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.

Mothers’ dieting habits and self-talk have profound impact on daughters − 2 psychologists explain how to cultivate healthy behaviors and body image

<p><em><a href="https://theconversation.com/profiles/janet-j-boseovski-451496">Janet J. Boseovski</a>, <a href="https://theconversation.com/institutions/university-of-north-carolina-greensboro-2069">University of North Carolina – Greensboro</a> and <a href="https://theconversation.com/profiles/ashleigh-gallagher-1505989">Ashleigh Gallagher</a>, <a href="https://theconversation.com/institutions/university-of-north-carolina-greensboro-2069">University of North Carolina – Greensboro</a></em></p> <p>Weight loss is one of the most common health and appearance-related goals.</p> <p>Women and <a href="https://www.cdc.gov/nchs/products/databriefs/db340.htm">teen girls</a> are <a href="https://www.cdc.gov/nchs/products/databriefs/db313.htm">especially likely to pursue dieting</a> to achieve weight loss goals even though a great deal of research shows that <a href="https://theconversation.com/what-thin-people-dont-understand-about-dieting-86604">dieting doesn’t work over the long term</a>.</p> <p>We are a <a href="https://www.duck-lab.com/people">developmental psychologist</a> and a <a href="https://psy.uncg.edu/directory/ashleigh-gallagher/">social psychologist</a> who together wrote a forthcoming book, “Beyond Body Positive: A Mother’s Evidence-Based Guide for Helping Girls Build a Healthy Body Image.”</p> <p>In the book, we address topics such as the effects of maternal dieting behaviors on daughters’ health and well-being. We provide information on how to build a foundation for healthy body image beginning in girlhood.</p> <h2>Culturally defined body ideals</h2> <p>Given the strong influence of social media and other cultural influences on body ideals, it’s understandable that so many people pursue diets aimed at weight loss. <a href="https://communityhealth.mayoclinic.org/featured-stories/tiktok-diets">TikTok</a>, YouTube, Instagram and celebrity websites feature slim influencers and “how-tos” for achieving those same results in no time.</p> <p>For example, women and teens are engaging in rigid and extreme forms of exercise such as 54D, a program to <a href="https://54d.com/">achieve body transformation in 54 days</a>, or the <a href="https://health.clevelandclinic.org/75-hard-challenge-and-rules">75 Hard Challenge</a>, which is to follow five strict rules for 75 days.</p> <p>For teens, these pursuits are likely fueled by trendy body preoccupations such as the desire for “<a href="https://www.nytimes.com/2024/02/06/well/move/tiktok-legging-legs-eating-disorders.html">legging legs</a>.”</p> <p>Women and teens have also been been inundated with recent messaging around <a href="https://theconversation.com/drugs-that-melt-away-pounds-still-present-more-questions-than-answers-but-ozempic-wegovy-and-mounjaro-could-be-key-tools-in-reducing-the-obesity-epidemic-205549">quick-fix weight loss drugs</a>, which come with a lot of caveats.</p> <p>Dieting and weight loss goals are highly individual, and when people are intensely self-focused, it is <a href="https://doi.org/10.1521/jscp.2000.19.1.70">possible to lose sight of the bigger picture</a>. Although women might wonder what the harm is in trying the latest diet, science shows that dieting behavior doesn’t just affect the dieter. In particular, for women who are mothers or who have other girls in their lives, these behaviors affect girls’ emerging body image and their health and well-being.</p> <h2>The profound effect of maternal role models</h2> <p>Research shows that mothers and maternal figures <a href="https://doi.org/10.1016/j.brat.2017.11.001">have a profound influence on their daughters’ body image</a>.</p> <p>The opportunity to influence girls’ body image comes far earlier than adolescence. In fact, research shows that these influences on body image <a href="https://www.teenvogue.com/story/how-toxic-diet-culture-is-passed-from-moms-to-daughters">begin very early in life</a> – <a href="https://doi.org/10.1016/bs.acdb.2016.10.006">during the preschool years</a>.</p> <p>Mothers may feel that they are being discreet about their dieting behavior, but little girls are watching and listening, and they are far more observant of us than many might think.</p> <p>For example, one study revealed that compared with daughters of nondieting women, 5-year-old girls whose mothers dieted <a href="https://doi.org/10.1016/S0002-8223(00)00339-4">were aware of the connection between dieting and thinness</a>.</p> <p>Mothers’ eating behavior does not just affect girls’ ideas about dieting, but also their daughters’ eating behavior. The amount of food that mothers eat <a href="https://doi.org/10.1016/j.appet.2018.04.018">predicts how much their daughters will eat</a>. In addition, daughters whose mothers are dieters are <a href="https://doi.org/10.1016/j.appet.2018.04.018">more likely to become dieters themselves</a> and are also <a href="https://doi.org/10.1016/j.eatbeh.2007.03.001">more likely to have a negative body image</a>.</p> <p>Negative body image is <a href="https://theconversation.com/mounting-research-documents-the-harmful-effects-of-social-media-use-on-mental-health-including-body-image-and-development-of-eating-disorders-206170">not a trivial matter</a>. It affects girls’ and women’s mental and physical well-being in a <a href="https://doi.org/10.1177/1359105317710815">host of ways</a> and <a href="https://doi.org/10.1016/j.brat.2011.06.009">can predict the emergence of eating disorders</a>.</p> <h2>Avoiding ‘fat talk’</h2> <p>What can moms do, then, to serve their daughters’ and their own health?</p> <p>They can focus on small steps. And although it is best to begin these efforts early in life – in girlhood – it is never too late to do so.</p> <p>For example, mothers can consider how they think about and talk about themselves around their daughters. Engaging in “fat talk” may inadvertently send their daughters the message that larger bodies are bad, <a href="https://doi.org/10.1016/j.bodyim.2020.07.004">contributing to weight bias</a> and negative self-image. Mothers’ fat talk also <a href="https://doi.org/10.1080/15267431.2021.1908294">predicts later body dissatisfaction in daughters</a>.</p> <p>And negative self-talk isn’t good for mothers, either; it is associated with <a href="https://doi.org/10.1177/1359105318781943">lower motivation and unhealthful eating</a>. Mothers can instead practice and model self-compassion, which involves treating oneself the way <a href="https://doi.org/10.1016/j.bodyim.2016.03.003">a loving friend might treat you</a>.</p> <p>In discussions about food and eating behavior, it is important to avoid moralizing certain kinds of food by labeling them as “good” or “bad,” as girls may extend these labels to their personal worth. For example, a young girl may feel that she is being “bad” if she eats dessert, if that is what she has learned from observing the women around her. In contrast, she may feel that she has to eat a salad to be “good.”</p> <p>Moms and other female role models can make sure that the dinner plate sends a healthy message to their daughters by showing instead that all foods can fit into a balanced diet when the time is right. Intuitive eating, which emphasizes paying attention to hunger and satiety and allows flexibility in eating behavior, is associated with <a href="https://doi.org/10.1007/s40519-020-00852-4">better physical and mental health in adolescence</a>.</p> <p>Another way that women and especially moms can buffer girls’ body image is by helping their daughters <a href="https://doi.org/10.1016/j.bodyim.2021.12.009">to develop media literacy</a> and to think critically about the nature and purpose of media. For example, moms can discuss the misrepresentation and distortion of bodies, such as the use of filters to enhance physical appearance, on social media.</p> <h2>Focusing on healthful behaviors</h2> <p>One way to begin to focus on health behaviors rather than dieting behaviors is to develop respect for the body and to <a href="https://theconversation.com/body-neutrality-what-it-is-and-how-it-can-help-lead-to-more-positive-body-image-191799">consider body neutrality</a>. In other words, prize body function rather than appearance and spend less time thinking about your body’s appearance. Accept that there are times when you may not feel great about your body, and that this is OK.</p> <p>To feel and look their best, mothers can aim to stick to a <a href="https://theconversation.com/whats-the-best-diet-for-healthy-sleep-a-nutritional-epidemiologist-explains-what-food-choices-will-help-you-get-more-restful-zs-219955">healthy sleep schedule</a>, manage their stress levels, <a href="https://theconversation.com/fiber-is-your-bodys-natural-guide-to-weight-management-rather-than-cutting-carbs-out-of-your-diet-eat-them-in-their-original-fiber-packaging-instead-205159">eat a varied diet</a> that includes all of the foods that they enjoy, and <a href="https://theconversation.com/the-runners-high-may-result-from-molecules-called-cannabinoids-the-bodys-own-version-of-thc-and-cbd-170796">move and exercise their bodies regularly</a> as lifelong practices, rather than engaging in quick-fix trends.</p> <p>Although many of these tips sound familiar, and perhaps even simple, they become effective when we recognize their importance and begin acting on them. Mothers can work toward modeling these behaviors and tailor each of them to their daughter’s developmental level. It’s never too early to start.</p> <h2>Promoting healthy body image</h2> <p>Science shows that several personal characteristics are associated with body image concerns among women.</p> <p>For example, research shows that women who are <a href="https://doi.org/10.1016/j.bodyim.2020.02.001">higher in neuroticism</a> <a href="https://doi.org/10.1186/2050-2974-1-2">and perfectionism</a>, <a href="https://doi.org/10.3389/fpsyg.2022.983534">lower in self-compassion</a> or <a href="https://doi.org/10.1016/j.bodyim.2013.08.001">lower in self-efficacy</a> are all more likely to struggle with negative body image.</p> <p>Personality is frequently defined as a person’s characteristic pattern of thoughts, feelings and behaviors. But if they wish, <a href="https://doi.org/10.1002/per.1945">mothers can change personality characteristics</a> that they feel aren’t serving them well.</p> <p>For example, perfectionist tendencies – such as setting unrealistic, inflexible goals – can be examined, challenged and replaced with more rational thoughts and behaviors. A woman who believes she must work out every day can practice being more flexible in her thinking. One who thinks of dessert as “cheating” can practice resisting moral judgments about food.</p> <p>Changing habitual ways of thinking, feeling and behaving certainly takes effort and time, but it is far more likely than diet trends to bring about sustainable, long-term change. And taking the first steps to modify even a few of these habits can positively affect daughters.</p> <p>In spite of all the noise from media and other cultural influences, mothers can feel empowered knowing that they have a significant influence on their daughters’ feelings about, and treatment of, their bodies.</p> <p>In this way, mothers’ modeling of healthier attitudes and behaviors is a sound investment – for both their own body image and that of the girls they love.<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/221968/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/janet-j-boseovski-451496"><em>Janet J.

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>

Globally, millions of people <a href="https://doi.org/10.1111%2Fobr.12466">attempt to lose weight</a> every year with the hope that weight loss will have positive effects on their body image, health and quality of life.</p> <p>However, these motivated individuals often struggle to maintain new diets or exercise regimens. The rise of medications such as semaglutides, like <a href="https://dhpp.hpfb-dgpsa.ca/dhpp/resource/101298">Ozempic</a> or <a href="https://dhpp.hpfb-dgpsa.ca/dhpp/resource/101765">Wegovy</a>, <a href="https://www.cbc.ca/news/health/ozempic-weight-loss-1.6772021">might be viewed as an appealing “quick fix”</a> alternative to meet weight loss goals.</p> <p>Research led by our team and others suggests that such attempts to lose weight often do more harm than good, and even increase the risk of <a href="https://osf.io/9stq2">developing an eating disorder</a>.</p> <h2>Weight loss and eating disorders</h2> <p>Eating disorders are <a href="https://doi.org/10.1002/eat.20589">serious mental health conditions</a> primarily characterized by extreme patterns of under- or over-eating, concerns about one’s shape or body weight or other behaviours intended to influence body shape or weight such as exercising excessively or self-inducing vomiting.</p> <p>Although once thought to only affect young, white adolescent girls, eating disorders do not discriminate; eating disorders can develop in people of <a href="https://doi.org/10.1002/erv.2553">any age, sex, gender or racial/ethnic background</a>, with an estimated <a href="https://nedic.ca/general-information/">one million Canadians</a> suffering from an eating disorder at any given time. Feb. 1 to 7 is <a href="https://nedic.ca/edaw/">National Eating Disorders Awareness Week</a>.</p> <p>As a clinical psychologist and clinical psychology graduate student, our research has focused on how eating disorders develop and what keeps them going. Pertinent to society’s focus on weight-related goals, our research has examined associations between weight loss and eating disorder symptoms.</p> <h2>Eating disorders and ‘weight suppression’</h2> <p>In eating disorders research, the state of maintaining weight loss is referred to as “weight suppression.” Weight suppression is typically defined as the difference between a person’s current weight and their highest lifetime weight (excluding pregnancy).</p> <p>Despite the belief that weight loss will improve body satisfaction, we found that in a sample of over 600 men and women, weight loss had no impact on women’s negative body image and was associated with increased body dissatisfaction in <a href="https://doi.org/10.1016/j.bodyim.2023.01.011">men</a>. Importantly, being more weight suppressed has been associated with the <a href="https://doi.org/10.1093/ajcn/nqaa146">onset of eating disorders</a>, including anorexia nervosa and bulimia nervosa.</p> <p><a href="https://doi.org/10.1007/s11920-018-0955-2">One proposed explanation</a> for the relationship between weight suppression and eating disorders is that maintaining weight loss becomes increasingly difficult as body systems that <a href="https://doi.org/10.3945/ajcn.110.010025">reduce metabolic rate and energy expenditure, and increase appetite</a>, are activated to promote weight gain.</p> <p>There is growing awareness that <a href="https://doi.org/10.1136/bmj.g2646">weight regain is highly likely following conventional diet programs</a>. This might lead people to engage in more and more extreme behaviours to control their weight, or they might shift between extreme restriction of food intake and episodes of overeating or binge eating, the characteristic symptoms of bulimia nervosa.</p> <h2>Ozempic and other semaglutide drugs</h2> <p>Semaglutide drugs like Ozempic and Wegovy are part of a class of drug called <a href="https://pdf.hres.ca/dpd_pm/00067924.PDF">glucagon-like peptide-1 agonists (GLP-1As)</a>. These drugs work by mimicking the hormone GLP-1 to interact with neural pathways that signal satiety (fullness) and slow stomach emptying, leading to reduced food intake.</p> <p>Although GLP-1As are indicated to treat Type 2 diabetes, <a href="https://www.cbc.ca/news/canada/london/ozempic-off-label-1.6884141">they are increasingly prescribed off-label</a> or being <a href="https://www.bbc.com/news/health-67414203">illegally purchased</a> without a prescription because of their observed effectiveness at inducing weight loss. Although medications like Ozempic do often lead to weight loss, the rate of weight loss may <a href="https://doi.org/10.1001/jama.2021.3224">slow down or stop over time</a>.</p> <p>Research by Lindsay Bodell, one of the authors of this story, and her colleagues on weight suppression may help explain why effects of semaglutides diminish over time, as <a href="https://doi.org/10.1016/j.physbeh.2019.112565">weight suppression is associated with reduced GLP-1 response</a>. This means those suppressing their weight could become less responsive to the satiety signals activated by GLP-1As.</p> <p>Additionally, weight loss effects are only seen for as long as the medication is taken, meaning those who take these drugs to achieve some weight loss goal are <a href="https://doi.org/10.1111/dom.14725">likely to regain most, if not all, weight lost</a> when they stop taking the medication.</p> <h2>Risks of dieting and weight-loss drugs</h2> <p>The growing market for off-label weight loss drugs is concerning, because of the exacerbation of <a href="https://theconversation.com/ozempic-the-miracle-drug-and-the-harmful-idea-of-a-future-without-fat-211661">weight stigma</a> and the serious <a href="https://doi.org/10.1016/j.jand.2022.01.004">health risks</a> associated with unsupervised weight loss, including developing eating disorders.</p> <p>Researchers and health professionals are already raising the alarm about the use of GLP-1As in children and adolescents, due to concerns about their possible <a href="https://doi.org/10.1017/cts.2023.612">impact on growth and development</a>.</p> <p>Moreover, popular weight-loss methods, whether they involve pills or “crash diets,” often mimic symptoms of eating disorders. For example, intermittent fasting diets that involve long periods of fasting followed by short periods of food consumption may mimic and <a href="https://doi.org/10.1016/j.eatbeh.2022.101681">increase the risk of developing binge eating problems</a>.</p> <p>The use of diet pills or laxatives to lose weight has been found to increase the risk of <a href="https://doi.org/10.2105/AJPH.2019.305390">being diagnosed with an eating disorder in the next one to three years</a>. Drugs like Ozempic may also be <a href="https://doi.org/10.1002/eat.24109">misused by individuals already struggling with an eating disorder</a> to suppress their appetite, compensate for binge eating episodes or manage fear of weight gain.</p> <p>Individuals who are already showing signs of an eating disorder, such as limiting their food intake and intense concerns about their weight, may be most at risk of spiralling from a weight loss diet or medication into an eating disorder, <a href="https://doi.org/10.1002/eat.24116">even if they only lose a moderate amount of weight</a>.</p> <p>People who are dissatisfied with their weight or have made multiple attempts to lose weight often feel pressured to try increasingly drastic methods. However, any diet, exercise program or weight-loss medication promising a quick fix for weight loss should be treated with extreme caution. At best, you may gain the weight back; at worst, you put yourself at risk for much more serious eating disorders and other health problems.<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/221514/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/samantha-withnell-1504436"><em>Samantha Withnell</em></a><em>, PhD Candidate, Clinical Psychology, <a href="https://theconversation.com/institutions/western-university-882">Western University</a> and <a href="https://theconversation.com/profiles/lindsay-bodell-1504260">Lindsay Bodell</a>, Assistant Professor of Psychology, <a href="https://theconversation.com/institutions/western-university-882">Western 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.

Is your diet giving you headaches?

<p><strong>Diet-induced headaches</strong></p> <p>If you’re searching for the cause of that niggling headache, it’s possible that what you’re eating – or drinking – could be to blame.</p> <p><strong>Stop over-restricting your kilojoule intake</strong></p> <p>Spacing your meals too far apart or eating at irregular intervals causes a dip in blood-glucose levels, which drives your body into starvation mode. This triggers a cascade of hormones and brain chemicals similar to your body’s response to stress, which can bring on headaches. Once you fuel up, the headache should go away.</p> <p><span style="text-decoration: underline;"><em>Tip:</em></span> You should wait no more than four hours between meals. Try light snacks between meals, such as a handful of almonds.</p> <p><strong>Stay hydrated </strong></p> <p>Dehydration is a common headache trigger. Experts suspect it may have to do with narrowing of blood vessels in the brain, which reduces the brain’s supply of blood and oxygen. Not getting sufficient electrolytes may also contribute to headaches.</p> <p><span style="text-decoration: underline;"><em>Tip:</em></span> By the time you feel thirsty, your body is already a little dehydrated, so rehydrate often. Have a glass of water with every meal and between meals.</p> <p><strong>Avoid artificial sweeteners</strong></p> <p>Some people may be particularly sensitive to aspartame, which can lead to headaches, according to a US study. Aspartame can be in diet drinks as well as foods.</p> <p><span style="text-decoration: underline;"><em>Tip:</em></span> If you suspect artificial sweeteners may be triggering your headaches, keep a food journal to watch for patterns.</p> <p><strong>Cut caffeine slowly</strong></p> <p>If you’ve ditched fizzy drinks or coffee, you may be experiencing caffeine withdrawal. Experts estimate that about half of people who cut back on caffeine experience headaches.</p> <p><span style="text-decoration: underline;"><em>Tip:</em></span> Decrease your caffeine intake gradually.</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/your-diet-giving-you-headaches" target="_blank" rel="noopener">Reader's Digest</a>. </em></p>

When it comes to weight, your ‘diet’ is much more than what you eat

<p>Atkins, keto, palaeo, gluten-free, low-carb, low-fat, high-fat, raw, vegan, vego, pescatarian – phew, that’s a lot of different diets!</p> <div class="copy"> <p>And it’s by no means an exhaustive list.</p> <p>The old adage ‘you are what you eat’ has come to be a mantra for good diet and health. It was originally coined by 19th-century German philosopher Ludwig Feuerbach, himself drawing on commentary by an earlier French gourmand Anthelme Brillat-Savarin.</p> <p>Increasingly, science is finding new connections between diet and our overall picture of health. You may have heard how our gut microbiome acts as a second brain, or that avoiding unprocessed foods can lead to all-cause mortality.</p> <p>But when it comes to many fad diets that promise quick weight loss or improved health, the science can sometimes be skimp. This can change over time as researchers test the influence of diet on general health, weight management and as a medical treatment.</p> <p>The <a href="https://cosmosmagazine.com/health/mediterranean-diet-heart-dementia/">Mediterranean diet</a> is probably closest to the mark as a lifestyle of choice, in terms of overall health, nutrition, and diet science. It emphasises <a href="https://cosmosmagazine.com/health/nutrition/plant-based-diets-could-prevent-type-2-diabetes/">fruit and vegetable</a> consumption, with some wholegrain breads and cereals, legumes, nuts, seeds and fish, with olive oil as a primary fat source.</p> <p>This diet is either explicitly endorsed by many health authorities around the world such as the <a href="https://www.heart.org/en/healthy-living/healthy-eating/eat-smart/nutrition-basics/mediterranean-diet" target="_blank" rel="noreferrer noopener">American Heart Association</a>, the <a href="https://www.racgp.org.au/clinical-resources/clinical-guidelines/handi/handi-interventions/nutrition/mediterranean-diet-for-reducing-cardiovascular-dis" target="_blank" rel="noreferrer noopener">Royal Australian College of General Practitioners</a> as a diet for lowering cardiovascular disease risk, or used as a basis for other recommendations. The World Health Organization also <a href="https://www.who.int/europe/news/item/07-05-2018-fostering-healthier-and-more-sustainable-diets-learning-from-the-mediterranean-and-new-nordic-experience" target="_blank" rel="noreferrer noopener">advises</a> on ways for the Mediterranean and similar New Nordic diets to be implemented as <a href="https://iris.who.int/bitstream/handle/10665/326264/9789289053013-eng.pdf?sequence=3" target="_blank" rel="noreferrer noopener">health policy</a>.</p> <p>But diet might be better considered about more than what goes in one’s mouth.</p> <p>Dr Evangeline Mantzioris, Program Director of the Nutrition and Food Sciences Degree at the University of South Australia, says a truer interpretation of the world extends beyond merely food and drink.</p> <p>“The word diet actually derives from the Greek word <em>diaita</em>, which means the way you choose to live your life,” Mantzioris told the <a href="https://cosmosmagazine.com/tag/debunks/" target="_blank" rel="noreferrer noopener"><em>Debunks</em> podcast.</a></p> <p>“So it’s not just about the food, it’s about the exercise, it’s about the social interaction, it’s about the rest. It’s about the sleep. It’s all of that.”</p> <p>The WHO’s 2019 Health Evidence Network Synthesis Report also acknowledges both social and sleep components of the lifestyle, noting shared eating practices, post-meal siestas and lengthy meal times all contribute to positive health effects.</p> <p>In terms of the nutritional component, Mantzioris notes that adherence to the diet requires not just an uptake of olive oil, but cutting down on less beneficial foods and an active lifestyle.</p> <p>“It’s not just the olive oil, it’s dropping down the meat, it’s mainly a plant food diet, it’s purposeful exercise,” she says.</p> <p>“I’m always a little bit nervous when people just talk about the diet and the food without considering the rest of it.</p> <p>“In the 60s, when the health benefits of the Mediterranean diet were seen […] they were out there harvesting, growing their food, preparing their food, doing all that sort of purposeful exercise in the outdoor environment, often in quite steep terrain. So that is just as important.</p> <p>“The Mediterranean diet continues to be shown to be quite healthy and beneficial in terms of improving chronic disease risk, even without weight loss.”</p> <p>Mantzioris says that the diet has also been shown to improve cognitive and mental health outcomes.</p> <p>Diet is the focus of the latest episode of <em>Debunks</em> from Cosmos and 9Podcasts, where we dive not simply into what makes a good diet, but the principles that dieticians and nutritionists look for when recommending one for a patient to consider.</p> <p><iframe title="Weight: Do diets actually work?" src="https://omny.fm/shows/debunks/weight-do-diets-actually-work/embed?style=Artwork" width="100%" height="180" frameborder="0"></iframe> <!-- Start of tracking content syndication.

What is the OMAD diet? Is one meal a day actually good for weight loss? And is it safe?

<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>What do British Prime Minister <a href="https://www.sciencefocus.com/the-human-body/one-meal-a-day-diet-omad">Rishi Sunak</a> and singer <a href="https://theconversation.com/one-meal-a-day-diet-popular-with-celebrities-could-do-more-harm-than-good-heres-why-203086">Bruce Springsteen</a> have in common?</p> <p>They’re among an ever-growing group of public figures touting the benefits of eating just one meal a day.</p> <p>As a result, the one meal a day (OMAD) diet is the latest attention-grabbing weight loss trend. Advocates claim it leads to fast, long-term weight loss success and better health, including delaying the ageing process.</p> <p>Like most weight-loss programs, the OMAD diet makes big and bold promises. Here’s what you need to know about eating one meal a day and what it means for weight loss.</p> <h2>The OMAD diet explained</h2> <p>Essentially, the OMAD diet is a type of intermittent fasting, where you fast for 23 hours and consume all your daily calories in one meal eaten within one hour.</p> <p>The OMAD diet rules are presented as simple and easy to follow:</p> <ol> <li> <p>You can eat whatever you want, provided it fits on a standard dinner plate, with no calorie restrictions or nutritional guidelines to follow.</p> </li> <li> <p>You can drink calorie-free drinks throughout the day (water, black tea and coffee).</p> </li> <li> <p>You must follow a consistent meal schedule, eating your one meal around the same time each day.</p> </li> </ol> <p>Along with creating a calorie deficit, resulting in weight loss, advocates believe the OMAD diet’s extended fasting period <a href="https://www.frontiersin.org/articles/10.3389/fphys.2021.771944/full">leads to physiological changes</a> in the body that promote better health, including boosting your metabolism by triggering a process called ketosis, where your body burns stored fat for energy instead of glucose.</p> <h2>What does the evidence say?</h2> <p>Unfortunately, research into the OMAD diet is limited. Most studies have examined its impact on <a href="https://www.cell.com/cell-metabolism/pdf/S1550-4131(18)30512-6.pdf">animals</a>, and the <a href="https://pubmed.ncbi.nlm.nih.gov/35087416/">primary study</a> with humans involved 11 lean, young people following the OMAD diet for a mere 11 days.</p> <p>Claims about the OMAD diet typically rely on research into intermittent fasting, rather than on the OMAD diet itself. There is <a href="https://www.cfp.ca/content/66/2/117.short">evidence</a> backing the efficacy of intermittent fasting to achieve weight loss. However, <a href="https://www.nature.com/articles/s41574-022-00638-x">most studies</a> have focused on short-term results only, typically considering the results achieved across 12 weeks or less.</p> <p>One <a href="https://www.nejm.org/doi/full/10.1056/NEJMoa2114833">longer-term study from 2022</a> randomly assigned 139 patients with obesity to either a calorie-restricted diet with time-restricted eating between 8am and 4pm daily, or to a diet with daily calorie restriction alone for 12 months.</p> <p>After 12 months, both groups had lost around the same weight and experienced similar changes in body fat, blood sugar, cholesterol and blood pressure. This indicates long-term weight loss achieved with intermittent fasting is not superior and on a par with that achieved by traditional dieting approaches (daily calorie restriction).</p> <h2>So what are the problems with the OMAD diet?</h2> <p><strong>1. It can cause nutritional deficiencies and health issues.</strong></p> <p>The OMAD diet’s lack of nutritional guidance on what to eat for that one meal a day raises many red flags.</p> <p>The meals we eat every day should include a source of protein balanced with wholegrain carbs, vegetables, fruits, protein and good fats to support <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7071223/">optimum health, disease prevention and weight management</a>.</p> <p>Not eating a balanced diet will result in nutritional deficiencies that can result in poor immune function, fatigue and a decrease in bone density, leading to osteoporosis.</p> <p>Fasting for 23 hours a day is also likely to lead to extreme feelings of hunger and uncontrollable cravings, which may mean you consistently eat foods that are not good for you when it’s time to eat.</p> <p><strong>2. It’s unlikely to be sustainable.</strong></p> <p>You might be able to stick with the OMAD diet initially, but it will wear thin over time.</p> <p>Extreme diets – especially ones prescribing extended periods of fasting – aren’t enjoyable, leading to feelings of deprivation and social isolation during meal times. It’s hard enough to refuse a piece of office birthday cake at the best of times, imagine how this would feel when you haven’t eaten for 23 hours!</p> <p>Restrictive eating can also lead to an unhealthy relationship with food, making it even harder to achieve and maintain a healthy weight.</p> <p><strong>3. Quick fixes don’t work.</strong></p> <p>Like other popular intermittent fasting methods, the OMAD diet appeals because it’s easy to digest, and the results appear fast.</p> <p>But the OMAD diet is just another fancy way of cutting calories to achieve a quick drop on the scales.</p> <p>As your weight falls, things will quickly go downhill when your <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4766925/">body activates its defence mechanisms</a> to defend your weight loss. In fact, it will regain weight – a response that stems from our hunter-gatherer ancestors’ need to survive periods of deprivation when food was scarce.</p> <h2>The bottom line</h2> <p>Despite the hype, the OMAD diet is unsustainable, and it doesn’t result in better weight-loss outcomes than its predecessors. Our old habits creep back in and we find ourselves fighting a cascade of physiological changes to ensure we regain the weight we lost.</p> <p>Successfully losing weight long-term comes down to:</p> <ul> <li> <p>losing weight in small manageable chunks you can sustain, specifically periods of weight loss, followed by periods of weight maintenance, and so on, until you achieve your goal weight</p> </li> <li> <p>making gradual changes to your lifestyle to ensure you form habits that last a lifetime.</p> </li> </ul> <p><em><a href="https://theconversation.com/profiles/nick-fuller-219993">Nick Fuller</a>, Charles Perkins Centre Research Program Leader, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of 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.

The happiness diet: 7 foods to boost your mood

<p><strong>Mood boosting foods worth adding to your shopping trolley</strong></p> <p>For decades, our culture has focused on the connection between healthy eating and physiological wellness – most of all, related to weight. But out of a pandemic that made mental health a hot topic, you might also be gaining an awareness that the food you eat can seriously affect your mind.</p> <p>Research published in The British Medical Journal says diet plays a major role in how both our body and our brain are feeling. Poor nutrition can contribute to depression, anxiety, aggression (there’s a reason the word “hangry” exists!). But improving your diet, and knowing the right foods to eat, may help your mental health.</p> <p>Dietitian and certified intuitive eating counsellor Rachel Engelhart says certain foods can support your body’s processes that are responsible for positive moods and strong energy levels. Here’s Engelhart’s list of the greatest mood-boosting foods.</p> <p><strong>Fatty fish</strong></p> <p>Seafood like salmon, mackerel and canned tuna are rich in omega-3 fatty acids, which are ‘healthy fats’ with benefits throughout your body – from your heart to your eyes – and your brain.</p> <p>“Omega-3 fatty acids are anti-inflammatory and have the ability to cross into the brain, having a direct effect on mood-regulating molecules and neurotransmitters there,” says registered dietitian Kelsey Lorencz. Research has consistently linked low levels of omega-3s with mood disorders like depression and anxiety – and, according to a review published in Frontiers in Physiology, most of us don’t get enough omega-3 fats in our diet.</p> <p><strong>Yoghurt</strong></p> <p>According to Lorencz, “The bacteria in your gut can actually produce feel-good neurotransmitters like serotonin and dopamine.”</p> <p>Research has identified a particular bacterium that may have a strong impact on triggering these chemicals: a strain called Lactobacillus. One study published in the journal Nature found that feeding our gut with this good bacteria – found naturally in foods like yoghurt, kefir, and sauerkraut – doesn’t just keep the blues at bay, it can increase our resilience in the face of stress.</p> <p><strong>Bananas</strong></p> <p>Bananas aren’t just shaped like a smile – they’re a mood-boosting powerhouse. That’s in part because they’re also high in vitamin B6, one nutrient behind the production of the ‘happiness hormone’ serotonin. Bananas contain prebiotic fibre, which, along with that Lactobacillus, are essential for gut health that promotes a happy brain.</p> <p><strong>Cottage cheese</strong></p> <p>“The amino acid L-tyrosine is needed to make dopamine and norepinephrine, two neurotransmitters that affect our mood and can easily become depleted,” Lorencz says. She points to high sources like soy products, chicken, fish, nuts, seeds, avocados and bananas. But cottage cheese has a whopping amount of this amino acid, along with a few other mood-boosters in its arsenal. It’s high in protein, which is essential for our body to make and use its mood-promoting hormones, Engelhart says. (This protein is casein protein, which our body absorbs more slowly, sustaining energy levels, and may contribute to elevated moods, according to ongoing research.)</p> <p>Cottage cheese also contains selenium, a mineral that Nutrients research has suggested may be linked with lower rates of depression.</p> <p><strong>Nuts and seeds</strong></p> <p>Magnesium is a mineral that supports our body’s energy production – and not getting enough can lead to irritability, anxiety, sleeplessness and agitation, says Lorencz. Nuts like almonds, walnuts, cashews and seeds like pumpkin, chia and sesame are great sources of this vital nutrient, as well as tryptophan, an amino acid associated with good moods.</p> <p>Nuts and seeds can also be great vegetarian sources of those crucial omega-3 fatty acids.</p> <p><strong>Oysters</strong></p> <p>The ages-old wives’ tale about oysters as aphrodisiacs is still out for debate, but oysters can elevate one’s mood. They pack the highest zinc content of any food – a nutrient that’s linked with anxiety and depression when we’re deficient, says Lorencz – and contain tyrosine, an amino acid that helps our body produce the ‘feel good’ hormone dopamine.</p> <p>That’s great news for the shellfish-loving set. However, if you aren’t a fan of oysters, you can get this one-two mood-boosting punch from food like eggs, nuts and legumes.</p> <p><strong>Your favourite treat</strong></p> <p>“Having a varied diet is the best way to set your body up to produce the ‘feel good’ hormones that it needs,” Engelhart says, adding an important point: while this nutritious balance is important, so is treating yourself to food you enjoy. “So many of my clients are hard on themselves and rather judgmental around their food choices, and it negatively impacts their mood,” she says. “Sprinkling our day with a delicious coffee, a yummy dessert, or one of our favourite restaurant meals is also an important way to positively impact our mental health.”</p> <p>And if you want to be strategic about that treat, reach for some dark chocolate. Chocolate contains natural serotonin, and 2022 research found that dark chocolate has prebiotic effects in our gut, supporting stronger mental health.</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/mental-health/the-happiness-diet-7-foods-to-boost-your-mood" target="_blank" rel="noopener">Reader's Digest</a>.</em></p>

9 signs you have inflammation in your body. Could an anti-inflammatory diet help?

<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> and <a href="https://theconversation.com/profiles/emily-burch-438717">Emily Burch</a>, <a href="https://theconversation.com/institutions/southern-cross-university-1160">Southern Cross University</a></em></p> <p>There is a lot of health buzz around the term “inflammation” right now. From new scientific <a href="https://medicalxpress.com/news/2023-07-inflammation-discovery-aging-age-related-diseases.html">discoveries</a> to <a href="https://people.com/health/gwyneth-paltrow-addresses-backlash-anti-inflammatory-diet/">celebrities</a> and social media influencers, it seems like everyone is talking about this important bodily process and its potential impact on our health.</p> <p>“<a href="https://www.nature.com/articles/s41574-018-0059-4">Inflammaging</a>” is a specific term you may also have seen. It’s an age-related increase in persistent, low-grade inflammation in blood and tissue, which is a strong risk factor for many conditions and diseases.</p> <p>So, can an anti-inflammatory diet help reduce inflammation? Let’s take a look.</p> <h2>What is inflammation?</h2> <p>When our body becomes injured or encounters an infection, it activates defence mechanisms to protect itself. It does this by instructing our cells to fight off the invader. This fighting process <a href="https://www.nature.com/articles/s41591-019-0675-0#citeas">causes inflammation</a>, which often presents as swelling, redness and pain.</p> <p>In the short-term, inflammation is a sign your body is healing, whether from a grazed knee or a cold.</p> <p>If inflammation persists for a longer time it’s called “chronic”. That can indicate a <a href="https://www.nature.com/articles/s41467-018-05800-6">health problem</a> such as <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3638313/">arthritis</a>, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6719998/#B2-ijms-20-03879">heart disease</a>, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6523054/">diabetes</a>, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3390758/">dementia</a> or other autoimmune disorders.</p> <p>The <a href="https://www.ncbi.nlm.nih.gov/books/NBK493173/">signs and symptoms</a> of chronic inflammation may be present from several months to years and include:</p> <ol> <li>persistent pain</li> <li>chronic fatigue or insomnia</li> <li>joint stiffness</li> <li>skin problems</li> <li>elevated blood markers (such as <a href="https://www.healthdirect.gov.au/c-reactive-protein-CRP-blood-test">C-reactive protein</a>)</li> <li>gastrointestinal issues (constipation, diarrhoea, acid reflux)</li> <li>depression, anxiety and mood disorders</li> <li>unintended weight gain or loss</li> <li>frequent colds or flu.</li> </ol> <h2>What role does diet play?</h2> <p>The relationship between food and inflammation is <a href="https://www.sciencedirect.com/science/article/pii/S0735109706013350">well recognised</a>. Overall, some food components may activate the immune system by producing pro-inflammatory cytokines (small proteins important in cell signaling) or reducing the production of anti-inflammatory cytokines.</p> <p>A “<a href="https://theconversation.com/clear-evidence-for-a-link-between-pro-inflammatory-diets-and-27-chronic-diseases-heres-how-you-can-eat-better-158451">pro-inflammatory diet</a>” may increase inflammation in the body over the long term. Such diets are usually low in fresh produce like fruits, vegetables and wholegrains, and high in commercially baked goods, fried foods, added sugars and red and processed meats.</p> <p>In contrast, an “<a href="https://academic.oup.com/ajcn/article/80/4/1029/4690355">anti-inflammatory</a>” diet is associated with less inflammation in the body. There is no single anti-inflammatory diet. Two well-recognised, evidence-backed examples are the Mediterranean diet and the Dietary Approaches to Stop Hypertension (DASH) diet.</p> <p>Anti-inflammatory diets typically include the following elements:</p> <p><strong>1. high in antioxidants.</strong> These compounds help the body fight free radicals or unstable atoms, that in high quantities are linked to illnesses such as cancer and heart disease. The best way to consume antioxidants is by eating lots of fruits and vegetables. Research shows frozen, dried and canned fruits and vegetables can be <a href="https://theconversation.com/frozen-and-tinned-foods-can-be-just-as-nutritious-as-fresh-produce-heres-how-201740">just as good as fresh</a></p> <p><strong>2. high in “healthy”, unsaturated fatty acids.</strong> Monounsaturated fats and omega-3-fatty acids are found in fish (sardines, mackerel, salmon and tuna), seeds, nuts, and plant-based oils (olive oil and flaxseed oil)</p> <p><strong>3. high in fibre and prebiotics.</strong> Carrots, cauliflower, broccoli and leafy greens are good sources of fibre. Prebiotics promote the growth of beneficial microorganisms in our intestines and can come from onions, leeks, asparagus, garlic, bananas, lentils and legumes</p> <p><strong>4. low in processed foods.</strong> These contain refined carbohydrates (pastries, pies, sugar-sweetened beverages, deep-fried foods and processed meats).</p> <h2>Rheumatoid arthritis, dementia, depression</h2> <p>There is mixed evidence for the role of anti-inflammatory diets in rheumatoid arthritis pain management. A recent <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8706441/">2021 systematic review</a> (where researchers carefully group and examine the available evidence on a topic) found eating an anti-inflammatory diet likely leads to significantly lower pain in people with rheumatoid arthritis when compared with other diets.</p> <p>However, the 12 studies included in the review had a high risk of bias – likely because people knew they were eating healthy foods – so the confidence in the evidence was low.</p> <p>Inflammation is strongly implicated in the development of neurodegenerative diseases like <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6486891/">Alzheimer’s disease and related dementia</a> and evidence suggests anti-inflammatory diets might help to protect the brain.</p> <p>A <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5015034/">2016 review</a> showed an anti-inflammatory diet may be protective against cognitive impairment and dementia, but that further large randomised controlled trials are needed. A <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8673721/">2021 study</a> followed 1,059 people for three years and observed their diet. They reported those with a greater pro-inflammatory diet had an increased risk of developing dementia.</p> <p>Inflammation has also been linked with mental health, with people eating a pro-inflammatory diet reporting more symptoms of <a href="https://pubmed.ncbi.nlm.nih.gov/31152670/">depression</a>. Diet is the fundamental element of <a href="https://www1.racgp.org.au/ajgp/2019/october/lifestyle-interventions-for-mental-health">lifestyle approaches</a> to managing anxiety and mental health.</p> <p>More broadly, a <a href="https://www.mdpi.com/2227-9059/9/8/922">2021 review paper</a> examined recent research related to anti-inflammatory diets and their effect on reducing inflammation associated with ageing. It found compounds commonly found in anti-inflammatory diets could help alleviate the inflammatory process derived from diseases and unhealthy diets.</p> <h2>What about turmeric?</h2> <p>A favourite on social media and vitamin shelves, turmeric is promoted as having anti-inflammatory benefits. These are linked to a specific compound called <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5388087/#:%7E:text=Curcuminoids%20are%20phenolic%20compounds%20commonly,several%20important%20functions%20of%20curcuminoids.">curcumin</a>, which gives turmeric its distinctive yellow colour.</p> <p>Research suggests curcumin might act as an anti-inflammatory agent in the body but high-quality clinical trials in humans are <a href="https://www.mdpi.com/1420-3049/16/6/4567">lacking</a>. Most of the <a href="https://www.mdpi.com/1420-3049/16/6/4567">existing studies</a> have been conducted in <a href="https://onlinelibrary.wiley.com/doi/full/10.1002/jcp.27360">lab settings</a> using cells or in <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4608712/">animals</a>. So it’s unclear how much curcumin is needed to see anti-inflammatory benefits or how well <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5664031/">we absorb it</a>.</p> <p>Overall, adding turmeric to your food may provide your body with some health benefits, but don’t rely on it to prevent or treat disease on its own.</p> <h2>Safe eating</h2> <p>Inflammation is a major factor in the link between diet and many health conditions.</p> <p>Eating an anti-inflammatory diet is considered safe, likely to support health and to prevent future chronic conditions. If you are looking for tailored dietary advice or an anti-inflammatory meal plan, it’s best to speak with an <a href="https://member.dietitiansaustralia.org.au/Portal/Portal/Search-Directories/Find-a-Dietitian.aspx">accredited practising dietitian</a>.<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/210468/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/lauren-ball-14718">Lauren Ball</a>, Professor of Community Health and Wellbeing, <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, Researcher &amp; Lecturer, <a href="https://theconversation.com/institutions/southern-cross-university-1160">Southern Cross 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.

Does artificial sweetener aspartame really cause cancer? What the WHO listing means for your diet soft drink habit

<p><em><a href="https://theconversation.com/profiles/evangeline-mantzioris-153250">Evangeline Mantzioris</a>, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a></em></p> <p>The International Agency for Research on Cancer (IARC), which is the specialised cancer agency of the World Health Organization, has declared aspartame may be a <a href="https://www.who.int/news/item/14-07-2023-aspartame-hazard-and-risk-assessment-results-released">possible carcinogenic hazard to humans</a>.</p> <p>Another branch of the WHO, the Joint WHO and Food and Agriculture Organization’s Expert Committee on Food Additives has assessed the risk and developed recommendations on how much aspartame is safe to consume. They have recommended the acceptable daily intake be 0 to 40mg per kilo of body weight, as we currently have <a href="https://www.foodstandards.gov.au/consumer/additives/aspartame/Pages/default.aspx">in Australia</a>.</p> <p>A hazard is different to a risk. The hazard rating means it’s an agent that is capable of causing cancer; a risk measures the likelihood it could cause cancer.</p> <p>So what does this hazard assessment mean for you?</p> <h2>Firstly, what is aspartame?</h2> <p><a href="https://www.foodstandards.gov.au/consumer/additives/aspartame/Pages/default.aspx">Aspartame is an artificial sweetener</a> that is 200 times sweeter than sugar, but without any kilojoules.</p> <p>It’s used in a <a href="https://www.foodstandards.gov.au/consumer/additives/aspartame/Pages/default.aspx">variety of products</a> including carbonated drinks such as Coke Zero, Diet Coke, Pepsi Max and some home brand offerings. You can identify aspartame in drinks and foods by looking for additive number 951.</p> <p>Food products such as yogurt and confectionery may also contain aspartame, but it’s not stable at warm temperatures and thus not used in baked goods.</p> <p>Commercial names of aspartame include Equal, Nutrasweet, Canderel and Sugar Twin. In Australia the acceptable daily intake is 40mg per kilo of body weight per day, which is about 60 sachets.</p> <p><a href="https://www.fda.gov/food/food-additives-petitions/aspartame-and-other-sweeteners-food#:%7E:text=How%20many%20packets%20can%20a,based%20on%20its%20sweetness%20intensity%3F&amp;text=Notes%20About%20the%20Chart%3A,50%20mg%2Fkg%20bw%2Fd">In America</a> the acceptable daily intake has been set at 75 sachets.</p> <h2>What evidence have they used to come to this conclusion?</h2> <p><a href="https://www.who.int/news/item/14-07-2023-aspartame-hazard-and-risk-assessment-results-released">IARC looked closely</a> at the <a href="https://cdn.who.int/media/docs/default-source/nutrition-and-food-safety/july-13-final-summary-of-findings-aspartame.pdf?sfvrsn=a531e2c1_5&amp;download=true">evidence base</a> from around the world – using data from observational studies, experimental studies and animal studies.</p> <p>They found there was some limited evidence in human studies linking aspartame and cancer (specifically liver cancer) and limited evidence from animal studies as well.</p> <p>They also considered the biological mechanism studies which showed how cancer may develop from the consumption of aspartame. Usually these are lab-based studies which show exactly how exposure to the agent may lead to a cancer. In this case they found there was limited evidence for how aspartame might cause cancer.</p> <p>There were only three human studies that looked at cancer and aspartame intake. These large observational studies used the intake of soft drinks as an indicator of aspartame intake.</p> <p>All three found a positive association between artificially sweetened beverages and liver cancer in either all of the population they were studying or sub-groups within them. But these studies could not rule out other factors that may have been responsible for the findings.</p> <p>A study <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6284800/">conducted in Europe</a> followed 475,000 people for 11 years and found that each additional serve of diet soft drink consumed per week was linked to a 6% increased risk of liver cancer. However the scientists did conclude that due to the rarity of liver cancer they still had small numbers of people in the study.</p> <p><a href="https://pubmed.ncbi.nlm.nih.gov/35728406/">In a study from the US</a>, increased risk of liver cancer was seen in people with diabetes who drank more than two or more cans of a diet soda a week.</p> <p>The <a href="https://aacrjournals.org/cebp/article/31/10/1907/709398/Sugar-and-Artificially-Sweetened-Beverages-and">third study</a>, also from the US, found an increase in liver cancer risk in men who never smoked and drank two or more artificially sweetened drinks a day.</p> <p>From this they have decided to declare aspartame as a Group 2b “possible carcinogen”. But they have also said more and better research is needed to further understand the relationship between aspartame and cancer.</p> <p>IARC has four categories (groupings) available for potential substances (or as they are referred to by IARC, “agents”) that may cause cancer.</p> <h2>What does each grouping mean?</h2> <p><strong>Group 1 Carcinogenic to humans:</strong> an agent in this group is carcinogenic, which means there is convincing evidence from human studies and we know precisely <em>how</em> it causes cancer. There are 126 agents in this group, including tobacco smoking, alcohol, processed meat, radiation and ionising radiation.</p> <p><strong>Group 2a Probably carcinogenic to humans:</strong> there are positive associations between the agent and cancer in humans, but there may still be other explanations for the association which were not fully examined in the studies. There are 95 agents in this group, including red meat, DDT insecticide and night shift work.</p> <p><strong>Group 2b Possibly carcinogenic in humans:</strong> this means limited evidence of causing cancer in humans, but sufficient evidence from animal studies, or the mechanism of how the agent may be carcinogenic is well understood. This basically means the current evidence indicates an agent may possibly be carcinogenic, but more scientific evidence from better conducted studies is needed. There are now <a href="https://monographs.iarc.who.int/agents-classified-by-the-iarc/">323</a> agents in this group, including aloe vera (whole leaf extract), ginkgo biloba and lead.</p> <p><strong>Group 3 Not classifiable as a carcinogen:</strong> there’s not enough evidence from humans or animals, and there is limited mechanistic evidence of how it may be a carcinogen. There are 500 agents in this group.</p> <h2>So do I have to give up my diet soft drink habit?</h2> <p>For a 70kg person you would need to consume about 14 cans (over 5 litres) of soft drink sweetened with aspartame a day to reach the acceptable daily intake.</p> <p>But we need to remember there may also be aspartame added in other foods consumed. So this is an unrealistic amount to consume, but not impossible.</p> <p>We also need to consider all the evidence on aspartame together. The foods we typically see aspartame in are processed or ultra-processed, which have recently also been <a href="https://theconversation.com/ultra-processed-foods-are-trashing-our-health-and-the-planet-180115">shown to be detrimental to health</a>.</p> <p>And artificial sweeteners (including aspartame) <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2892765/#!po=59.3750">can make people crave more sugar</a>, making them want to eat more food, potentially causing them to gain more weight.</p> <p>All together, this indicates we should be more careful about the amount of artificial sweeteners we consume, since they <a href="https://theconversation.com/the-who-says-we-shouldnt-bother-with-artificial-sweeteners-for-weight-loss-or-health-is-sugar-better-205827">do not provide any health benefits</a>, and have possible adverse effects.</p> <p>But overall, from this evidence, drinking the occasional or even daily can of a diet drink is safe and probably not a cancer risk.</p> <hr /> <p><em>Correction: this article originally stated each serve of soft drink in a study was linked to a 6% increased risk of liver cancer, however it was each additional serve per week.

Weight loss: why you don’t just lose fat when you’re on a diet

<p><em><a href="https://theconversation.com/profiles/adam-collins-1179004">Adam Collins</a>, <a href="https://theconversation.com/institutions/university-of-surrey-1201">University of Surrey</a></em></p> <p>When you go on a diet, you don’t just lose fat – you lose muscle too. This can have many repercussions – not only on your fitness and strength, but on your metabolism.</p> <p>To lose weight (body fat), you need to be in a calorie deficit. This means consuming fewer calories than your body uses, or exercising to burn more calories than you consume.</p> <p>During the first few days in a calorie deficit, the body uses up its small reservoir of <a href="https://pubmed.ncbi.nlm.nih.gov/1615908/">glycogen stores</a> for energy. Glycogen is a string of glucose (sugar) that comes from the carbohydrates you eat. Since carbs are the body’s main energy source, this is why any glucose the body doesn’t immediately use is stored to use for energy later.</p> <p>But as carbohydrate molecules bind with water, this means that when the body stores glycogen, it also stores water in the muscles. As these glycogen stores are used up, the body also releases a significant amount of water. This is often called “water weight”, and explains why some may feel they lose considerable weight early in their diet.</p> <p>Given you only have days’ worth of glycogen stores, this is why the body uses fat to store extra calories for when you need it. Once the glycogen stores are used up, the body shifts to metabolising fat to get the energy it needs to function.</p> <p>But not all tissues can use fat for energy – such as the brain. This is why the body needs to metabolise your muscles when you’re in a calorie deficit.</p> <p>Protein (from the food you eat) is stored in your muscles. The body can convert this stored protein into glucose for energy. But this means you subsequently lose the muscle tissue itself when that happens. This has significant consequences – including <a href="https://pubmed.ncbi.nlm.nih.gov/35103583/">slowing the metabolism</a>, which may ultimately drive weight regain after losing weight.</p> <h2>Muscle loss</h2> <p>Many factors can affect how much muscle you lose while in a calorie deficit.</p> <p>While it was once thought that the more fat you had, the <a href="https://pubmed.ncbi.nlm.nih.gov/10673906/">less muscle you lost</a> in a calorie deficit, this has since been disproved – with both <a href="https://pubmed.ncbi.nlm.nih.gov/3066619/">lean</a> and <a href="https://pubmed.ncbi.nlm.nih.gov/17367567/">obese people</a> losing significant rates of muscle when dieting.</p> <p><a href="https://pubmed.ncbi.nlm.nih.gov/29957829/">Ethnicity</a> and <a href="https://pubmed.ncbi.nlm.nih.gov/32734691/">genetics</a> may, however, play a role – with studies showing black people tend to lose more muscle mass in a calorie deficit than white people do. Some research also suggests that genetic variants may make some people more susceptible to <a href="https://pubmed.ncbi.nlm.nih.gov/32734691/">certain dietary changes</a>, which may determine how much muscle mass they end up losing.</p> <p>Muscle loss will also happen regardless of whether you lose weight <a href="https://pubmed.ncbi.nlm.nih.gov/30925026/">gradually or quickly</a>. A better determinant of how much muscle you’ll lose depends on <a href="https://pubmed.ncbi.nlm.nih.gov/30925026/">how much weight you end up losing</a>. If a person loses 10% of their body weight, typically around 20% of this is fat-free mass (the proportion of body mass that isn’t fat – such as muscle). This can equate to several kilograms of muscle.</p> <p>Many people also think that what you eat while losing weight may determine how much muscle you lose, with it commonly believed that if you eat plenty of protein you’re less likely to lose muscle mass. This is <a href="https://pubmed.ncbi.nlm.nih.gov/19246357/">debatable</a>, with research showing people lose as much muscle on high-protein weight loss diets as people who followed other types of diets.</p> <p>Low-carb diets have also been claimed to promote more fat loss. But studies comparing <a href="https://pubmed.ncbi.nlm.nih.gov/22258266/">different types of diets</a> have found that low-fat high-carb diets seem to offer <a href="https://pubmed.ncbi.nlm.nih.gov/28193517/">the same, if not better, fat loss</a> than low-carb, high-fat diets – with no differences in muscle loss.</p> <h2>Protein and exercise</h2> <p>Given all that has been said, the only way to prevent muscle loss somewhat while losing weight is to combine exercise (particularly <a href="https://pubmed.ncbi.nlm.nih.gov/18356845/">resistance exercise</a> and <a href="https://pubmed.ncbi.nlm.nih.gov/28507015/">endurance exercise</a>) with a diet higher in protein. This is because exercise stimulates muscle growth – but this process can only happen if you have an adequate supply of protein.</p> <p>It’s suggested adults normally aim to consume <a href="https://pubmed.ncbi.nlm.nih.gov/34371981/">0.8g of protein per kilogram of body weight</a> per day to maintain muscle mass. But given the extra demand exercise places on the muscles, a person will probably need to consume 1.2-1.5g of protein per kilogram of body weight to preserve muscle during weight loss. People who exercise a lot may need to increase that to more than <a href="https://pubmed.ncbi.nlm.nih.gov/28642676/">2g per kilogram of body weight</a> when losing weight. <a href="https://pubmed.ncbi.nlm.nih.gov/22221216/">Older people</a> may also need to consume more protein than average.</p> <p>Just be wary of consuming too much protein (more than 2.5g per kilogram of body weight) as eating more than your body uses could have an <a href="https://pubmed.ncbi.nlm.nih.gov/28507015/">adverse effect</a> on your metabolism by potentially making the body less able to draw upon glucose for energy.

Tips for eating a healthy diet on a tight budget

<p>When you’re on a tight budget, the idea of coming up with tasty, healthy meals on a regular basis can sometimes seem beyond us! We easily fall prey to slick grocery marketing, and when it comes to fitting meal preparation into our day, it’s easy to fall into a rut, succumbing to quick fix fast foods again and again.</p> <p>The good news is, you can be thrifty and healthy – with a little organisation and creativity, you can enjoy first class meals on a smart saver’s budget.</p> <p>Here’s a selection of tips to help with your creative cuisine challenge:</p> <ul> <li>A golden rule is don’t shop when you’re hungry, as you’re more likely to buy things you don’t need. Shop with a list rather than buying on the spur of the moment.</li> <li>Buy fresh fruit and vegetables that are in season, and only enough for a week or so, as they go off quickly.</li> <li>Buy generic, no name and home brands where possible, especially for items where you’re not fussed about having the absolute best quality.</li> <li>Add some canned kidney beans, chick peas, lentils or other legumes to mince dishes or stews to make the meal go further. Canned beans are cheap, handy and healthy – a great addition to salads and other meals.</li> <li>Buying in bulk is almost always cheaper. It’s a great idea to buy non-perishable items in bulk (canned foods, dried beans and grains etc.), and you can freeze perishable items such as meat and bread in smaller portions to use as needed.</li> <li>When cooking a big meal, make extra to freeze or use later in the week for lunches or quick suppers. Double recipes, then freeze half.</li> <li>Use less expensive cuts of meat for casseroles that you slow cook; add extra vegetables and beans to make the meal go further.</li> <li>Look at purchasing perishables like meat and sushi at the end of the day when there are often clearances of stock close to use by dates.</li> <li>Check supermarket catalogues for specials and identify any products that you need before you go shopping.</li> <li>Buy block cheese and grate it yourself.</li> <li>Preserve when it’s cheap. Depending on your storage capacity, bottling, drying and freezing fresh fruits and vegetables is an excellent way to cash in on seasonal foods that are lower in cost but higher in taste and nutrition.</li> <li>Brown rice is a great addition to leftover meat and veggies. Although brown rice is slightly more costly than white, the nutritional payoff is well worth it.</li> <li>Pasta, likewise, is quick and easy to prepare, and can be paired with veggies, meat or a fresh salad. Have fun adding your own dash of inspiration (mushrooms, spices and herbs.) Choose wholemeal pasta when you can.</li> <li>Always keep spices, herbs and sauces handy – they can brighten up simple dishes.</li> <li>Bake your own goodies – that way you can make sure everything that goes into them is more nutritious. Plus, they are generally cheaper and tastier than store bought varieties.</li> <li>Soups can’t be beaten for nutrition and convenience, especially since you can use inexpensive soup mixes as your base. At the end of the week, make soup out of all your leftover veggies instead of throwing them out, and freeze anything you won’t eat in a few days. You can find great ideas on the internet by searching for recipes containing whatever you have in the fridge. Again, be creative, adding your own herbs and spices.</li> </ul> <p><em>Image credits: Getty Images</em></p>

Mediterranean diet associated with big reduction in the risk of heart disease and dementia

<p><span style="font-family: -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, Oxygen, Ubuntu, Cantarell, 'Open Sans', 'Helvetica Neue', sans-serif;">Further scientific evidence of the benefits of a “Mediterranean diet” on health have been published this week, extolling the virtues of fruit, veggies, nuts and even a little wine.</span></p> <div class="copy"> <p>In one Australian-led <a href="https://doi.org/10.1136/%20heartjnl-2022-321930" target="_blank" rel="noreferrer noopener">review</a> researchers found women who closely followed a Mediterranean diet were associated with up to 24% lower risk of cardiovascular disease and up to 23% lower risk of death from any cause.</p> <p>This is the first study to examine the association between the Mediterranean diet, cardiovascular disease, and mortality in women specifically, and is published in the journal <em>Heart.</em></p> <p>A <a href="https://bmcmedicine.biomedcentral.com/articles/10.1186/s12916-023-02772-3" target="_blank" rel="noreferrer noopener">UK study</a> in <em>BMC Medicine</em> has also found that men and women with a strict Mediterranean diet had up to 23% lower risk for developing dementia in comparison with those with the lowest level of adherence to the diet.</p> <p>The Mediterranean diet is rich in fruits, vegetables, legumes, nuts, seeds, wholegrains, and olive oil; moderate in fish and shellfish; low to moderate in wine; and low in red meat and processed meats, dairy products, animal fat, and processed foods.</p> <p>Cardiovascular disease is an umbrella term that includes heart, stroke, and blood vessel diseases, and was the <a href="https://www.aihw.gov.au/reports/heart-stroke-vascular-diseases/hsvd-facts/contents/about" target="_blank" rel="noreferrer noopener">underlying cause</a> of one in four deaths in Australia in 2019.</p> <p>“The Mediterranean diet is known for its health benefits, especially for heart health, but most studies and research into diet and heart disease are done primarily in men,” says Anushriya Pant, University of Sydney PhD candidate at the Westmead Applied Research Centre (WARC) and first author of the <em>Heart</em> paper.</p> <p>The study analysed pooled data from 16 studies published between 2006 and 2021, involving over 722,000 female participants aged 18 and above who followed the Mediterranean diet and whose cardiovascular health was monitored for an average of 12.5 years.</p> <p>The researchers found that the reduced risk of cardiovascular disease and death applied to women of all ethnicities..</p> <p>“Now we have confirmed that similar benefits apply for women’s dietary guidelines, and this reflects the strength of the Mediterranean diet for good heart health,” adds Pant.</p> <p>“In medical research, there are sex disparities in how clinical trials are designed. This creates large gaps in clinical data, which can potentially impact the development of health advice. Our work is a step towards addressing this gap.”</p> <p>The researchers acknowledge some limitations to their findings. All studies analysed were observational – so could only establish an association, not causation, between the Mediterranean diet and lowered risk of cardiovascular disease and death – and relied on self-reported food frequency questionnaires. Adjustments for potentially influencing factors also varied across the studies.</p> <p>The second study into dementia is equally supportive of the diet guidelines.</p> <p>UK scientists analysed data from 60,298 individuals from the <a href="https://www.ukbiobank.ac.uk/" target="_blank" rel="noreferrer noopener">UK Biobank</a> – a large-scale biomedical database containing genetic and health information from half a million UK participants – who completed a dietary assessment.</p> <p>Participants were followed for nine years, during which there were 882 cases of dementia.</p> <p>The researchers scored individuals based on how closely their diet matched the key features of a Mediterranean one, while taking into account their genetic risk for dementia.</p> <p>The authors say the findings indicate that, even for those with a higher genetic risk for dementia, having a better diet could reduce the likelihood of developing the condition.</p> <p>“Dementia impacts the lives of millions of individuals throughout the world, and there are currently limited options for treating this condition,” says Dr Oliver Shannon, a lecturer in Human Nutrition and Ageing at Newcastle University, and first author of the study.</p> <p> “Finding ways to reduce our risk of developing dementia is, therefore, a major priority for researchers and clinicians.</p> <p> “Our study suggests that eating a more Mediterranean-like diet could be one strategy to help individuals lower their risk of dementia.”</p> <p>The authors caution that there are limitations to this study, including that their analysis is limited to individuals who self-reported their ethnic background as white, British, or Irish, as only genetic data based on European ancestry was available.</p> <p>Further research is needed in a range of populations to determine the potential benefit for all people.</p> <p>In 2022, it was estimated that there were 401,300 <a href="https://www.aihw.gov.au/reports/dementia/dementia-in-aus/contents/summary" target="_blank" rel="noreferrer noopener">Australians living with dementia</a>.

Warning against latest egg-stremely restrictive diet trend

<p>A viral “egg diet” is the latest weight loss trend taking over TikTok as people continue to find ways to drop a few kilos.</p> <p>The #eggdiet has attracted over 68.5 million views, with a lot of people sharing their weight-loss success. Nutritionists warn the egg-stremely restrictive diet is simply unsustainable and just another eggs-ample of why most diets fail.</p> <p>According to TikTok users, the egg diet consists of eating only eggs for every meal, alongside low-carb snacks such as fruit, veggies, and some additional protein.</p> <p>While this diet is capable of boosting your metabolism and burning fat in the short term, it can then slow the metabolism and make it more difficult to lose weight in the future.</p> <p>One TikTok user trying the diet admitted she had broken it, writing, ”I think the last nine days of eating the bare minimum has caught up with me today. The whole day I just felt nauseous.”</p> <p>A diet focused on one food eggs-cludes many healthy food groups that are otherwise beneficial for your body. This can lead to nutritional deficiencies, an unhealthy amount of weight loss, mood changes, muscle weakness, and hair loss.</p> <p>A nutrition eggs-pert from Fitness Volt says most people fail to stick with their diet long enough for it to work sustainably. They make fast progress, but egg-ventually, they fall off the wagon and return to their previous diet plan.</p> <p>"That's why so many of us lose weight only to regain it shortly afterwards, and it seems long-term, sustainable weight loss is rare nowadays," Saini said.</p> <p>"Fortunately, healthy eating doesn't have to be complicated or unpleasant, and weight management doesn't have to take over your life.</p> <p>"You don't even have to give up your favourite foods. However, you will need to quit looking for short-term fixes and adopt healthier long-term habits.”</p> <p>It is clear the #eggdiet is not sustainable and the lack of nutrition is likely to leave your brain scrambled.</p> <p>The idea is a bit of a crack-up, but don’t <em>whisk</em> it.</p> <p><em>Image credit: TikTok</em></p>

5 diet secrets from around the world

<p>We’ve all heard about the studies showing that certain parts of the world have much longer life expectancies than the rest of us.</p> <p>Often researchers will pinpoint certain aspects of their diet and lifestyles and find that there are specific things that these people are doing to help prolong their life.</p> <p>To save you time, we’ve pulled together a list of the best parts of the diets of each of these countries that you can choose to add to your own diet.</p> <p>The best part is that in a recent study of 35 countries from the Imperial College London, all of them were predicted to increase their life expectancy in the near future. Published in The Lancet journal, the study found that Aussie men born in the year 2030 should live to 84, while females can expect to hit 87.6</p> <p>So, what have you got to lose?</p> <p><strong>1. Green tea</strong></p> <p>Want to reduce your risk of cancer? Add a cup of green tea to your day. The Japanese drink it as a matter of course, and the antioxidants found in green tea have been found to decrease the incidence of some cancers.</p> <p><strong>2. Seafood</strong></p> <p>For many of the countries with longer than average life expectancies, seafood played a big role in their diet. You’ve probably heard of the Mediterranean diet being one of the best on the planet. Access to fresh fish in countries like Monaco means that it is cost effective, and consumed by young and old.</p> <p><strong>3. Yoghurt</strong></p> <p>Help your digestion and metabolism by adding full fat yoghurt to your day like the Swiss do. The protein fills you up so that you don’t overeat, and the calcium has benefits too. But the real boost comes from the probiotics, which can act as a regulator for your digestive system. Keep your gut healthy and you’ll experience less bloating, gas, constipation and diarrhea.</p> <p><strong>4. Fermented foods</strong></p> <p>In South Korea, it’s common to serve kimchi with meals. This is a fermented mix of vegetables that contains probiotics and antioxidants. When paired with their traditional dishes of rice, vegetables, egg and meat, kimchi not only tastes good, it also keeps your gut healthy.</p> <p><strong>5. Miso soup</strong></p> <p>Visit any Japanese restaurant and you’ll most likely find a steaming bowl of miso on your table whether you ordered it or not. It’s such an everyday part of the Japanese diet – and they are expected to live to 80 (for men) and 87 (for women). Miso soup contains miso paste and seaweed, which is packed with calcium and iodine.</p> <p><em>Image credits: Getty Images</em></p>

<p dir="ltr">The foods we eat could help us to prevent the onset of dementia, according to a recent study. </p> <p dir="ltr">The new research shows that people with high levels of three key antioxidants in their blood are less likely to be diagnosed with the devastating disorder. </p> <p dir="ltr">Two of the compounds — lutein and zeaxanthin — are abundant in leafy green vegetables, such as kale and peas. </p> <p dir="ltr">The last antioxidant, beta-cryptoxanthin, is found in abundance in oranges and papayas. </p> <p dir="ltr">Lead researcher Dr May Beydoun, an expert in ageing from the US National Institutes of Health, said, “Extending people's cognitive function is an important public health challenge.”</p> <p dir="ltr">“Antioxidants may help protect the brain from oxidative stress, which can cause cell damage.”</p> <p dir="ltr">Scientists have long advocated that a healthy, balanced diet can help to ward off dementia by boosting heart and circulatory health – both of which are known to play a role in the disease.</p> <p dir="ltr">As well as through diet, people can bolster their blood levels of the three compounds by taking supplements. </p> <p dir="ltr">During the extensive study, the effect of antioxidants on dementia was reduced when other factors were taken into account, including education, income and physical activity.</p> <p dir="ltr">“It's possible that those factors may help explain the relationship between antioxidant levels and dementia,” Dr Beydoun added.</p> <p dir="ltr"><em>Image credits: Getty Images</em></p>
