As it turns out, most of the things you probably believe about your favorite foods are about as scientifically accurate as Timecop. To wit ... (click for full)
  1. Myth: Turkey Makes You Sleepy (As Does Warm Milk)

    It's true that turkey has tryptophan (an amino acid that eventually becomes serotonin and melatonin, neurochemicals which do play a role in getting your brain to fall asleep). However, turkey doesn't contain enough tryptophan to have any noticeable effect on your state of consciousness. In fact, it has exactly as much tryptophan as plenty of other dairy, nut, and meat products do (cheddar cheese has more).
  2. Myth: Fresh Produce Is Better Than Canned/Frozen
    556474 v1
    When it comes to nutrition, frozen produce will probably always be better than fresh. It's flash frozen right after it's picked, so it loses fewer nutrients between being harvested and landing on your plate. The same goes for some canned foods. For instance, canned tomatoes are higher in the cancer-fighting antioxidant lycopene than their naked brethren, due to how they're preserved.
  3. Myth: Brown Eggs Are Better For You
    556430 v1
    Ultimately, there's no difference in the eggs based on whether their shells are white or brown. The color is based on the breed of the chicken that laid it. The Rhode Island Red lays brown eggs, and the uber-common Single-Comb White Leghorn lays white eggs. Much like the marshmallows in a box of Lucky Charms, the difference is purely cosmetic -- brown and white eggs taste identical, and there's no difference in nutritional value.
  4. Myth: There Is Such A Thing As "Calorie-Burning" Foods
    556436 v1
    Foods that are called "negative calorie" tend to be some sort of fruit or vegetable. And when it comes to subsisting solely on these foods, one should remember that they don't have all the nutrients you need to continue existing. Most of the weight loss you experience eating these foods is water weight, which returns the instant you start eating like a human again. The deal is the same for the cabbage soup diet, the grapefruit diet, and the Master Cleanse (which causes muscle loss).
  5. Myth: Food Cravings Are Triggered By Nutrients Missing From Your Diet
    556432 v1
    Most Westerners' everyday diet covers the broad majority of their nutritional needs. The amount of calories and the effects of processed food may be a problem, but for the most part, you should be pretty much covered, nutrient-wise. If a lack of nutrients were at the root of food cravings, we'd all be salivating over rainbow chard for its Vitamin A and getting into fistfights over beets and their sweet, sweet folate.
  6. Myth: Different Types Of Alcohol Make You Different Types Of Drunk
    556428 v1
    There's nothing more to your liquor buzz than the amount of ethanol alcohol in it. Because when it comes down to alcohol, different boozes can't give you different buzzes. "The effects of alcohol are similar, whichever form they come in," says Dr. Guy Ratcliffe, the former head of the UK's Medical Council on Alcohol. "Any difference is dependent on the rate at which it is drunk and the amount."
