Soy ProteinDESCRIPTIONThe soybean has long been valued in Asia as a high-protein food rich in nutrients. Due to its apparent ability to reduce cholesterol levels, soy protein products are allowed to carry the FDA approved "heart healthy" label. Soy protein also contains isoflavonones, which may reduce the risk of breast and uterine cancer as well as prevent Osteoporosis. SUGGESTED INTAKES25 g of soy protein per day to reduce cholesterol. This is the equivalent of about 2½ cups of soymilk or ½ pound of tofu. SUPPLEMENTAL USESCholesterol: Cancer: Menopausal symptoms: SAFETYSoy protein is believed to be quite safe. However, isoflavonones may be harmful in certain situations. For instance, isoflavonones may not be safe for women who have already had breast cancer. INTERACTIONS AND CONTRA-INDICATIONSIsoflavonones may interact with hormonal medications such as estrogen, tamoxifen, or raloxifene. In addition, they may interfere with the absorption of Zinc, Iron, and Calcium supplements (5,6,7). Food sources of soy protein include tofu, plain soybeans, soy cheese, soy burgers, soymilk, and tempeh. Soy protein supplements are also available. REFERENCES1. Anderson JW, et al.
