’s CJD got to do with Alzehimer’s?</h2> <p>CJD is caused by prions: infective particles that are neither bacterial or viral, but consist of abnormally folded proteins that can be transmitted from cell to cell.</p> <p>Other prion diseases include kuru, a dementia seen in New Guinea tribespeople caused by eating human tissue, scrapie (a disease of sheep) and variant CJD or bovine spongiform encephalopathy, otherwise known as mad cow disease. This raised <a href="https://en.wikipedia.org/wiki/United_Kingdom_BSE_outbreak">public health concerns</a> over the eating of beef products in the United Kingdom in the 1980s.</p> <h2>Human growth hormone used to come from donated organs</h2> <p>Human growth hormone (hGH) is produced in the brain by the pituitary gland. Treatments were originally prepared from purified human pituitary tissue.</p> <p>But because the amount of hGH contained in a single gland is extremely small, any single dose given to any one patient could contain material from around <a href="https://www.cdc.gov/mmwr/preview/mmwrhtml/00000563.htm">16,000 donated glands</a>.</p> <p>An average course of hGH treatment lasts around four years, so the chances of receiving contaminated material – even for a very rare condition such as CJD – became quite high for such people.</p> <p>hGH is now manufactured synthetically in a laboratory, rather than from human tissue. So this particular mode of CJD transmission is no longer a risk.</p> <h2>What are the latest findings about Alzheimer’s disease?</h2> <p>The Nature Medicine paper provides the first evidence that transmission of Alzheimer’s disease can occur via human-to-human transmission.</p> <p>The authors examined the outcomes of people who received donated hGH until 1985. They found five such recipients had developed early-onset Alzheimer’s disease.</p> <p>They considered other explanations for the findings but concluded donated hGH was the likely cause.</p> <p>Given Alzheimer’s disease is a much more common illness than CJD, the authors presume those who received donated hGH before 1985 may be at higher risk of developing Alzheimer’s disease.</p> <p>Alzheimer’s disease is caused by presence of two abnormally folded proteins: amyloid and tau. There is <a href="https://actaneurocomms.biomedcentral.com/articles/10.1186/s40478-017-0488-7">increasing evidence</a> these proteins spread in the brain in a <a href="https://pubmed.ncbi.nlm.nih.gov/8086126/">similar way to prion diseases</a>. So the mode of transmission the authors propose is certainly plausible.</p> <p>However, given the amyloid protein deposits in the brain <a href="https://www.nia.nih.gov/news/estimates-amyloid-onset-may-predict-alzheimers-progression">at least 20 years</a> before clinical Alzheimer’s disease develops, there is likely to be a considerable time lag before cases that might arise from the receipt of donated hGH become evident.</p> <h2>When was this process used in Australia?</h2> <p>In Australia, donated pituitary material <a href="https://www.health.gov.au/sites/default/files/documents/2022/07/the-cjd-review-final-report.pdf">was used</a> from 1967 to 1985 to treat people with short stature and infertility.</p> <p><a href="https://www.health.gov.au/sites/default/files/documents/2022/07/the-cjd-review-final-report.pdf">More than 2,000 people</a> received such treatment. Four developed CJD, the last case identified in 1991. All four cases were likely linked to a single contaminated batch.</p> <p>The risks of any other cases of CJD developing now in pituitary material recipients, so long after the occurrence of the last identified case in Australia, are <a href="https://www.mja.com.au/journal/2010/193/6/iatrogenic-creutzfeldt-jakob-disease-australia-time-amend-infection-control">considered to be</a> incredibly small.</p> <p>Early-onset Alzheimer’s disease (defined as occurring before the age of 65) is uncommon, accounting for <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4356853/">around 5%</a> of all cases. Below the age of 50 it’s rare and likely to have a genetic contribution.</p> <h2>The risk is very low – and you can’t ‘catch’ it like a virus</h2> <p>The Nature Medicine paper identified five cases which were diagnosed in people aged 38 to 55. This is more than could be expected by chance, but still very low in comparison to the total number of patients treated worldwide.</p> <p>Although the long “incubation period” of Alzheimer’s disease may mean more similar cases may be identified in the future, the absolute risk remains very low. The main scientific interest of the article lies in the fact it’s first to demonstrate that Alzheimer’s disease can be transmitted from person to person in a similar way to prion diseases, rather than in any public health risk.</p> <p>The authors were keen to emphasise, as I will, that Alzheimer’s cannot be contracted via contact with or providing care to people with Alzheimer’s disease.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/222374/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/steve-macfarlane-4722"><em>Steve Macfarlane</em></a><em>, Head of Clinical Services, Dementia Support Australia, &amp; Associate Professor of Psychiatry, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a></em></p> <p><em>Image credits: Getty Images </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

The best diet for 2024

<p>Over years of research and diet rankings, there is one regimen that scientists have crowned the "Best Diet Overall" for seven years in a row. </p> <p>The Mediterranean diet has topped the list in <a href="https://health.usnews.com/best-diet/best-diets-overall" target="_blank" rel="noopener"><em>US News and World Reports’</em></a> annual ranking for 2024, followed by the DASH diet, and the MIND diet coming in third.  </p> <p>The ranking is based off the findings of a panel of leading medical and nutrition experts, who analyse the nutritional completeness, health risks and benefits, long-term sustainability and  effectiveness of the diet in addressing its goals. </p> <p><strong>What sets it apart from other diets? </strong></p> <p>The Mediterranean diet emphasises multiple servings of fruits and vegetables daily, alongside whole grains, legumes, nuts, olive oil and seafood. </p> <p>Red meats, dairy and poultry are consumed occasionally and in moderation, and highly processed foods and added sugars are generally avoided. </p> <h4><strong>What are its benefits?</strong></h4> <p>The experts found that following the diet long term can increase the odds of living a longer, healthier life, with a few other studies suggesting it lowers the risk of heart disease and Type 2 diabetes, while potentially slowing cognitive decline.</p> <p>“It’s a way of life, it’s a cuisine, it dates back thousands of years, and in the last five to six decades, it is the most highly researched cuisine in the world,” said Dr Catherine Itsiopoulos, a professor of nutrition and dietetics at RMIT University in Melbourne.</p> <p><strong>Lowers risk of heart disease</strong></p> <p>A 2021 research review found that the diet has been shown to reduce the risk of coronary heart disease in women by 29 per cent and stroke by 13 per cent. </p> <p>A 2017 analysis found that on average it lowers the risk of coronary heart disease, heart attacks and strokes by 40 per cent. </p> <p>Experts suggest that this may be because  the fats in olive oil, seeds, fish and nuts are monounsaturated or polyunsaturated fats aka healthy fats. </p> <p>Additionally, because of its emphasis on fruits, vegetables and legumes, which contain antioxidants and other beneficial compounds, it is believed to combat chronic inflammation. </p> <p><strong>Lowers chances of developing type 2 diabetes </strong></p> <p>Because this diet relies heavily on honey and cinnamon as sweeteners, and fruits as a primary source of sugar, it reduces the risk of developing this disease. </p> <p>One study conducted on 300,000 participants found that those who were on the Mediterranean diet had a nearly 30 per cent lower risk of Type 2 diabetes. </p> <p><strong>Good for your gut</strong></p> <p>The diet contains a lot of fibre which are associated with more regular bowel movements, lower blood pressure, cholesterol and blood sugar levels, according to the Food and Drug Administration.</p> <p>This is because good bacteria in our stomachs feed off fibre, which creates a stronger lining in the intestines. </p> <p>There are a few other potential health benefits including reducing risk of dementia among seniors by almost 25 per cent, and lowering the risk of death from cancer including breast, colorectal, head and neck and lung cancers. </p> <p>See the full list <a href="https://health.usnews.com/best-diet/best-diets-overall" target="_blank" rel="noopener">here</a>. </p> <p><em>Image: Getty</em></p> <p> </p>

5 ways to avoid weight gain and save money on food this Christmas

<p><em><a href="https://theconversation.com/profiles/nick-fuller-219993">Nick Fuller</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p>As Christmas approaches, so does the challenge of healthy eating and maintaining weight-related goals. The season’s many social gatherings can easily tempt us to indulge in calorie-rich food and celebratory drinks. It’s why we typically <a href="https://www.nejm.org/doi/full/10.1056/NEJMc1602012">gain weight</a> over Christmas and then struggle to take it off for the <a href="https://www.sciencedirect.com/science/article/pii/S0031938414001528">remainder of the year</a>.</p> <p>Christmas 2023 is also exacerbating cost-of-living pressures, prompting some to rethink their food choices. Throughout the year, <a href="https://dvh1deh6tagwk.cloudfront.net/finder-au/wp-uploads/2023/03/Cost-of-Living-Report-2023.pdf">71% of Australians</a> – or 14.2 million people – <a href="https://retailworldmagazine.com.au/rising-cost-of-living-forces-aussies-to-change-diets/">adapted</a> their eating behaviour in response to rising costs.</p> <p>Fortunately, there are some simple, science-backed hacks for the festive season to help you celebrate with the food traditions you love without impacting your healthy eating habits, weight, or hip pocket.</p> <h2>1. Fill up on healthy pre-party snacks before heading out</h2> <p>If your festive season is filled with end-of-year parties likely to tempt you to fill up on finger foods and meals high in fat, salt, and sugar and low in nutritional value, have a healthy pre-event snack before you head out.</p> <p><a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5015032/#sec-a.g.atitle">Research</a> shows carefully selected snack foods can impact satiety (feelings of fullness after eating), potentially reducing the calories you eat later. High-protein, high-fibre snack foods have the strongest effect: because they take longer to digest, our hunger is satisfied for longer.</p> <p>So enjoy a handful of nuts, a tub of yoghurt, or a serving of hummus with veggie sticks before you head out to help keep your healthy eating plan on track.</p> <h2>2. Skip the low-carb drinks and enjoy your favourites in moderation</h2> <p>Despite the marketing promises, low-carb alcoholic drinks <a href="https://onlinelibrary.wiley.com/doi/10.1002/hpja.531">aren’t better for our health or waistlines</a>.</p> <p>Many low-carb options have a similar amount of carbohydrates as regular options but lull us into thinking they’re better, so we drink more. A <a href="https://www.vichealth.vic.gov.au/sites/default/files/K-013_Low-carb-beer_FactSheet_FINAL.pdf">survey</a> found 15% of low-carb beer drinkers drank more beer than they usually would because they believed it was healthier for them.</p> <p>A typical lager or ale will contain less than 1.5 grams of carbohydrate per 100 ml while the “lower-carb” variety can range anywhere from 0.5 grams to 2.0 grams. The calories in drinks come from the alcohol itself, not the carbohydrate content.</p> <p>Next time you go to order, think about the quantity of alcohol you’re drinking rather than the carbs. Make sure you sip lots of water in between drinks to stay hydrated, too.</p> <h2>3. Don’t skimp on healthy food for Christmas Day – it’s actually cheaper</h2> <p>There’s a perception that healthy eating is more expensive. But studies show this is a misconception. A <a href="https://southwesthealthcare.com.au/swh-study-finds-eating-a-healthier-diet-is-actually-cheaper-at-the-checkout/#:%7E:text=A%20recent%20study%20from%20the,does%20not%20meet%20the%20guidelines">recent analysis</a> in Victoria, for example, found following the Australian Dietary Guidelines cost the average family A$156 less a fortnight than the cost of the average diet, which incorporates packaged processed foods and alcohol.</p> <p>So when you’re planning your Christmas Day meal, give the pre-prepared, processed food a miss and swap in healthier ingredients:</p> <ul> <li> <p>swap the heavy, salted ham for leaner and lighter meats such as fresh seafood. Some seafood, such as prawns, is also tipped to be cheaper this year thanks to <a href="https://www.smh.com.au/goodfood/lobsters-up-prawns-stable-a-buying-guide-to-seafood-this-christmas-20231208-p5eq3m.html">favourable weather conditions</a> boosting local supplies</p> </li> <li> <p>for side dishes, opt for fresh salads incorporating seasonal ingredients such as mango, watermelon, peach, cucumber and tomatoes. This will save you money and ensure you’re eating foods when they’re freshest and most flavoursome</p> </li> </ul> <ul> <li> <p>if you’re roasting veggies, use healthier cooking oils like olive as opposed to vegetable oil, and use flavourful herbs instead of salt</p> </li> <li> <p>if there’s an out-of-season vegetable you want to include, look for frozen and canned substitutes. They’re cheaper, and <a href="https://www.sciencedirect.com/science/article/pii/S0889157517300418">just as nutritious</a> and tasty because the produce is usually frozen or canned at its best. Watch the sodium content of canned foods, though, and give them a quick rinse to remove any salty water</p> </li> <li> <p>give store-bought sauces and dressings a miss, making your own from scratch using fresh ingredients.</p> </li> </ul> <h2>4. Plan your Christmas food shop with military precision</h2> <p>Before heading to the supermarket to shop for your Christmas Day meal, create a detailed meal plan and shopping list, and don’t forget to check your pantry and fridge for things you already have.</p> <p><a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4586574/">Eating beforehand</a> and shopping with a plan in hand means you’ll only buy what you need and <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8206473/">avoid impulse purchasing</a>.</p> <p>When you’re shopping, price check everything. Comparing the cost per 100 grams is the most effective way to save money and get the best value. Check prices on products sold in different ways and places, too, such as nuts you scoop yourself versus prepacked options.</p> <h2>5. Don’t skip breakfast on Christmas Day</h2> <p>We’ve all been tempted to skip or have a small breakfast on Christmas morning to “save” the calories for later. But this plan will fail when you sit down at lunch hungry and find yourself eating far more calories than you’d “saved” for.</p> <p><a href="https://pubmed.ncbi.nlm.nih.gov/32073608/">Research</a> shows a low-calorie or small breakfast leads to increased feelings of hunger, specifically appetite for sweets, across the course of the day.</p> <p>What you eat for breakfast on Christmas morning is just as important too – choosing the right foods will <a href="https://theconversation.com/im-trying-to-lose-weight-and-eat-healthily-why-do-i-feel-so-hungry-all-the-time-what-can-i-do-about-it-215808">help you manage your appetite</a> and avoid the temptation to overindulge later in the day.</p> <p><a href="https://pubmed.ncbi.nlm.nih.gov/24703415/">Studies</a> show a breakfast containing protein-rich foods, such as eggs, will leave us feeling fuller for longer.</p> <p>So before you head out to the Christmas lunch, have a large, nutritionally balanced breakfast, such as eggs on wholegrain toast with avocado.</p> <p><em>At the Boden Group, Charles Perkins Centre, we are studying the science of obesity and running clinical trials for weight loss.

5 ways to make Christmas lunch more ethical this year

<p><em><a href="https://theconversation.com/profiles/rebecca-reynolds-141045">Rebecca Reynolds</a>, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a></em></p> <p>What we eat matters - not just for our health, but for the planet and other living things too.</p> <p>Most of us know meat consumption <a href="https://www.nature.com/articles/s43016-021-00358-x.epdf">contributes to global warming</a> and many of us are aware of animal cruelty and human exploitation in global food supply chains.</p> <p>So what are some ways we can use our “fork power” to make our Christmas lunch more ethical this year?</p> <h2>1. Replace your turkey or ham with a vegetarian dish</h2> <p>Vegetarian options are not boring or tasteless — just look at this <a href="https://annajones.co.uk/recipe/squash-chestnut-roast">festive squash and chestnut roast</a>.</p> <p>A plant-focused diet has strong <a href="https://eatforum.org/eat-lancet-commission/the-planetary-health-diet-and-you/">environmental benefits</a>. Livestock not only <a href="https://theconversation.com/cop28-begins-4-issues-that-will-determine-if-the-un-climate-summit-is-a-success-from-methane-to-money-218869">produce greenhouse gas</a> when they burp, they take up huge amounts of <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9024616/">land and fresh water</a>.</p> <p>Reducing the number of animal products on your plate also reduces the likelihood you are contributing to the suffering of animals. Even though many countries have <a href="https://www.agriculture.gov.au/agriculture-land/animal/welfare/standards-guidelines">ethical standards</a> for the treatment of farm animals, these are not always followed, and many of the practices considered legal <a href="https://www.abc.net.au/news/rural/2023-03-28/pig-slaughter-methods-defended-by-pork-industry/102153822">still cause pain and suffering to animals</a>.</p> <p>While cutting out all animal products can be difficult, any reduction in consumption makes a difference. For example, consider swapping out the brie on your Christmas platter for hummus this year.</p> <h2>2. Choose ‘good fish’</h2> <p>Many of us don’t realise fish and other seafood is often sourced unsustainably, negatively impacting ocean ecosystems and wildlife. An Australian organisation called GoodFish produces a <a href="https://goodfish.org.au/">Sustainable Seafood Guide</a>, where you can find out how ethical the fish you buy is.</p> <p>Unfortunately, many salmon products are <a href="https://goodfish.org.au/sustainable-seafood-guide/?q=salmon">not as sustainable</a> as companies claim them to be. In comparison, farmed Australian barramundi, Murray cod, prawns, oysters and mussels, and wild-caught Australian Eastern and Western rock lobsters are classified as better choices.</p> <p>Additionally, an international not-for-profit organisation called the <a href="https://www.msc.org/en-au">Marine Stewardship Council</a> has an “MSC blue fish tick label” certification scheme, which endorses products from well-managed and sustainable fisheries. Have a look for MSC-certified frozen crumbed fish in your next shop.</p> <h2>3. Choose at least one organic item, such as your roast potatoes</h2> <p><a href="https://www.fao.org/organicag/oa-faq/oa-faq6/en/">Organic agriculture</a> aims to produce food while establishing an ecological balance to prevent soil infertility or pest problems over the longer term. It strengthens the dynamics and carbon storage of soil, stops freshwater pollution with synthetic fertilisers and pesticides, reduces the use of fossil fuels needed to produce these chemicals, and promotes biodiversity.</p> <p>Yes, organic products are more expensive, but you will hopefully now feel they are worth it (you could also look out for organic produce that is reduced in price during “on special” promotions).</p> <h2>4. Choose Fairtrade chocolate</h2> <p>Of course, humans are heavily involved in the production, packaging and transport of the food we eat every day. Organisations such as <a href="https://fairtradeanz.org/">Fairtrade Australia and New Zealand</a> and <a href="https://www.rainforest-alliance.org/">Rainforest Alliance</a> aim to improve the lives of rural farmers and workers in developing countries – who otherwise might get unfair deals for their produce and work (these organisations also target environmental issues).</p> <p>You can buy Fairtrade- and Rainforest Alliance-certified products in supermarkets (and elsewhere), such as chocolate, coffee, tea – and even ice cream.</p> <p>Similarly, there are companies called <a href="https://bcorporation.com.au/find-b-corps/">B Corps</a>, or Certified B Corporations. These are organisations that also care about social and environmental issues. B Corp food products can also be found in supermarkets (and elsewhere), and include things like peanut butter and seaweed snacks.</p> <h2>5. Make friends with your freezer</h2> <p>When we waste food, we are wasting the energy, land, water and chemicals that were used during the <a href="https://www.un.org/en/climatechange/science/climate-issues/food">long process</a> of getting it into your home.</p> <p>Lots of us worry at Christmas about “having enough food for everyone”, and consequently buy too much. Why not talk through your menu plan with someone else before you go shopping, to check that you are not anxiety-buying to feed 50 people (instead of your extended family of ten).</p> <p>But even with calm planning, you may still have leftover food. If this happens, you can get creative with using leftovers on Boxing Day (OzHarvest has some recipes online, including <a href="https://www.ozharvest.org/use-it-up/tips/">Christmas rockyroad</a>), or you can preserve food to eat at a later date using your cool friend, the freezer.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/218351/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/rebecca-reynolds-141045">Rebecca Reynolds</a>, Adjunct lecturer and nutritionist, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a></em></p> <p><em>Image credits: Getty Images</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Genius Christmas hack divides viewers

<p>Christmas, a time when the kitchen becomes a battlefield and culinary warriors seek ingenious hacks to conquer the chaos!</p> <p>Thankfully, Janelle from @thedailynelly on Instagram, armed with the wisdom of her grandma, has unveiled a potato-cleaning strategy that has shaken the very foundations of traditional holiday prep.</p> <p>Enter "Grandma's best Thanksgiving secret" – a cryptic title that foreshadows a culinary revelation of epic proportions. And yes, we know it's for Thanksgiving – but we are just going to give some thanks and use it for Christmas prep anyway.</p> <p>Janelle took to Instagram to showcase her revolutionary potato-cleaning hack for her followers and – spoiler alert – it involves a dishwasher, and things are about to get wild.</p> <p>As Janelle stacks unwashed potatoes into the dishwasher, she confidently claims that this unorthodox method saves her both time and effort. The video unfolds like a suspenseful thriller, with the person behind the camera questioning her every move. "This is the best way to do it. It saves you so much time," Janelle declares with the conviction of someone who has cracked the Da Vinci Code of holiday cooking.</p> <p>In a daring move, she populates not only the top rack with filthy potatoes but also the lower shelf, even utilising the cutlery holder – because who needs spoons when you can have spuds? Janelle defends her potato-loading strategy, pointing out that traditional methods in a bowl are impractical when faced with three bags of potatoes. Practicality, meet pandemonium.</p> <p>Janelle also points out – a little redundantly, but to be honest you never really know the caliber of person watching Instagram videos – that it's crucial not to use any dishwashing tablets or soap in this peculiar cleaning ritual, because, you know, that would be weird. We wouldn't want our spuds to taste like lavender-scented detergent, now would we?</p> <p>The climax arrives when the four-minute rinse cycle is over – a pivotal moment in this culinary odyssey. Janelle gleefully showcases the now pristine potatoes, claiming victory over the tedious hand-washing process. "They're clean, you didn't have to hand wash them. I'm telling you – it saves time on Christmas when you're hosting a tonne of people," she declares triumphantly.</p> <p>However, the internet, ever the skeptic, has of course reacted with horror and disbelief. Some commenters expressed their disgust, labelling the dishwasher technique as "gross" and "nasty". </p> <blockquote class="instagram-media" style="background: #FFF; border: 0; border-radius: 3px; box-shadow: 0 0 1px 0 rgba(0,0,0,0.5),0 1px 10px 0 rgba(0,0,0,0.15); margin: 1px; max-width: 540px; min-width: 326px; padding: 0; width: calc(100% - 2px);" data-instgrm-captioned="" data-instgrm-permalink="https://www.instagram.com/reel/Cz7Af8oulYb/?utm_source=ig_embed&utm_campaign=loading" data-instgrm-version="14"> <div style="padding: 16px;"> <div style="display: flex; flex-direction: row; align-items: center;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 40px; margin-right: 14px; width: 40px;"> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 100px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 60px;"> </div> </div> </div> <div style="padding: 19% 0;"> </div> <div style="display: block; height: 50px; margin: 0 auto 12px; width: 50px;"> </div> <div style="padding-top: 8px;"> <div style="color: #3897f0; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: 550; line-height: 18px;">View this post on Instagram</div> </div> <div style="padding: 12.5% 0;"> </div> <div style="display: flex; flex-direction: row; margin-bottom: 14px; align-items: center;"> <div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(0px) translateY(7px);"> </div> <div style="background-color: #f4f4f4; height: 12.5px; transform: rotate(-45deg) translateX(3px) translateY(1px); width: 12.5px; flex-grow: 0; margin-right: 14px; margin-left: 2px;"> </div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(9px) translateY(-18px);"> </div> </div> <div style="margin-left: 8px;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 20px; width: 20px;"> </div> <div style="width: 0; height: 0; border-top: 2px solid transparent; border-left: 6px solid #f4f4f4; border-bottom: 2px solid transparent; transform: translateX(16px) translateY(-4px) rotate(30deg);"> </div> </div> <div style="margin-left: auto;"> <div style="width: 0px; border-top: 8px solid #F4F4F4; border-right: 8px solid transparent; transform: translateY(16px);"> </div> <div style="background-color: #f4f4f4; flex-grow: 0; height: 12px; width: 16px; transform: translateY(-4px);"> </div> <div style="width: 0; height: 0; border-top: 8px solid #F4F4F4; border-left: 8px solid transparent; transform: translateY(-4px) translateX(8px);"> </div> </div> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center; margin-bottom: 24px;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 224px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 144px;"> </div> </div> <p style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; line-height: 17px; margin-bottom: 0; margin-top: 8px; overflow: hidden; padding: 8px 0 7px; text-align: center; text-overflow: ellipsis; white-space: nowrap;"><a style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: normal; line-height: 17px; text-decoration: none;" href="https://www.instagram.com/reel/Cz7Af8oulYb/?utm_source=ig_embed&utm_campaign=loading" target="_blank" rel="noopener">A post shared by The Daily Nelly (@thedailynelly)</a></p> </div> </blockquote> <p>Concerns about dishwasher residue and the efficiency of the method compared to traditional hand washing also echo through the comments.

Bring a plate! What to take to Christmas lunch that looks impressive (but won’t break the bank)

<p><em><a href="https://theconversation.com/profiles/lauren-ball-14718">Lauren Ball</a>, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a>; <a href="https://theconversation.com/profiles/amy-kirkegaard-1401256">Amy Kirkegaard</a>, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a>; <a href="https://theconversation.com/profiles/breanna-lepre-1401257">Breanna Lepre</a>, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a>, and <a href="https://theconversation.com/profiles/emily-burch-438717">Emily Burch</a>, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a></em></p> <p>Christmas lunch is at your friend’s house this year, and they’ve asked you to bring a plate. Money is tight. So, you find yourself wondering, “What’s cheap, healthy but also looks impressive?”</p> <p>While a tray of mangoes would certainly be a cheap, healthy and colourful contribution, you want to look as if you’ve put in a bit of effort.</p> <p>If you’re struggling for inspiration, here are some tried and tested ideas.</p> <h2>First, choose your ingredients</h2> <p>Check your pantry for inspiration or ingredients. Crackers, dried fruit or nuts are great ideas for a charcuterie board. You can use herbs and spices to add flavour to dishes, or you could use up packets of dried pasta to make a <a href="https://nomoneynotime.com.au/healthy-easy-recipes/salmon-and-pasta-salad">pasta salad</a>. This is also a great way to clean out your pantry.</p> <p>Focus on fruit and vegetables that are in season, so are cheaper and more readily available. Keep an eye out at your local fruit and veggie shop or market as it will usually have in-season fruit and vegetables in bulk quantities at reduced prices. Check out <a href="http://seasonalfoodguide.com/australia-general-seasonal-fresh-produce-guide-fruits-vegetables-in-season-availability.html">this seasonal food guide</a> to help you plan your Christmas menu.</p> <p>Ask around for deals by chatting to your local butcher, fishmonger or grocer and let them know your budget. They may suggest cheaper cuts of meat (such as, <a href="https://www.australianbutchersguild.com.au/the-blog/the-abg-blog/underrated-cuts-of-beef/">oyster</a>, <a href="https://www.australianbeef.com.au/know-your-meat/beef-cuts/">blades, rump caps</a>).

Slow-cooked meals can be frozen and can come in handy for left-overs.</p> <p>Lean into <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4608274/">legumes</a>. These are packed with fibre, protein, vitamins and minerals. They are also budget-friendly and a great way to add texture to salads. Tinned chickpeas, or cannellini, kidney, or butter beans are quick and easy additions that can make filling dishes go further. You could even turn tinned chickpeas into homemade hommus for a healthy and delicious side dish. Check out these healthy legume <a href="https://nomoneynotime.com.au/healthy-easy-recipes/filter/keywords--legumes">recipes</a>.</p> <h2>7 ways to keep food costs down this Christmas</h2> <p><strong>1. Plan ahead</strong></p> <p>Plan your menu by asking how many people are coming and checking for any food preferences or dietary requirements. Check for items you already have at home, and make a shopping list for only what you <a href="https://www.emerald.com/insight/content/doi/10.1108/BFJ-12-2017-0726/full/html">need</a>.</p> <p><strong>2. Use free recipes</strong></p> <p>Use free online recipe collections and e-books tailored for budget cooking that can help you design your Christmas menu to meet your budget. This <a href="https://nomoneynotime.com.au/uploads/Our-Guide-to-the-Perfect-Christmas-Feast.pdf">one</a> was created by a group of <a href="https://dietitiansaustralia.org.au/working-dietetics/standards-and-scope/role-accredited-practising-dietitian">accredited practising dietitians</a> and has healthy, budget friendly recipes and ideas. You could also try this budget friendly collection of Christmas recipes from <a href="https://www.taste.com.au/recipes/collections/budget-christmas-recipes">taste</a>.</p> <p><strong>3. Involve the family</strong></p> <p>Get together with other family members and make it a challenge to see who can make the cheapest, most delicious dish. Get the kids involved in fun activities, such as making a DIY gingerbread house or putting together mixed skewers for the barbecue.</p> <p><strong>4. Pool your resources</strong></p> <p>Larger quantities of a single dish will be cheaper than multiple different dishes (and easier to prepare).</p> <p><strong>5. Frozen is fine</strong></p> <p>Use frozen fruits and vegetables if you need to. These can have just as <a href="https://pubmed.ncbi.nlm.nih.gov/25526594/">many vitamins and minerals</a> as fresh, are often cheaper than fresh produce and last longer. Try using frozen berries to decorate the pavlova or add them to your favourite cake, muffin or pie.</p> <p><strong>6. Make your own drinks</strong></p> <p>You could make your own drinks, such as home-brewed iced tea. See if anyone in your family has a soda stream you can borrow to make sparkling mineral water. Add some freshly squeezed lemon or lime for extra flavour.</p> <p><strong>7. Reduce waste</strong></p> <p>Use your own crockery and re-use leftovers to reduce waste. After all, washing up is cheaper than buying plastic or paper plates and better for the environment. Remember to save any leftovers and re-use them. Leftover fresh vegetables could be used to make a hearty soup or chutney.</p> <h2>It doesn’t have to be perfect</h2> <p>Christmas comes and goes quickly. If your cooking ideas don’t work out, it’s not the end of the world. Choosing healthy foods on a budget is important all year around, so you may like to think about trying these tips throughout the years to come. <img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/196565/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/lauren-ball-14718"><em>Lauren Ball</em></a><em>, Professor of Community Health and Wellbeing, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a>; <a href="https://theconversation.com/profiles/amy-kirkegaard-1401256">Amy Kirkegaard</a>, Postdoctoral Research Fellow, School of Human Movement and Nutrition Sciences, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a>; <a href="https://theconversation.com/profiles/breanna-lepre-1401257">Breanna Lepre</a>, Research Fellow, Mater Research Institute, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a>, and <a href="https://theconversation.com/profiles/emily-burch-438717">Emily Burch</a>, Dietitian and Researcher, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a></em></p> <p><em>Image credits: Getty Images</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

How to make the perfect pavlova, according to chemistry experts

<p><em><a href="https://theconversation.com/profiles/nathan-kilah-599082">Nathan Kilah</a>, <a href="https://theconversation.com/institutions/university-of-tasmania-888">University of Tasmania</a> and <a href="https://theconversation.com/profiles/chloe-taylor-1400788">Chloe Taylor</a>, <a href="https://theconversation.com/institutions/university-of-tasmania-888">University of Tasmania</a></em></p> <p>The pavlova is a summer icon; just a few simple ingredients can be transformed into a beautifully flavoured and textured dessert.</p> <p>But despite its simplicity, there’s a surprising amount of chemistry involved in making a pavlova. Knowing what’s happening in each step is a sure-fire way to make yours a success.</p> <p>So exactly what does it take to make the perfect pavlova? Let us break it down for you.</p> <h2>Egg whites</h2> <p><a href="https://theconversation.com/eight-cracking-facts-about-eggs-150797">Egg white</a> is basically a mixture of proteins in water. Two of these proteins, ovalbumin and ovomucin, are the key to forming a perfect foamy meringue mixture.</p> <p>Whipping the egg whites agitates the proteins and disrupts their structure, causing them to unfold so the protein’s interior surface is exposed, in a process <a href="https://theconversation.com/sunny-side-up-can-you-really-fry-an-egg-on-the-footpath-on-a-hot-day-172616">known as denaturing</a>. These surfaces then join with one another to trap air bubbles and turn into a stable foam.</p> <p>Egg yolk must be completely removed for this process to work. Yolk is mostly made of fat molecules, which would destabilise the protein network and pop the air bubbles. It only takes a trace amount of fat, or even just a greasy bowl, to disrupt foam formation.</p> <p>You should always whip your egg whites in a clean glass or metal bowl. Plastic bowls are more likely to hold leftover grease.</p> <h2>Sugar</h2> <p>A traditional pavlova uses sugar – a lot of it – to provide texture and flavour. The ratio of sugar to egg white will differ between recipes.</p> <p>The first thing to remember is that adding more sugar will give you a drier and crispier texture, whereas less sugar will lead to a softer and chewier pavlova that won’t keep as long.</p> <p>The second thing is the size of the sugar crystals. The larger they are, the longer they’ll need to be whipped to dissolve, and the greater the chance you will overwork the proteins in your meringue. Powdered icing sugar (not icing mixture) is preferable to caster or granulated sugar.</p> <p>If you do happen to overbeat your meringue (which may end up looking clumpy and watery) you can try to save it by adding another egg white.</p> <h2>Acid</h2> <p>Many pavlova recipes call for adding cream of tartar or vinegar. Cream of tartar is also known as potassium hydrogen tartrate, which you may have seen in the form of crystals at the <a href="https://theconversation.com/louis-pasteurs-scientific-discoveries-in-the-19th-century-revolutionized-medicine-and-continue-to-save-the-lives-of-millions-today-191395">bottom of a wine glass</a>.</p> <p>These acids act as a stabilising agent for the meringue by aiding in the unfolding of the egg white proteins. More isn’t always better, though. Using too much stabiliser can affect the taste and texture, so use it sparingly.</p> <h2>Heat</h2> <p>Cooking a pavlova requires a very slow oven for specific chemical reasons. Namely, egg white proteins gel at temperatures above 60°C, setting the meringue.</p> <p>At higher temperatures a chemical reaction known as the <a href="https://theconversation.com/kitchen-science-from-sizzling-brisket-to-fresh-baked-bread-the-chemical-reaction-that-makes-our-favourite-foods-taste-so-good-58577">Maillard reaction</a> takes place in which proteins and sugars react to form new flavourful compounds. We can thank the Maillard reaction for many delicious foods including <a href="https://theconversation.com/brewing-a-great-cup-of-coffee-depends-on-chemistry-and-physics-84473">roasted coffee</a>, toast and <a href="https://theconversation.com/what-makes-smoky-charred-barbecue-taste-so-good-the-chemistry-of-cooking-over-an-open-flame-184206">seared steak</a>.</p> <p>However, excessive Maillard reactions are undesirable for a pavlova. An oven that’s too hot will turn your meringue brown and give it a “caramelised” flavour. Recipes calling for pavlova to be left in the oven overnight may actually overcook it.</p> <p>At the same time, you don’t want to accidentally undercook your pavlova – especially since uncooked eggs are often responsible for <a href="https://theconversation.com/how-to-avoid-food-borne-illness-a-nutritionist-explains-153185">food poisoning</a>. To kill dangerous bacteria, including salmonella, the pavlova’s spongy centre must reach <a href="https://foodsafety.asn.au/eggs/">temperatures above 72°C</a>.</p> <p>An alternative is to use pasteurised egg whites, which are briefly heated to a very high temperature to kill any pathogens. But this processing may also affect the egg white’s whippability.</p> <h2>Substitute ingredients</h2> <p>People love pavlova, and nobody should have to miss out. Luckily they don’t have to.</p> <p>If you want to <a href="https://theconversation.com/a-taste-for-sweet-an-anthropologist-explains-the-evolutionary-origins-of-why-youre-programmed-to-love-sugar-173197">limit your sugar intake</a>, you can make your meringue using sweeteners such as <a href="https://theconversation.com/whats-the-difference-between-sugar-other-natural-sweeteners-and-artificial-sweeteners-a-food-chemist-explains-sweet-science-172571">powdered erythritol or monk fruit</a>. But, if you do, you may want to add some extra stabiliser such as cornflour, arrowroot starch, or a pinch of xanthan gum to maintain the classic texture.</p> <p>Also, if you want a vegan pavlova, you can turn to the chickpea instead of the chicken! <a href="https://review.jove.com/t/56305/composition-properties-aquafaba-water-recovered-from-commercially">Aquafaba</a> – the water collected from tinned or soaked beans – contains proteins and carbohydrates that give it emulsifying, foaming and even thickening properties. Egg-free pavlova recipes typically replace one egg white with about two tablespoons of aquafaba.</p> <p>And for those of you who don’t do gluten, pavlova can easily be made <a href="https://theconversation.com/gluten-free-diet-is-expensive-socially-challenging-for-those-with-celiac-disease-and-wheat-allergy-155861">gluten-free</a> by using certain stabilising agents.</p> <p>All that’s left is to get creative with your toppings and decide what to do with those leftover yolks!<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/196485/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/nathan-kilah-599082"><em>Nathan Kilah</em></a><em>, Senior Lecturer in Chemistry, <a href="https://theconversation.com/institutions/university-of-tasmania-888">University of Tasmania</a> and <a href="https://theconversation.com/profiles/chloe-taylor-1400788">Chloe Taylor</a>, Research Fellow - PhD candidate, <a href="https://theconversation.com/institutions/university-of-tasmania-888">University of Tasmania</a></em></p> <p><em>Image credits: Getty Images</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.
