What is the relationship between soy and 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.
Why does soy increase estrogen?
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. Because estrogen plays a role in everything from breast cancer to sexual reproduction, this is where most of the soy controversy stems.
Does soy increase or decrease estrogen?
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.
Does soy based protein increase estrogen?
Soy Does Not Raise Estrogen or Lower Testosterone Levels in Men. Misconceptions concerning soyfoods stem from the fact that soy is a uniquely rich source of isoflavones, which are naturally occurring plant chemicals classified as phytoestrogens.

Do soy products really contain estrogen?

Does eating soy increase estrogen?
Soy products, such as tofu, contain phytoestrogens. Soy-based products, including edamame and some meat substitutes, are especially rich in plant estrogens. Estrogens that occur in plants are called phytoestrogens. Early research raised concerns that phytoestrogens could raise estrogen levels in the body. However, they may have the opposite effect.
