The Anti-Cancer Diet

Serving = 1 cup soy milk, 4 ounces tofu, or 1/2 cup shelled edamame

Soy may lower the risk for breast and prostate cancers. You'll get more benefit from whole soy (edamame, tofu and soy milk) than from foods with processed soy protein (energy bars), says Alice Bender, R.D., a dietician with the American Institute for Cancer Research. One caution: Some women with breast cancer should avoid soy—talk with your doctor.
