Soy products do not feminize men

　　Because people pay a lot of attention to soy products. On the one hand, they are relatively safe amid the tide of food problems, and on the other hand, they are rich in nutrients. Some people say that "men drinking soy milk will increase the secretion of estrogen, which will cause male female Characteristic confusion leads to the final male The main reason for this statement is that soy milk contains isoflavones, which are called phytoestrogens, and many people believe it to be true.

　　First, let’s make it clear what estrogen and phytoestrogens are.

　　Estrogen is synthesized from testosterone and androstenedione through a series of biochemical reactions. There are many kinds of estrogens, but the three types that are actually secreted by glands are l7β-estradiol, estrone and estriol. It is generally believed that estradiol is secreted by the ovary, and can also be synthesized in small amounts by the adrenal cortex and testicles. The placenta after three months of pregnancy is the main tissue that secretes estrogen. Progesterone is another type of estrogen that works synergistically with estrogen. There are many types of progestins, but the one that plays the main role is progesterone. Progesterone is produced by the corpus luteum of pregnancy, and the corpus luteum of pregnancy is produced by the placenta. It directly inhibits the function of the ovary and prevents new ovulation.

　　Women who are more affected by estrogen and develop symptoms are between the ages of 45 and 50, which is menopause. At this time, due to the decrease in female estrogen secretion, endocrine disorders will occur, temporary hyperpituitarism will occur, and other endocrine functions will be affected, resulting in menstrual cycle disorders, headaches, irritability, suspicion, emotional instability and other symptoms.

　　Isoflavones are a component in plants and are found in potatoes, cereals, grains, and vegetables. However, the highest content is found in beans and flaxseeds. Since the structure of isoflavones is similar to that of estrogen, when isoflavones enter the human body, they can occupy estrogen receptors and make the body feel that there is no lack of estrogen. Therefore, the menopausal response is weakened or eliminated. Therefore, people call plant factors such as isoflavones “phytoestrogens”. But isoflavones are not estrogen after all. They do not have the effects of estrogen on the body, nor can they prevent women from menopause The arrival of pregnancy period will not promote egg development and transport.

　　Besides, estrogen must bind to estrogen receptors to work. Males don't have many estrogen receptors, so most of the estrogen in the body is excreted in the urine. Therefore, counterfeit estrogen such as isoflavones has no effect on men at all. First, it has no receptors to bind to; second, it has no target to act on. Therefore, it is absolutely impossible for men to become feminized by eating soy products.

　　Don't believe all rumors. What is needed is scientific basis to distinguish whether it is right or wrong. Don't blindly believe in rumors. Whether growth is good or bad depends on one's own physical fitness. Slow or poor development is not caused by a certain kind of food, so you need to treat rumors calmly.
