Because they interact with estrogen receptors, soy isoflavones have also been studied for preventing menopausal symptoms and premenstrual syndrome.Click to see full answer. Correspondingly, what are the benefits of soy isoflavones?Isoflavones are well known phytoestrogens – active substances derived from plants that have a weak estrogen-like action. Isoflavones from soy have been reported to provide a number of health benefits, including the promotion of heart health and the maintenance of bone health in post-menopausal women.Beside above, what foods contain soy isoflavones? Soy Protein Isoflavones are a type of polyphenol found in legumes, including soybeans, chickpeas, fava beans, pistachios, peanuts, and other fruits and nuts (USDA, 2008). Soybeans are the richest source of isoflavones, and soy foods and ingredients contain varying concentrations of isoflavones. Furthermore, what are the side effects of soy isoflavones? Most of the side effects of isoflavones are associated with long-term use of supplements and not from dietary sources such as soy products. Common side effects may include: GI upset. Constipation, bloating and nausea. Allergic reactions (involving rash, itching, and in severe instances, anaphylaxis) Loss of appetite. Do soy isoflavones increase estrogen?Soy is unique in that it contains a high concentration of isoflavones, a type of plant estrogen (phytoestrogen) that is similar in function to human estrogen but with much weaker effects. Soy isoflavones can bind to estrogen receptors in the body and cause either weak estrogenic or anti-estrogenic activity.
