6 Double-Duty Beauty Foods (Page 6)


5. Tofu

Beauty benefit: Keeps wrinkles at bay
Tofu—and other soyfoods, such as edamame and soymilk—may help to preserve skin-firming collagen because it is rich in isoflavones. In a study published in the Journal of the American College of Nutrition, mice fed isoflavones and exposed to ultraviolet radiation had fewer wrinkles and smoother skin than mice that were exposed to UV light but didn’t get isoflavones. The researchers believe that isoflavones help prevent collagen breakdown.

Health benefit: Improves cholesterol
Eating 25 grams of soy protein daily (about 1 1/4 cups of tofu or edamame) may help lower your "bad" LDL and total cholesterol levels, suggests a review of 30 studies. One hypothesis is that soy protein lowers cholesterol by helping the liver clear more LDL from the body.
