The Advantage of Soy Isoflavones

Numerous reports indicate that, because soy is high in isoflavones, it can prevent illness and promote good health. Isoflavones are a class of phytochemicals, which are compounds found only in plants (phyto means plant). They are also a type of phytoestrogen, or plant hormone, that resembles human estrogen in chemical structure yet are weaker. By mimicking human estrogen at certain sites in the body, isoflavones provide many health benefits that help you to avoid disease. Isoflavones are found in soybeans, chick peas and other legumes. However, soybeans are unique because they have the highest concentration of these powerful compounds. Soy contains many individual isoflavones, but the most beneficial are genistein and daidzein.

Isoflavones show tremendous potential to fight disease on several fronts. They have been shown to help prevent the buildup of arterial plaque, which reduces the risk of coronary heart disease and stroke. Isoflavones may help reduce breast cancer by blocking the cancer-causing effects of human estrogen. They may also prevent prostate cancer by hindering cell growth. Isoflavones can fight osteoporosis by stimulating bone formation and inhibiting bone resorption. They may even relieve some menopausal symptoms as well.
All these findings suggest eating soy foods, natural sources of isoflavones, can protect and enhance your overall health. Isoflavones work together with soy protein in fighting disease. Studies show that isoflavones account for approximately three-fourths of soy's protection, while its protein is responsible for about one-fourth. The best way to consume isoflavones is in food form, so that you can benefit from all of soy's nutrients and beneficial compounds. The highest amounts of isoflavones and soy protein are found in tempeh, whole soybeans (like edamame), textured soy protein, soynuts, tofu and soymilk. Researchers recommend consuming at least one to two servings a day. A serving is equal to 1 ounce of soynuts; 4 ounces of tempeh, textured soy protein (cooked), or edamame; or 8 ounces of soymilk.
For those new to soy, I recommend slowly adding it to your diet, until you develop a taste for it. In spaghetti sauces, replace ground beef with textured soy protein. Use tofu instead ricotta cheese in lasagna, or make herb dips with it in a food processor. Use soymilk to cream soups or make smoothies. People on the run can always eat soynuts. Tempeh is one of the easiest soy foods prepare. To make a grilled tempeh sandwich, just cut it into slices, sprinkle on some soy sauce, saute with sliced onions and pile it on some bread. Remember, you will only continue to eat healthy foods if they taste good. So, experiment and have fun trying out new ways to enjoy soy.
