Dietary phytoestrogens in the prevention of long‐term postmenopausal diseases

Phytoestrogens (PEs) are natural compounds, with a biological activity like estrogen, which comprise isoflavones, lignans and coumestans. A traditional Asiatic phytoestrogen-rich diet is associated with a lower incidence of breast cancer and postmenopausal illness, and much evidence indicates that PEs prevent bone resorption, increase bone density and reduce cholesterol. The estrogenic effects of phytoestrogens can be useful in preventing postmenopausal osteoporosis and cardiovascular disease.
