1, estrogenic activity. Soybean isoflavones can play an estrogen-like or antagonistic role in vivo, and can play a role in regulating estrogen receptors. Soybean isoflavones can improve perimenopausal syndrome. Postmenopausal women can effectively reduce the number of hot flashes and obviously improve perimenopausal symptoms by supplementing soybeans or soybean extracts for more than 3 months every day.
2. Antioxidant effect. The antioxidant effects of soybean isoflavones are mainly manifested in inhibiting the production of oxygen free radicals, inhibiting the production of hydrogen peroxide, reducing the oxidative damage of DNA and inhibiting lipid peroxidation.
3. Improve postmenopausal osteoporosis. Soybean isoflavones or their metabolites show a weak estrogen effect in postmenopausal women, and combine with estrogen receptors in osteoblasts to enhance the activity of osteoblasts, promote the production and secretion of bone matrix and bone mineralization, thus improving osteoporosis.
4. Reduce the risk of breast cancer. Soybean isoflavone may reduce the risk of breast cancer by increasing estrogen metabolism to 2- hydroxyestrone (an anticancer product). It can also inhibit the occurrence and development of cancer by resisting oxidation, promoting apoptosis and inhibiting cell proliferation.
5. Effects on cardiovascular system. The decrease of estrogen level in postmenopausal women leads to abnormal metabolism of fat and cholesterol, while the increase of blood lipid and cholesterol leads to an increase in the incidence of cardiovascular diseases. Soybean isoflavones can prevent and treat cardiovascular diseases through estrogen-like effects.
