Taste depends on nature and nurture. Here are 7 ways you can learn to enjoy foods you don’t like

<p><em><a href="https://theconversation.com/profiles/nicholas-archer-181464">Nicholas Archer</a>, <a href="https://theconversation.com/institutions/csiro-1035">CSIRO</a> and <a href="https://theconversation.com/profiles/astrid-poelman-1481227">Astrid Poelman</a>, <a href="https://theconversation.com/institutions/csiro-1035">CSIRO</a></em></p> <p>You’re out for dinner with a bunch of friends, one of whom orders pizza with anchovies and olives to share, but you hate olives and anchovies! Do you pipe up with your preferred choice – Hawaiian – or stay quiet?</p> <p>This scene plays out every day around the world. Some people ferociously defend their personal tastes. But many would rather expand their palate, and not have to rock the boat the next time someone in their friend group orders pizza.</p> <p>Is it possible to train your tastebuds to enjoy foods you previously didn’t, like training a muscle at the gym?</p> <h2>What determines ‘taste’?</h2> <p>Taste is a complex system we evolved to help us navigate the environment. It helps us select foods with nutritional value and reject anything potentially harmful.</p> <p>Foods are made up of different compounds, including nutrients (such as proteins, sugars and fats) and <a href="https://www.youtube.com/watch?v=2P_0HGRWgXw">aromas</a> that are detected by sensors in the mouth and nose. These sensors create the <a href="https://www.youtube.com/watch?v=MZn2PMUWO-Y">flavour of food</a>. While taste is what the tastebuds on your tongue pick up, flavour is the combination of how something smells and tastes. Together with texture, appearance and sound, these senses collectively influence your food preferences.</p> <figure><iframe src="https://www.youtube.com/embed/MZn2PMUWO-Y?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption><span class="caption">Flavour is the overall impression you get when eating.</span></figcaption></figure> <p>Many factors influence food preferences, including age, genetics and environment. We each live in our own sensory world and no two people will have the same <a href="https://theconversation.com/curious-kids-why-do-some-people-find-some-foods-yummy-but-others-find-the-same-foods-yucky-77671">experience while eating</a>.</p> <p>Food preferences also change with age. Research has found young children have a <a href="https://pubmed.ncbi.nlm.nih.gov/24452237/">natural preference</a> for sweet and salty tastes and a dislike of bitter tastes. As they grow older their ability to like bitter foods grows.</p> <p>Emerging evidence shows bacteria in saliva can also produce enzymes that influence the taste of foods. For instance, saliva has been shown to cause the release of sulphur aromas in cauliflower. The <a href="https://www.acs.org/pressroom/presspacs/2021/acs-presspac-september-22-2021/childrens-dislike-of-cauliflower-broccoli-could-be-written-in-their-microbiome.html">more sulphur that is produced</a>, the less likely a kid is to enjoy the taste of cauliflower.</p> <h2>Nature versus nurture</h2> <p>Both genetics and the environment play a crucial role in determining food preferences. Twin studies estimate genetics have a moderate influence on food preferences (between 32% and 54%, depending on the food type) in <a href="https://www.sciencedirect.com/science/article/pii/S000291652305027X?via%3Dihub">children</a>, <a href="https://pubmed.ncbi.nlm.nih.gov/27385609/">adolescents</a> and <a href="https://www.cambridge.org/core/journals/twin-research-and-human-genetics/article/dietary-patterns-and-heritability-of-food-choice-in-a-uk-female-twin-cohort/8507AAF01330C599BAC62BCC0EF4CF06">adults</a>.</p> <p>However, since our cultural environment and the foods we’re exposed to also shape our preferences, these <a href="https://pubmed.ncbi.nlm.nih.gov/24452237/">preferences are learned</a> to a large degree.</p> <p>A lot of this learning takes place during childhood, at home and other places we eat. This isn’t textbook learning. <a href="https://www.cabidigitallibrary.org/doi/10.1079/9780851990323.0093">It’s learning</a> by experiencing (eating), which typically leads to increased liking of the food – or by watching what others do (modelling), which can lead to both positive or negative associations.</p> <p><a href="https://www.sciencedirect.com/science/article/pii/S000291652305027X?via%3Dihub">Research</a> has shown how environmental influences on food preferences change between childhood and adulthood. For children, the main factor is the home environment, which makes sense as kids are more likely to be influenced by foods prepared and eaten at home. Environmental factors influencing adults and adolescents are more varied.</p> <h2>The process of ‘acquiring’ taste</h2> <p>Coffee and beer are good examples of bitter foods people “acquire” a taste for as they grow up. The ability to overcome the dislike of these is largely due to:</p> <ul> <li> <p>the social context in which they’re consumed. For example, in many countries they may be associated with passage into adulthood.</p> </li> <li> <p>the physiological effects of the compounds they contain – caffeine in coffee and alcohol in beer. Many people find these effects desirable.</p> </li> </ul> <p>But what about acquiring a taste for foods that don’t provide such desirable feelings, but which are good for you, such as kale or fatty fish? Is it possible to gain an acceptance for these?</p> <p>Here are some strategies that can help you learn to enjoy foods you currently don’t:</p> <ol> <li> <p>eat, and keep eating. Only a small portion is needed to build a liking for a specific taste over time. It may take 10–15 attempts or more before you can say you “like” the food.</p> </li> <li> <p><a href="https://www.sciencedirect.com/science/article/pii/S0950329302001106">mask bitterness</a> by eating it with other foods or ingredients that contain salt or sugar. For instance, you can pair bitter rocket with a sweet salad dressing.</p> </li> <li> <p>eat it repeatedly in a positive context. That could mean eating it after playing your favourite sport or with people you like. Alternatively, you could eat it with foods you already enjoy; if it’s a specific vegetable, try pairing it with your favourite protein.</p> </li> <li> <p>eat it when you’re hungry. In a hungry state you’ll be more willing to accept a taste you might not appreciate on a full stomach.</p> </li> <li> <p>remind yourself why you want to enjoy this food. You may be changing your diet for health reasons, or because you’ve moved countries and are struggling with the local cuisine. Your reason will help motivate you.</p> </li> <li> <p>start young (if possible). It’s easier for children to learn to like new foods as their tastes are less established.</p> </li> <li> <p>remember: the more foods you like, the easier it’ll become to learn to like others.</p> </li> </ol> <p>A balanced and varied diet is essential for good health. <a href="https://www.sciencedirect.com/science/article/pii/S0195666315003438?ref=pdf_download&amp;fr=RR-2&amp;rr=82a5fd5069821f63">Picky eating</a> can become a problem if it leads to vitamin and mineral deficiencies – especially if you’re avoiding entire food groups, such as vegetables. At the same time, eating too many tasty but energy-dense foods can increase your risk of chronic disease, including obesity.</p> <p>Understanding how your food preferences have formed, and how they can evolve, is a first step to getting on the path of healthier eating.<!-- Below is The Conversation's page counter tag.

Why desexing dogs isn't always the best thing to do

<p>In pet-loving nations such as Australia, nobody likes the idea of dogs churning out litters in squalid conditions or sitting homeless in a shelter.</p> <p>Responsible dog owners are therefore strongly encouraged to desex their pets, through programs such as <a href="https://ndn.org.au/get-involved/2019-national-desexing-month/">national desexing month</a> and <a href="https://dogshome.com/the-homes-campaigns/if-you-love-them-desex-them">low-cost surgery schemes</a>. In some places in Australia, it is even <a href="https://kb.rspca.org.au/knowledge-base/is-desexing-mandatory-for-cats-and-dogs/">compulsory</a>.</p> <p>But as we try to limit unwanted dogs, experts estimate there is demand in Australia for nearly <a href="http://ankc.org.au/media/6598/a-forensic-view-of-puppy-breeding-in-australiav4.pdf">half a million new puppies</a> every year.</p> <p>Many desexed family pets are the ideal parents of the next generation of family companions, having demonstrated their ability to fit in with family life. Yet by desexing as early as possible, we are removing the best source of happy healthy pets from the doggy gene pool.</p> <p>We argue there’s room for responsible pet owners and breeders to work together, breeding ideal companion animals and reducing the number of unwanted or unsafe dogs left in shelters.</p> <p><strong>We want happy, loyal pups</strong></p> <p>People want their dogs to suit their family’s needs: tall or short, short-coated or non-shedding, couch potato or running buddy. We have created hundreds of breeds to meet these preferences. However, Australian pet-owners most value dogs that are <a href="https://www.sciencedirect.com/science/article/pii/S0168159109001555">affectionate, friendly, obedient and safe with children.</a></p> <p>Such dogs are a combination of nature and nurture. Most temperament traits in dogs, including <a href="https://www.researchgate.net/publication/40101976_Genetic_variation_in_aggression-related_traits_in_Golden_Retriever_dogs">aggression</a>, have a genetic basis. Dogs bred for working roles, such as police work, have physical and behavioural assessments to make sure they can do their jobs well.</p> <p>If we treat being a happy and safe companion as a job, we need to <a href="https://www.ingentaconnect.com/content/ufaw/aw/2010/00000019/a00102s1/art00003">select breeding dogs with the right characteristics to succeed</a>. This begins with carefully selecting parents who also have these traits. Many dogs who would breed perfect family pets are themselves family pets, and owners have years of observation to rely on.</p> <p>A puppy’s early life is also extremely important for creating a suitable pet. Raising them in rich environments, with plenty of affection, <a href="https://www.magonlinelibrary.com/doi/full/10.12968/vetn.2013.4.6.334">equips puppies with important life-skills</a>. For those destined for companionship, this experience includes regular playtime with humans and exposure to life in a modern household. These requirements highlight the need to consider where dogs come from.</p> <p><strong>Professionals, hobbyists or irresponsible owners</strong></p> <p>While we don’t have firm data on where Australians get their pets, we can safely assume there are three main sources: commercial breeders, recreational or hobby breeders, and members of the general public who fail to desex their pet dogs.</p> <p>While new <a href="http://agriculture.vic.gov.au/pets/puppy-farm-legislation">legislation</a> in Victoria targets the worst puppy mills, even the best large-scale commercial operations may struggle to give puppies the attention they need early in life.</p> <p>Meanwhile, recreational breeders, who are often strongly motivated to provide the best upbringing possible, may not select their breeding dogs on the basis of their performance as pets.</p> <p>Instead, they may focus on success in the show ring or pedigree bloodlines, potentially producing very expensive dogs ill-equipped to be great pets.</p> <p>And what of the traditional source of the family dog – pet owners who fail to desex their pets? If high rates of desexing exclude from the gene pool those really wonderful pet dogs owned by “responsible” owners, and only irresponsible owners allow their dogs to breed, the resulting puppies are far less likely to possess the traits so desired by prospective homes.</p> <p>One has only to visit a local shelter to see the unfortunate results of accidental matings among the many wonderful dogs seeking a new home. Thousands of dogs are surrendered in <a href="https://www.mdpi.com/2076-2615/7/7/50">Australia shelters every year</a>.</p> <p>To secure future generations of successful companion dogs, <a href="https://www.frontiersin.org/articles/10.3389/fvets.2019.00241/full">a new approach to breeding is needed</a>. Restricting who can breed, and issuing penalties to those who break the rules, is one strategy that must of course be developed and enforced.</p> <p>All breeders must be educated about careful selection of parents, and suitable early experiences in breeding puppies that will excel as pets.</p> <p>But the final piece in the puzzle should be collaboration between responsible breeders and pet owners in the breeding process.<span class="attribution"><a href="http://creativecommons.org/licenses/by-nc/4.0/" class="license"></a></span></p> <p>If more responsible dog owners were encouraged not to desex their dogs at an early age, but to wait until their dogs’ physical and behavioural health has been thoroughly demonstrated, the very best companion dogs could be permitted to contribute their genes to the next generation.</p> <p>This more nuanced approach, where owners and breeders work together to identify dogs of exemplary health and temperament, could enrich the companion dog gene pool and result in happier owners, happier dogs, and emptier shelters. Although not desexing companion dogs does carry risks – from <a href="https://theconversation.com/why-decisions-to-desex-male-dogs-just-got-more-complicated-95520">behavioural issues to unwanted puppies</a> – we believe this is worth considering. Always discuss your concerns with your veterinarian. Not snipping in haste may be a better option than snipping everything.<!-- Below is The Conversation's page counter tag.
