After women enter puberty, the mammary glands mature under the action of estrogen. In addition to genetic factors, estrogen levels often directly determine the size and fullness of breasts. The counterexample is that after women enter menopause, their breasts shrink and droop due to the significant drop in estrogen levels.

Compared with estrogen secreted by human body, phytoestrogens have similar molecular structure and can combine with estrogen receptors in vivo to produce estrogen-like effects, but their effects are far weaker than real estrogens.

The effect of phytoestrogens in the body is two-way. When the estrogen content in the body is very low, estrogen can be supplemented. When the content of estrogen in the body is high, its combination with the receptor hinders the normal combination of physiological estrogen and the receptor, thus producing an inhibitory effect, which is equivalent to reducing the level of estrogen and weakening the role of estrogen.

Therefore, drinking soybean milk, or supplementing phytoestrogens, can not improve the level of human estrogen and promote breast development.

Extended data:

It is best not to drink soy milk in six situations.

1, people with cold soybean milk, indigestion, belching and poor renal function, it is best to drink less soybean milk. In addition, patients with acute gastritis and chronic superficial gastritis should not eat soy products, so as not to stimulate excessive gastric acid secretion to aggravate the condition or cause flatulence.

2. Soymilk with brown sugar is not easily absorbed by human body. Because there are many kinds of organic acids in brown sugar, which combine with protease in soybean milk, this phenomenon will not occur when white sugar is added.

3. The thermos and the soy milk that has been kept warm in the thermos are not suitable, because the warm and humid environment in the thermos is very conducive to bacterial reproduction. In addition, soap toxins in soybean milk can dissolve the scale in thermos bottles, which is harmful to human health.

4. Because soybean milk is made of soybean and contains high purine content, it belongs to cold food, and people with gout symptoms, fatigue, physical weakness, mental fatigue and other symptoms are not suitable for drinking soybean milk.

6. Boil soybean milk with cover. Soymilk should not only be cooked, but also the pot cover should be opened when it is cooked, because only by opening the pot cover can the harmful substances in soy milk evaporate with water vapor.
