2. Soybean and bean products contain a lot of phytoestrogens, which play an important role in the treatment and prevention of breast cancer. The key point is that soybeans can change the secretion of hormones in the body. Clinical medical research shows that soybean and bean products have the function of balancing estrogen in the body. When the estrogen in the body is too low, soybeans or bean products will increase it, but when the estrogen is too high, soybeans or bean products will also decrease it.
3. Vitamin D is related to hormones. The higher the vitamin D content, the lower the mortality rate of breast cancer. Because the circulation of vitamin D in the blood protects the female body to a certain extent, it can prevent the occurrence and development of breast cancer. Vitamin D mainly comes from diet, such as milk and fish. Women, if they eat 1 cup of milk and 500 grams of fish every day for a long time, can play a role in regulating the balance of estrogen.
4. Foods rich in selenium and zinc also play a special role in balancing estrogen. Selenium can prevent carcinogens from combining with DNA of normal cells, thus inhibiting the occurrence of cancer cells. Zinc has a strong inhibitory effect on various cancers in different parts of the human body. Selenium-containing vegetables include shepherd's purse, garlic, mushrooms, tomatoes, pumpkins, etc. Zinc-containing foods include oysters, mackerel, eels, kelp, beans, sesame seeds and walnuts. Among them, the zinc content of oysters is particularly impressive.
Extended data:
Estrogen is a major female hormone, including estrone and estradiol, which is mainly produced by ovary and placenta, and a little secreted by liver, adrenal cortex and breast. During pregnancy, the placenta can also secrete a lot, and male testicles can also secrete a small amount of estrogen.
After women enter puberty, the ovaries begin to secrete estrogen to promote the development of vagina, uterus, fallopian tube and ovary itself, and at the same time, endometrial hyperplasia produces menstruation. Estrogen can keep skin moist, promote skin metabolism and blood circulation, make skin tender and delicate, and also make mammary glands proliferate, produce breasts and areola, selectively concentrate fat on breasts, thighs and buttocks, make women's figure beautiful and curvy, and produce and maintain women's secondary sexual characteristics.
Natural estrogen: estradiol (E2), estrone (E) and estriol (E3) secreted by ovary, placenta and adrenal cortex. Estradiol (E2) is widely used in clinic, with strong action and quick absorption, but its action is short-lived, and its action time can be prolonged after lipidation, so the activity of estriol is very weak.
