Soy Protein Content of Foods

Soy contains the isoflavones (also called phytoestrogens) genistein and diadzen that are not found in any other foods. These isoflavones have been scientifically proven to reduce blood cholesterol levels and slow down bone loss, thus preventing heart disease and osteoporosis. For some women, isoflavone intake also has reduced symptoms of menopause, specifically hot flashes.
