Mastocytosis is the most common breast disease in women. Soy products are very nutritious and soy milk is good for protecting breast health, but sometimes some women hear the words that it is better not to drink soy milk when they have mastopexy. In the end, can I drink soy milk for breast enlargement? Theoretically, soybeans contain soy isoflavones, a kind of phytoestrogen. Women who drink soy milk regularly have significantly lower levels of the female hormones estrogen and luteinizing hormone in their bodies. High concentrations of estrogen are known to be associated with breast cancer, so many people believe that drinking soy milk causes high levels of estrogen in the body, which is a one-sided statement. According to research, women who regularly drink soy milk have significantly lower estrogen and luteinizing hormone in their bodies. Soy has a natural hormone called isoflavone, which is very similar to female hormones in the human body, and its effect is very similar to an estrogen fighting drug, so it has an anti-estrogen effect. Therefore, soybeans and soy products can change the secretion of hormones in the body and have the effect of balancing estrogen in the body. When the body estrogen is too high, soybeans and soy products will reduce it, so it is possible to drink soy milk when you have breast enlargement.
