Soy products are beneficial to cardiovascular and overall health because of their high content of polyunsaturated fats, fiber, vitamins, and minerals, low content of saturated fat, and biologically active compounds called phytochemicals.1
The three major isoflavones found in soybeans are genistin, daidzin, and glycitin. Soy isoflavones exert both estrogenic and anti-estrogenic effects, depending on the tissue in which they are acting. They are structurally similar to 17-estradiol, a mammalian estrogen, and are thus called phytoestrogens. They also have non-hormonal effects, including signal transduction and antioxidant activity. Soy isoflavones may inhibit bone resorbption and help stimulate bone formation,2 without the side effects of hormone replacement therapy.
In recent years there has been an increase in the number of basic science, clinical, and nutritional studies investigating the potential health effects of phytoestrogens.3 Genistein is the most abundant phytoestrogen, derived almost entirely from soybeans, and is proposed to be the most biologically active. In postmenopausal women in the U.S., the daily intake of genistein is only about one mg per day.4 The Japanese however, who consume about 50 mg per day, are the longest-lived people in the world.5
Ultra Soy Extract has been reformulated to include organic, non-GMO Soynatto® fermented soy food. Ultra Soy Extract now contains an even higher ratio of genistein/genistin to other isoflavones. Numerous studies have found benefits associated with increased consumption of fermented soy.
Scientists collecting data on isoflavones in soy found fermentation enhanced the bioavailability of soy products (miso and natto), allowing them to have significantly greater amounts of the more active aglycone forms (not bound to a sugar) such as genistein than do unfermented soy products such as soybeans, soy milk, and tofu. |
