One of the healthiest changes you can make to your diet is to incorporate whole soy foods on a regular basis.
Soy is rich in protein, iron and compounds called isoflavones, which seem to protect against hormone-driven cancers such as prostate cancer in men and breast cancer in women. Soy also helps protect your heart, and new research indicates it may help protect against lung cancer as well.
I recommend one to two daily servings of soy in relatively whole and unrefined forms such as a cup of soymilk, a half cup of tofu, tempeh or green soybeans (edamame) or roasted soy nuts. You can also easily swap meat for tofu in dishes - baked tofu works well as a meat replacement in fajitas, stir fries and casseroles.
