Can drink soymilk cause cancer?

Business news on January 29: "drinking soy milk may cause cancer?" This view has been popular in the market for a long time, because soy products contain a lot of phytoestrogens, which may cause breast cancer in women; women who have breast cancer are afraid to drink soy milk, which may aggravate their condition, etc However, a large survey report published in the latest issue of the American Journal of clinical nutrition recently completely denied these claims A large-scale investigation involving 9514 breast cancer patients from China and the United States with the participation of Shanghai CDC for an average of 7.4 years found that soy isoflavone intake not only does not cause cancer, but also helps to reduce the risk of recurrence and death of breast cancer Zheng Ying, director of cancer prevention and treatment department of Shanghai CDC, told the media that soy products are one of the main sources of protein for Chinese women, while American women seldom eat soy products, so the impact of the difference in soy products intake on the prognosis of breast cancer attracted the interest of researchers from both China and the United States Zheng said that China's breast cancer patients accounted for 5042 of the patients who participated in the survey, and the center has followed up these people since 2002 until June 2009 In the study, they found that those with the highest soy protein intake had a 29% lower risk of death and a 32% lower risk of breast cancer recurrence than those with the lowest soy protein intake Subsequently, the Shanghai CDC released the above data The survey group clearly found that the intake of soy products can significantly reduce the risk of breast cancer recurrence and death Women with tender feelings like water can have all kinds of verve, and estrogen is indispensable Estrogen, which acts on the ovaries, uterus, vagina, breasts and other parts, makes women have graceful demeanor and protects them from diseases But estrogen is also a double-edged sword, more and less are dangerous to women's health, especially the high level of estrogen, which has become one of the factors inducing breast cancer This is also why there are rumors that drinking soy milk may cause breast cancer Wan Donggui, chief physician of the Department of Integrated Chinese and Western medicine and oncology, China Japan Friendship Hospital, Ministry of health, told the life times that the phytoestrogens in bean products are not equal to human estrogens Phytohormone has a molecular structure similar to human estrogen, which can combine with estrogen receptor α (ER α) and estrogen receptor β (ER β), and produce a similar effect with estrogen However, isoflavones in soybean preferentially bind to estrogen receptor β (ER β) instead of estrogen receptor α (ER α) through trans action, which leads to the structural change of estrogen receptor and produces selective estrogen receptor modulators (SERMs), so as to play the role of treatment and prevention of breast cancer In other words, the receptor targets of the two estrogens are different, so it is unnecessary to worry that drinking soy milk will lead to breast cancer In fact, as published in the June 2008 issue of the Journal of nutrition, the leading Asian Journal of medicine shows that Asian women can reduce the incidence rate of 1/3 breast cancer by drinking soybean milk Wan Donggui finally added that there are many ways to eat soybean products If you drink about 800-1200 ml of soybean milk every day, you can reach the standard of 30-50 g of soybean per day recommended in the dietary guide for Chinese residents.
