Food myth: Avoid eggs because of their cholesterol content

 

eggssiambizkit/ShutterstockHealthy eating: Eggs have gotten an unfounded bad rap; the latest research shows that they don’t actually contribute to high cholesterol. (Here's why American refrigerate eggs and Europeans don't.) In fact, eggs are an inexpensive source of many nutrients, including zinc and iron, antioxidants lutein and zeaxanthin, vitamin D, and the brain-boosting chemical choline. Keep cholesterol in check by monitoring saturated fat in your diet.

breadStock Asso/ShutterstockHealthy eating: Choosing the healthiest carbohydrates, especially whole grains, is more important to your well-being. At least seven major studies show that women and men who eat whole grains have 20 to 30 percent less heart disease. Separately, in a 2010 study of more than 13,000 adults, those who ate the most servings of whole grains had lower body weight.

Food myth: Using margarine instead of butter will save calories

 

butterElena moiseeva/ShutterstockHealthy eating: Butter and margarine have about the same amount of calories. But while margarine, made from vegetable oils, was created as a more healthful alternative to butter (which contains cholesterol and saturated fat), some margarines are actually unhealthier because they contain trans fats, which have even more adverse effects on cholesterol and heart health. (This is the real difference between butter and margarine.) If you choose margarine, look for trans fat-free brands.

Food myth: Nuts are as bad as junk food

 

NutsJulia Sudnitskaya/ShutterstockHealthy eating: Nuts are excellent sources of protein and other nutrients, as long as you keep servings to a handful. Harvard researchers found that women who ate that amount about five times a week were 20 percent less likely to develop type 2 diabetes than those who didn’t eat them as often. (These are the five healthiest nuts you can eat.) Additionally, several large studies have found that a regular intake of nuts protects against heart disease.

Food myth: Those with diabetes have to give up sweets

 

cupcakelocrifa/ShutterstockHealthy eating: In moderation, an occasional sweet treat is fine. The key to maintaining healthy blood glucose levels is balancing meals and snacks to provide a mixture of carbs, fats, and proteins.

Food myth: Cranberry juice can cure a urinary tract infection

 

CranberryBrent Hofacker/ShutterstockHealthy eating: There’s no proof that cranberry juice or supplements can treat an infection, which should be medicated with antibiotics. But drinking the juice or taking supplements regularly can prevent such infections in the first place because compounds in the juice stop infection-causing bacteria from sticking to the bladder wall. Here's what to actually do if you've got a UTI.

Food myth: Don’t drink milk when you have a cold

Food myth: Spicy food gives you an ulcer

 

spicy-foodVICUSCHKA/ShutterstockHealthy eating: Spices don’t trigger ulcers. We now know that the bacteria Helicobacter pylori causes almost all ulcers, except those triggered by certain medications, like aspirin. What spices can do is exacerbate an irritable bowel, which people often mistake for an ulcer.

Food myth: Feed a cold, starve a fever

 

soupChristian Fischer/ShutterstockHealthy eating: There’s no medical reason to limit foods when you’re feverish. While you may have less of an appetite, you should eat whatever you can tolerate. (These are 6 clear signs you've got the flu.) In fact, when you’re sick, your nutritional needs increase because your metabolic rate goes up.

Food myth: Fat-free and low-fat foods are always better than full-fat versions

 

cookieNatali Zakharova/ShutterstockHealthy eating: When it comes to meat and some dairy products, it’s generally true that the less fat, the better. But not so with packaged, processed foods. Call it the “Snackwells” lesson: When manufacturers remove a certain ingredient (fat) from a certain food (cookies), they need to compensate for the taste by adding other not-so-healthy ingredients (sugar). Companies are constantly tinkering with the ratios of sugar, fat, salt and other ingredients in such foods. Now, most nutrition experts believe you’re better off avoiding artificially fat-free foods and opting instead for whole foods with healthy fats, like nuts.

Food myth: Frozen and canned fruits and veggies are less nutritious than fresh ones

Healthy eating: Fresh fruits and vegetables are more nutritious than the frozen and canned variety—the instant they are picked. However, the foods you find in the produce section have often had a long journey, often spending days or even weeks in transit from the farm or orchard. During shipping and storage, natural enzymes are released in fresh fruit and vegetables that cause them to lose nutrients. By contrast, food processors quick-freeze fresh-picked produce, which preserves much of its vitamin and mineral content.

Food myth: Eating carrots will improve your eyesight

carrotsTimolina/ShutterstockHealthy eating: This widespread carrot myth has been around since World War II, when rumors circulated that pilots ate lots of the vegetable to keep their vision in top shape. In reality, the fighter's bionic eyesight was the result of improved technology. (Here's what you CAN do to protect your eyesight over time.)  Since then, the myth remains unfounded. Unless you're way deficient in vitamin A, more carrots won't make bad vision any better.

Food myth: Red wine is the only good-for-you alcohol

red-wineAfrica Studio/ShutterstockHealthy eating: It's true, red wine gets a lot of good press. But recent studies have found that ethanol itself—that is, the stuff that makes alcohol—is what raises levels of protective HDL, or good cholesterol, and helps reduce clotting factors that contribute to heart attack and stroke. That means that in moderation, any type of alcoholic beverage will make for a happier heart.
