2. Soybeans 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 will change the secretion of hormones in the body. Studies in clinical medicine show that soybeans 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 reduce 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 have special effects on balancing estrogen. Selenium can prevent carcinogens from combining with normal cells' deoxyribonucleic acid, 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 and so on; Zinc-containing foods include oysters, mackerel, eels, kelp, beans, sesame seeds, walnuts, etc., among which the zinc content of oysters is particularly considerable.
Extended data:
Estrogen is a kind of main female hormones, including estrone and estradiol, which are mainly produced by ovary and placenta, and a small amount is secreted by liver, adrenal cortex and breast. During pregnancy, placenta can also be secreted in large quantities, and male testis 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, the endometrium proliferates to produce menstruation. Estrogen can keep skin moist, promote skin metabolism and blood circulation, make skin tender and delicate, and also make mammary glands proliferate, producing breasts and areola, and selectively concentrate fat on breasts, thighs and buttocks, so as to 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), which are secreted by ovary, placenta and adrenal cortex. Estradiol (E2) is widely used in clinic, which has strong effect and quick absorption, but the effect is short-lived, and the action time can be prolonged after lipidation, and the activity of estriol is very weak.
