Generally speaking, boys drinking soybean milk will not cause precocious puberty, although some soybeans are called? Phytoestrogen? If you drink soy milk for a long time, it may lead to the accumulation of phytoestrogens in the body, but the effect of phytoestrogens in the human body is relatively small, only one thousandth of the effect of estrogen in the human body, and generally it will not cause precocious puberty in children. The content of soybean isoflavone in a cup of soybean milk is 1ug, and the daily intake of soybean isoflavone for children is recommended to be 25mg, so drinking soybean milk in moderation will not cause precocious puberty in children. But if you drink a lot of soy milk for a long time, it may still cause precocious puberty in boys. And boys drinking soy milk for a long time every day may also cause abdominal distension, gastrointestinal dysfunction and diarrhea.
So for children, drinking a small amount of soybean milk is good for their health, but if they drink a lot, they are prone to various physical discomfort.
