The fact about 12 health myths

In a 2002 German revise, researchers found that the burning process produces a novel type of cancer-fighting antioxidant in bread that is eight times more plentiful in the crust than in the crumb. Breads simply labeled "wheat" are frequently made with a combination of enriched white flour and whole-wheat flour and have less fiber.

If You are Go Out With Wet Hair, You'll Catch a Cold:

The truth is: You will suffer cold but will be just fine healthwise, says Jim Sears, a board-certified pediatrician in San Clemente, California, and a cohost of the daytime-TV show The Doctors. Half the group stayed in a temperate room while the rest took a bath and stood dripping wet in a entry for half an hour, then got undressed but wore wet socks for a few more hours. The wet group did not catch any more colds than the dry. Sears's conclusion: "Feeling cold doesn't affect your immune system."

If You Cross Your Eyes, They will Stay That Way:

The truth is: "There's no harm in charitable eye crossing," says W. Walker Motley, an assistant professor of ophthalmology at the University of Cincinnati College of Medicine. But if you notice your child doing this a lot, he might have other vision problems.

You Should supply a Cold and Starve a Fever:

The truth is: In both cases, eat and drink, then drink some more. "Staying hydrated is the most significant thing to do, because you lose a lot of fluids when you're ill," says Sears, who adds that there's no need for special beverages containing electrolytes (like Gatorade) except you are severely dehydrated from vomiting or diarrhea.

chewing gum Stays in Your Stomach for Seven Years:

The truth is: Your Little Leaguer's wad of Big League Chew won't (literally) stick about until high school graduation. "As with most nonfood objects that kids swallow, fluids carry gum through the intestinal tract, and within days it passes," says David Pollack, a older physician in the Children's Hospital of Philadelphia Care Network. And even although gum isn't easily broken down in the digestive system, it probably won't cause a stomachache, either.

An Apple a Day Keeps the Doctor Away:

The truth is: A handful of blueberries a day will keep the doctor away more efficiently. Blueberries are a nutritional jackpot, rich in antioxidants and fiber, and they are also easy to toss into cereal and yogurt. That said, eating a mixture of fruits and vegetables is important to prevent many chronic illnesses, such as heart disease, high blood pressure, and diabetes, down the road.

You Lose 75 Percent of Your Body Heat throughout Your Head:

The truth is: "This proverb was probably based on an infant's head size, which is a much greater percentage of the total body than an adult head," says Pollack. That's why it is important to make sure an infant's head residue covered in cold weather. But for an adult, the figure is additional like 10 percent. And keep in mind that heat escapes from any uncovered area (feet, arms, hands), so putting on a hat is no more important than slipping on gloves.

To Get Rid of Hiccups, Have Someone Startle You:

The truth is: Mainly home remedies, like holding your breath or drinking from a glass of water backward, haven't been medically proven to be effective, says Pollack. However, you can try this trick dating back to 1971, when it was available in The New England Journal of Medicine: Swallow one teaspoon of white granulated sugar. According to the study, this method resulted in the cessation of hiccups in 19 out of 20 afflicted patients. Sweet.

Eating Fish Makes You Smart:

The truth is: For kids up to age three or four, this is certainly the case. Fish, especially oily ones, such as salmon, are filled with omega-3 fatty acids, including DHA (docosahexaenoic acid). "DHA is particularly beneficial in the first two years of life for brain development, cognition, and visual acuity," says Beverly Hills pediatrician Scott W. Cohen, the author of Eat, Sleep, Poop: A Common Sense Guide to Your Baby's First Year ($16, amazon.com). And a 2008 study in Clinical Pediatrics showed an increase in vocabulary and comprehension for four-year-olds who be given daily DHA supplements. Omega-3 options for the fish-phobic? Try avocados, walnuts, and canola oil.

You Shouldn't Swim for an Hour once Eating:
The truth is: Splash away. "After you eat, more blood flows to the digestive system and away from the muscles," says Cohen. "The thinking was that if you exercised persistently right after eating, that lack of blood would cause you to cramp up and drown." But that won't happen. Sears concurs: "You might have less energy to swim energetically, but it shouldn't slow down your ability to tread water or play."

Every Child must Needs a Daily Multivitamin:
The truth is: Children who are only breast-fed during their first year should be given a vitamin D supplement. After that, a multivitamin won't injure anyone, but many experts say that even if your child is in a picky phase, there's no need to sneak Fred, Wilma, and company into his applesauce. "Even mainly fussy eaters grow normally," Cohen says. "Your kids will finally get what they need, even if it seems as if they're subsisting on air and sunlight."

Warm Milk Will Help You go down Asleep:

The truth is: Milk contains small amounts of tryptophan (the same amino acid in turkey), "but you would have to drink gallons to get any soporific result," says Michael Breus, a clinical psychologist in Scottsdale, Arizona, who specializes in sleep disorders. "What is efficient is a routine to help kids wind down," he says. And if a glass of warm milk is part of the process, it can have a placebo effect, in spite of of science.
