Nutrition Facts...Or Fictions

I've just put down an article that seems to have some false bone-density information. The writer said that the high fructose corn syrup (HFCS) in soda is linked to  osteoporosis. While HFCS is dangerous because it taxes the pancreas and may raise our risk of developing diabetes type 2, I've never seen any studies suggesting it leaches calcium from our bones. Rather, it's the phosphoric acid in soda that has been shown consistently to give us bone density problems. 

So this got me thinking of other examples of nutrition facts...and fictions. For fun, test your knowledge below. What do you think?

"Eating carrots can improve vision"
False! "Carrots contain a compound linked to fighting cancer but for protecting your eyes, spinach and other dark leafy veggies are better bets," said Wendy Bazilian, a registered dietician and and author of The SuperFoods Rx Diet to me. Why? They're high in lutein and zeaxanthin, two antioxidants that seem to curb degenerative eye diseases, says Johns Hopkins research.

"Coffee helps headaches"
True! "A 200 mg dose of caffeine (that's about the size of 1 mug) actually gives relief a half-hour faster than 400 mg of Advil, says a study in the journal of Current Pain and Headache Reports. Bazilian explained to me that caffeine constricts blood vessels in the brain to lessen the throbbing feeling.

"An apple a day keeps the doctor away"
True! Packed with fiber and phytochemicals, apples do take a bite out of diseases. Quercetin is its secret weapon against cancers found one study from the Mayo Clinic. It also may improve lung function, aid in the brain's cognitive abilities, and lower cholesterol. But perhaps the biggest vote for apples? They seem to keep you thin. A new Brazilian study showed that those who ate 3 apples a day were skinnier than those who didn't!

"Yogurt cures yeast infections"
True! Its live bacteria helps restore the delicate balance of yeast with other bacteria that exist naturally in the ladies' bodies, says Mary Jane Minkin, M.D., a professor of gyno at Yale. She even told me that coating an unused tampon with a spoonful of plain yogurt and then inserting it 3 times a day can be enough to get the good flora going again.

"Milk prevents osteoporosis"
False! I love this one because as a lactose-intolerant one, people have asked me about brittle bones later. Dairy intake has very very very very little to do with maintaining high bone density. Weight bearing exercises and eating veggies is a much better way to stay healthy than milk or a hunk of cheese daily--and without the saturated fat. Calcium in milk is not that easily absorbed by our bones, explains experts like David Grotto, RD and author of 101 Foods That Could Save Your Life.
