It is now well known that one of the most prominent causes of breast cancer, as well as many other hormone related health problems in both men and women, is excessive estrogen exposure from both endogenous and exogenous sources. Improving estrogen metabolism can be of benefit in women with various conditions and family histories, including a family history of breast, uterine, or ovarian cancer, and conditions such as endometriosis, premenstrual syndrome, uterine fibroid tumors, fibrocystic or painful breasts, cervical dysplasia, and systemic lupus erythematosis. Beneficial modulation of estrogen metabolism can be accomplished through dietary and lifestyle modifications such as increasing fiber and reducing fat, increasing phytoestrogen intake, losing weight, and increasing exercise. In addition, many nutrients effectively reduce estrogen load by supporting preferred pathways of estrogen metabolism and detoxification. These include isoflavones, indole-3-carbinol, B vitamins, magnesium, limonene, calcium D-glucarate, and antioxidants. The influences of these nutrients on estrogen metabolism may have profound significance for diseases and conditions in which estrogen plays a role in clinical expression.
