Isoflavones are a type of naturally occurring isoflavonoids, many of which act as phytoestrogens in mammals. Isoflavones are produced almost exclusively by the members of the Fabaceae (i.e., Leguminosae, or bean) family. Although isoflavones and closely related phytoestrogens are sold as dietary supplements, there is little scientific evidence for either the safety of long-term supplementation or of health benefits from these compounds. Some studies have identified potential risks from high intake of isoflavones, such as in women with a history of breast cancer, but this concern has not been substantiated with high-quality clinical research.
Functions and Applications
1. On the relief of menopausal symptoms: menopausal women, due to ovarian dysfunction, decreased level of estrogen in vivo, cause the function adjustment of different organs does not adapt, a series of symptoms appear, and estrogen can achieve the prevention and treatment of this disorder to.
2. Regarding the prevention of osteoporosis in elderly women: ovarian function recession after a drop in estrogen levels, negative balance of bone metabolism, bone loss, osteoporosis incidence rate is much higher than the male, isoflavones can be combined with estrogen receptor on bone cells, reduce bone loss, and increase the body's absorption of calcium, increase bone density.
3. On the prevention of cardiovascular and cerebrovascular diseases: there is evidence that soy isoflavones can reduce low density lipoproteincholesterol (LDL) in reducing when cholesterol (bad cholesterol), without reducing the high density lipoprotein (HDL) cholesterol (good cholesterol).
