Soy isoflavones are a kind of phytoestrogens, also known as phytoestrogens, which are natural hormones. Isoflavones are one of the flavonoids. They are mainly found in legumes and are formed during the growth of soybeans. Class secondary metabolites. The estrogen effect of soybean isoflavones affects hormone secretion, metabolic biological activity, protein synthesis, and growth factor activity. It is a natural cancer chemopreventive agent that can make up for the deficiency of female estrogen secretion after the age of 30, and improve skin moisture and elasticity Condition, relieve menopausal syndrome and improve osteoporosis.
Physiological effect :
1. Relieve symptoms of menopause
When entering menopause, the ovarian secretion of estrogen decreases and causes many uncomfortable symptoms. For people with menopausal syndrome, supplementation of synthetic estrogen has been used for decades to relieve symptoms, but a large number of medical practices have confirmed that long-term use of estrogen increases the risk of breast cancer and uterine cancer, which puts menopausal women in a dilemma The situation. The soy isoflavones have the effect of estrogen, so they can delay and reduce menopausal syndrome, but they are not "real" estrogen, so they can avoid the side effects of using estrogen.
2. Regulate estrogen and prevent gynecological tumors
Studies have confirmed that in addition to showing estrogen effects, isoflavones can sometimes also exhibit anti-estrogen effects. The premise is the hormone levels of the eaters themselves: for people with low ovarian function and too little estrogen secretion, it appears as estrogen. For those who secrete too high estrogen, it shows anti-estrogen effect. The mechanism is that isoflavones occupy the position of estrogen receptor through "competition" and prevent estrogen from exerting its full effect, so it can alleviate Symptoms such as dysmenorrhea and heavy bleeding in patients with endometriosis. Because the active effect of soy isoflavones is only 2% of the estrogen in the body, it can reduce the adverse reactions caused by excessive estrogen and prevent the occurrence of related cancers by reducing the effect of human estrogen. Moreover, isoflavones themselves have the effect of normalizing cancer cells and inhibiting tumor formation, so they have a good function of preventing breast cancer and uterine cancer. Because soy isoflavones have the characteristics of "lower supplements, high resistance", and are a natural and very safe phytoestrogens, they can keep female estrogen at an appropriate level and keep the body in a good condition. status.
3. Prevent osteoporosis
In post-menopausal women, the secretion of estrogen in the body is reduced, which will promote the accelerated absorption of bone and make osteoporosis aggravated. Many studies have shown that soy isoflavones can inhibit bone resorption, so it has a positive effect in preventing bone decalcification. According to research findings, the main reason why the incidence of osteoporosis and fractures among Asian women is lower than that of European and American countries is that the intake of soybeans is significantly higher than that of European and American countries. Further studies have also confirmed that supplementing with calcium and vitamin D while eating soy isoflavones can improve the absorption and utilization of calcium, increase bone density, and reduce the occurrence and development of osteoporosis. Because of its mild effect and almost no side effects, it is very suitable for long-term use.
4. Delay aging
Estrogen can bind to the estrogen receptor in the skin to activate collagen. Collagen has a supporting role in the skin, and can increase the water storage capacity, and can make the skin plump. Therefore, collagen plays a very important role in protecting and maintaining the normal structure of the skin and maintaining the proper elasticity of the skin. With age, the level of estrogen secretion continues to decline, which will make the skin lose its luster, increase wrinkles, and decrease elasticity. The isoflavones have estrogenic effects, so they have the effect of delaying skin aging. At the same time, isoflavones also have anti-oxidant functions, which can remove excess free radicals in the body and reduce the damage of lipid peroxides to cells, so it has the effect of keeping the skin beautiful and healthy.
