There is a news, said that Zhejiang a middle-aged man because of long-term drinking a large amount of soya-bean milk, resulting in breast development, chest growth C cup, had to go to the hospital for breast reduction surgery. Online cheerful voice, the majority of brother-in-law paper elated, running to tell each other: [Go, buy soya-bean milk machine! ] Beautify the world, but also pay for their own money, brother-in-law is really too loving, too kind. For their sake, but also for the interests and well-being of more men, we must sort out a question: Drinking soya-bean milk can really breast enlargement? Soymilk has a high nutritional value, its protein content is almost the same as that of milk, and its saturated fatty acid and carbohydrate content are lower than that of milk, and it does not contain cholesterol. It is an ideal healthy drink. Of course, the calcium and vitamin C content of soybean milk are far lower than that of milk, which is its deficiency… [Stop! My house is not interested in this! Say what matters! ] Well, don’t worry, little Lord, this is the point.
Soymilk and Phytoestrogens
When a woman reaches puberty, The mammary gland matures under the action of estrogen. In addition to genetic factors, Estrogen levels often directly determine breast size and fullness. The counterexample is that after a woman enters menopause, As estrogen levels have dropped significantly, breasts have shrunk and sagged. Soymilk contains a small amount of phytoestrogen, the main ingredient is soybean isoflavone, a compound with weak estrogen effect. Is it the main culprit causing male breast development in the news and the legendary brother-in-law’s breast enlargement weapon? Compared with estrogen secreted physiologically by human body, Phytoestrogens only have a similar molecular structure, It can combine with estrogen receptors in the body to produce estrogen-like effects, but the effect is much weaker than that of real estrogen. Therefore, in this sense, the role of phytoestrogen in the body is bidirectional: a. When the content of phytoestrogen in the body is very low, it can play a role in supplementing estrogen; B. When the phytoestrogen content in the body is very high, Because its binding to the receptor hinders the normal binding of physiological estrogen to the receptor, On the contrary, it has a inhibitory effect. It is equivalent to reducing estrogen level and weakening estrogen effect. Through the above analysis, we can get such a conclusion: for the young brother-in-law who are in full swing and secreting estrogen, drinking soya-bean milk, or supplementing phytoestrogen, cannot play a role in improving the body’s estrogen level and promoting breast development.
So, instead of drinking soya-bean milk, what about directly supplementing estrogen?
It must be explained seriously and solemnly: Although estrogen is very important for the growth and development of women and the prevention of many diseases, But high estrogen levels are also the trigger of breast cancer, endometrial cancer and other diseases. Therefore, Not only are the majority of middle-aged and young women unable to supplement estrogen at will, but even for menopausal women with very low estrogen levels in their bodies, they must be cautious and cautious in taking estrogen supplement therapy in order to relieve climacteric syndrome. Let’s return to the original news, can soya-bean milk broaden men’s [mind]? In fact, the content of soybean isoflavone in soybean milk is very small, Less than 100 g/ml, Usually drink 200 ml of soya-bean milk every day, Intake of soybean isoflavone was less than 20 mg, Even according to the man in the news, Drink 1000 ml a day, Soybean isoflavone intake is only 100 mg. Perhaps people have little perceptual knowledge of these figures, We can refer to the Dietary Guidelines for Chinese Residents compiled by the Chinese Nutrition Society. It recommends that Chinese eat 40 g of soy food every day, According to the content of soybean isoflavone 3.5 mg/g in soybean, 140 mg of soybean isoflavone in 40 g soybean food, This is certainly a reasonable and safe intake. Therefore, The simple attribute of male breast development to drinking soya-bean milk, This is lack of evidence, not rigorous enough. Clinically, Male breast development is not uncommon, Newborns, adolescents and middle-aged and elderly men can all suffer from the disease. There are also many causes of disease. For middle-aged and elderly men, Due to different degrees of testicular dysfunction, Levels of testosterone in the blood are reduced, circadian rhythms are weakened, The ratio of androgen to estrogen decreased, It may also cause breast development. Of course, long-term and large consumption of a single food will cause excessive intake of some nutrients. However, we should not blindly exaggerate the harm of soya-bean milk for the purpose of seeking novelty and attracting attention, so as to cause unnecessary panic among men and unrealistic expectations among brother-in-law. [Soya-bean milk cannot enlarge breasts! ] I can feel that the hearts of the little masters are broken.
