If tough Navy SEALs eat soybeans, you can, too. Dietitian Wendy Jo Peterson, of Virginia Beach, who's married to a SEAL, serves him and his Navy buddies edamame. "They think they don't like it until I make them try it, and afterward, I tell them it's soybeans." Peterson calls soy a "perfect food." It has the protein of meat, the fiber of a whole grain, and the antioxidants, vitamins, and minerals of the best vegetables and fruits. If you don't like tofu and soy milk-there are easy ways to boost your soy intake. Soy nuts and the soy protein used in some protein shakes and bars not only taste great but are very guy-friendly.
