Soy isoflavones can bind to estrogen receptors in the body and cause either weak estrogenic or anti-estrogenic activity. The two major soy isoflavones are called genistein and daidzein.
What is estrogenic activity?
A chemical having estrogenic activity (EA) mimics human estrogen, by binding to the cell’s normal estrogen receptor location. … Chemicals with estrogenic activity EA are the most common subset of endocrine disrupting chemicals (EDC).
What are weak estrogens?
Estriol is considered a weak estrogen as well. It has been postulated that estrone is a “bad” estrogen and may be the cause of estrogen’s cancer-causing properties, while estriol is a “good” estrogen and may protect against cancer. Estradiol is probably neutral.
