Soy milk can increase the danger of breast most cancers. Fat-free meals are more healthy than high-fat meals. Vegans and vegetarians are poor in protein. Some false concepts about vitamin appear to linger in American tradition like a horrible music caught in your head.
So, to set the document straight, we requested 10 of the highest vitamin consultants within the United States a easy query: What is one vitamin delusion you would like would go away – and why? Here’s what they mentioned.
Myth No 1: Fresh fruit and veggies are all the time more healthy than canned, frozen or dried varieties.
Despite the enduring perception that “contemporary is greatest,” analysis has discovered that frozen, canned and dried fruit and veggies will be simply as nutritious as their contemporary counterparts.
“They can be a cash saver and a simple means to ensure there are all the time fruit and veggies out there at residence,” mentioned Sara Bleich, outgoing director of vitamin safety and well being fairness on the US Department of Agriculture and a professor of public well being coverage on the Harvard T.H. Chan School of Public Health. One caveat: Some canned, frozen and dried varieties include sneaky substances akin to added sugars, saturated fat and sodium, Bleich mentioned, so be sure you learn vitamin labels and go for merchandise that maintain these substances to a minimal.
Myth No 2: All fats is dangerous.
When research revealed within the late Nineteen Forties discovered correlations between high-fat diets and excessive ranges of ldl cholesterol, consultants reasoned that if you happen to lowered the quantity of complete fat in your food regimen, your threat for coronary heart illness would go down. By the Nineteen Eighties, docs, federal well being consultants, the meals business and the information media had been reporting {that a} low-fat food regimen may benefit everybody, though there was no stable proof that doing so would stop points akin to coronary heart illness or chubby and weight problems.
Dr Vijaya Surampudi, an assistant professor of drugs on the UCLA Center for Human Nutrition, mentioned that in consequence, the vilification of fat led many individuals – and meals producers – to switch energy from fats with energy from refined carbohydrates akin to white flour and added sugar. (Remember SnackWell’s?) “Instead of serving to the nation keep slim, the charges of chubby and weight problems went up considerably,” she mentioned.
In actuality, Surampudi added, not all fat are dangerous. Although sure kinds of fat, together with saturated and trans fat, can enhance your threat for situations akin to coronary heart illness and stroke, wholesome fat – akin to monounsaturated fat (present in olive and different plant oils, avocados, and sure nuts and seeds) and polyunsaturated fat (present in sunflower and different plant oils, walnuts, fish and flaxseeds) – truly assist cut back your threat. Good fat are additionally essential for supplying vitality, producing essential hormones, supporting cell operate and aiding within the absorption of some vitamins.
If you see a product labeled “fat-free,” don’t mechanically assume it’s wholesome, Surampudi mentioned. Instead, prioritize merchandise with easy substances and no added sugars.
Myth No 3: ‘Calories in, energy out’ is a very powerful issue for long-term weight acquire.
It’s true that if you happen to devour extra energy than you burn, you’ll most likely acquire weight. And if you happen to burn extra energy than you devour, you’ll most likely reduce weight – at the very least for the quick time period.
But the analysis doesn’t recommend that consuming extra will trigger sustained weight acquire that ends in turning into chubby or overweight. “Rather, it’s the kinds of meals we eat which may be the long-term drivers” of these situations, mentioned Dr Dariush Mozaffarian, a professor of vitamin and drugs on the Friedman School of Nutrition Science and Policy at Tufts University. Ultraprocessed meals – akin to refined starchy snacks, cereals, crackers, vitality bars, baked items, sodas and sweets – will be significantly dangerous for weight acquire, as they’re quickly digested and flood the bloodstream with glucose, fructose and amino acids, that are transformed to fats by the liver. Instead, what’s wanted for sustaining a wholesome weight is a shift from counting energy to prioritizing wholesome consuming general – high quality over amount.
Myth No 4: People with Type 2 diabetes shouldn’t eat fruit.
This delusion stems from conflating fruit juices – which might increase blood sugar ranges due to their excessive sugar and low fiber content material – with complete fruits.
But analysis has discovered that this isn’t the case. Some research present, for example, that those that devour one serving of complete fruit per day – significantly blueberries, grapes and apples – have a decrease threat of creating Type 2 diabetes. And different analysis means that if you have already got Type 2 diabetes, consuming complete fruits might help management your blood sugar.

There’s a notion that plant-based milks, akin to these constituted of oats, almonds, rice and hemp, are extra nutritious than cow’s milk. “It’s simply not true,” mentioned Kathleen Merrigan, a professor of sustainable meals methods at Arizona State University and a former US deputy secretary of agriculture. Consider protein: Typically, cow’s milk has about 8 grams of protein per cup, whereas almond milk sometimes has round 1 or 2 grams per cup, and oat milk often has round 2 or 3 grams per cup. While the vitamin of plant-based drinks can differ, Merrigan mentioned, many have extra added substances – akin to sodium and added sugars, which might contribute to poor well being – than cow’s milk.

They are wealthy in vitamin C, potassium, fiber and different vitamins, particularly when consumed with the pores and skin. They are additionally cheap and located year-round in grocery shops, making them extra accessible. Healthier preparation strategies embrace roasting, baking, boiling and air frying.
Myth No 7: You ought to by no means feed peanut merchandise to your kids inside their first few years of life.
For years, consultants instructed new dad and mom that one of the simplest ways to forestall their kids from creating meals allergy symptoms was to keep away from feeding them frequent allergenic meals, akin to peanuts or eggs, throughout their first few years of life. But now, allergy consultants say, it’s higher to introduce peanut merchandise to your baby early on.
If your child doesn’t have extreme eczema or a identified meals allergy, you can begin introducing peanut merchandise (akin to watered-down peanut butter, peanut puffs or peanut powders, however not complete peanuts) at round 4 to six months, when your child is prepared for solids.

If your child has extreme eczema, first ask your pediatrician or an allergist about beginning peanut merchandise at about 4 months. “It can be essential to feed your child a various food regimen of their first yr of life to forestall meals allergy symptoms,” Gupta mentioned.
Myth No 8: The protein in crops is incomplete.
“‘Where do you get your protein?’ is the No 1 query vegetarians get requested,” mentioned Christopher Gardner, a vitamin scientist and professor of drugs at Stanford University. “The delusion is that crops are utterly lacking some amino acids,” often known as the constructing blocks of proteins, he mentioned. But in actuality, all plant-based meals include all 20 amino acids, together with all 9 important amino acids, Gardner mentioned; the distinction is that the proportion of those amino acids isn’t as supreme because the proportion of amino acids in animal-based meals. So, to get an enough combine, you merely must eat a wide range of plant-based meals all through the day – akin to beans, grains and nuts – and eat sufficient complete protein. Luckily, most Americans get greater than sufficient protein every day. “It’s simpler than most individuals suppose,” Gardner mentioned.

High doses of plant estrogens in soy known as isoflavones have been discovered to stimulate breast tumor cell development in animal research. “However, this relationship has not been substantiated in human research,” mentioned Dr Frank Hu, a professor and the chair of the division of vitamin on the Harvard T.H. Chan School of Public Health. So far, the science doesn’t point out a hyperlink between soy consumption and breast-cancer threat in people. Instead, consuming soy-based meals and drinks – akin to tofu, tempeh, edamame, miso and soy milk – could also have a protecting impact towards breast-cancer threat and survival. “Soy meals are additionally a powerhouse of helpful vitamins associated to lowered coronary heart illness threat, akin to high-quality protein, fiber, nutritional vitamins and minerals,” Hu mentioned. The analysis is obvious: Feel assured incorporating soy meals into your food regimen.
Myth No 10: Fundamental vitamin recommendation retains altering – quite a bit.
This shouldn’t be the case, mentioned Dr Marion Nestle, a professor emerita of vitamin, meals research and public well being at New York University. “In the Nineteen Fifties, the primary dietary suggestions for prevention of weight problems, Type 2 diabetes, coronary heart illness and the like suggested balancing energy and minimizing meals excessive in saturated fats, salt and sugar. The present US Dietary Guidelines urge the identical.” Yes, science evolves, however the bottom-line dietary steering stays constant.

Mostly crops.” That recommendation labored 70 years in the past, and it nonetheless does as we speak, Nestle mentioned. And it leaves loads of room for consuming meals you like.
