Does soy milk increase estrogen?

If you like tofu, or opt for soy milk over dairy, concerns about the health effects of soy may have piqued your interest. Soy contains phytoestrogens, or plant-based estrogens. These are mainly two isoflavones, genistein and daidzein, that act like estrogen, the female sex hormone, within the body.Click to see full answer. Herein, can drinking soy milk increase estrogen?Soybeans are rich in plant estrogens and are one of the few food sources of a particular type of plant estrogen called isoflavones. Drinking just two cups of soymilk or eating one cup of tofu produces blood levels of isoflavones that can be 500 to 1,000 times higher than typical estrogen levels in women.Subsequently, question is, does soy milk affect hormones? Soy consumption has been suggested to exert potentially cancer-preventive effects in premenopausal women, such as increased menstrual cycle length and sex hormone-binding globulin levels and decreased estrogen levels. Only three intervention studies reported hormonal effects of soy isoflavones in men. In this way, does soy really increase estrogen levels? 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.Why soy is bad for males?Because soy contains phytoestrogens, men may worry about including it in their diet. However, studies do not indicate that soy negatively impacts the production of testosterone in men.
