Soybeans contain isoflavones, which are phytoestrogens, so some women hope to supplement estrogen by drinking soy milk and eating tofu.

Many men are worried that the intake of estrogen in soymilk will change. In fact, these two ideas are superfluous. The isoflavones in soybeans are only a kind of plant estrogen. The activity is very low, only millions of true estrogen activity. One to one in ten thousand, they have a two-way regulation of estrogen levels in the human body, which means that if there are too many estrogens in the body, they will seize the estrogen receptor, making some true estrogens unable to show activity. Thereby reducing the level of estrogen in the body, if the body’s estrogen is too small, they can bind to the estrogen receptor, better than nowhere to increase a little estrogen activity

However, eating soy milk, tofu or other soybeans made into soy products every day, the content of isoflavones is very small, so-called regulation of estrogen levels in the body, basically only theoretical possibilities, the actual effect is very weak.
