Soy milk is a common drink in daily life. It is said that soy milk contains "soy isoflavones", a type of estrogen. Men who drink it will develop breasts, stop growing beards, become effeminate, etc. Feminine characteristics, so not suitable for drinking. Regular drinking of soy milk is beneficial to reducing the risk of cardiovascular and cerebrovascular diseases, and is beneficial to prolonging the life of middle-aged and elderly people. However, another rumor says that regular drinking of soy milk is bad for male citizens. The most direct reason is that it will cause premature aging and memory loss. It can even cause sexual dysfunction. It is a misinformation that men cannot drink soy milk. It is said that soy milk contains soy isoflavones, a type of estrogen. Men who drink it will develop breast development, lose beards, become effeminate and other feminine characteristics, so they should not drink it. In fact, the statement that men cannot drink soy milk is ridiculous and purely misinformation. First of all, soy isoflavones are substances similar to hormones. They are similar to estrogen in structure and properties. They have the ability to bind to estrogen receptors in the human body, so they have always been called phytoestrogens. This type of phytoestrogens is different from pharmaceutical estrogens. Drug estrogen has a one-way effect on the human body, directly increasing hormone levels. The phytoestrogens in soy products have a two-way effect on the human body. When the human body is deficient in estrogen, it can be supplemented; when the human body is not deficient in estrogen, phytoestrogens have positive physiological effects such as antioxidants. Since the biological activity of phytoestrogens is only one thousandth of that of pharmaceutical estrogen, for young women, a cup of soy milk a day is not enough to cause significant changes in estrogen levels. For men, the phytoestrogens in soy milk are unlikely to reverse hormone balance, let alone affect male sexual characteristics, or affect the normal development of boys. Soy milk is rich in plant protein, calcium, vitamins and other nutrients, which can regulate the function of the female endocrine system. It is also one of the best foods for men to prevent osteoporosis. Drinking soy milk in an appropriate amount is beneficial and harmless. Eating soybeans in an appropriate amount is beneficial and harmless to men. Because there is an estrogen receptor in the female body, soy isoflavones can exert an estrogen-like effect after binding to this receptor. This receptor does not exist in men, so the isoflavones in soy milk have no effect on men. Menopausal women who lack estrogen should eat more than 50 grams of dry beans or an equivalent amount of soy products every day to supplement estrogen and partially compensate for the effects of reduced estrogen levels, such as weakened skin elasticity and accelerated bone calcium loss. , rapid heartbeat, facial flushing, irritability and other problems. Therefore, soy products are very beneficial to middle-aged and elderly women, and they will certainly not change hormone levels for men. Don’t eat too much of any food. Nutritious soy products may not be suitable for everyone. First of all, soybeans contain high purine content, which is not suitable for gout patients. Patients with acute gastritis and chronic superficial gastritis should not consume soy products to avoid stimulating excessive gastric acid secretion, aggravating the condition, or causing gastrointestinal flatulence. Beans contain a certain amount of oligosaccharides, which can cause belching, bowel sounds, bloating and other symptoms, so friends with gastric ulcers are best to eat less. Patients with gastritis and renal failure need a low-protein diet. Beans and their products are rich in protein, and their metabolites will increase the burden on the kidneys, so they should be fasted. The oxalate in beans can combine with calcium in the kidneys, easily forming stones, and aggravating the symptoms of kidney stones, so patients with kidney stones should not eat them.
