Estrogen is a natural steroid hormone found in the female reproductive system. Most of the estrogen in a woman's body is produced by the ovaries and in small amounts by other tissues, including the brain, fat tissue and skin. The hormone estrogen regulates the menstrual cycle and promotes healthy bones. Many breast tumors are driven to grow by the naturally occurring hormone estrogen. Thus, estrogen increases the risk of developing breast cancer significantly, notes Cornell University. Many epidemiology studies indicate that high intake of dietary fiber may help reduce blood levels of estrogen.
Whole Grains
Whole grains are a diet rich in natural fiber. High-fiber diet has an effect on the main female hormone estrogen. The dietary fiber in whole grains modifies serum estrogen concentrations by lowering overall energy intake, according to the University of California. Some researchers have found that excess estrogen plays a role in the development of hormone-dependent breast cancer. Thus, eating whole grains on a regular basis can also help lower risk for breast cancer in women.
Saw Palmetto
Saw palmetto, a palm-like plant, is endemic to the southeastern United States, particularly in Florida. Its berries include therapeutic agents. Saw palmetto is being used with increasing frequency for the treatment of high serum estrogen levels in postmenopausal women. The findings suggest that saw palmetto exerts its anti-estrogenic effect by inhibition of estrogen receptors, according to MedlinePlus.
Cauliflower
Cauliflower is a cruciferous vegetable. It contains an indole-3-carbinol (I3C), which is a promising anti-tumor agent. It has been known that I3C controls the production of malignant estrogen by changing the process by which the body biosynthesizes estrogen, according to the Oregon State University. The observers also note that the dietary I3C found in cruciferous vegetables, like cauliflower, is also effective in helping to combat or slow down estrogen-induced breast cancer.
