Fiber Lowers Breast Cancer Risk
A follow-up of the U.K. Women’s Cohort Study involving more than 35,000 women found that pre-menopausal women who ate 30 grams of fiber a day had half the risk of breast cancer compared with those who ate less than 20 grams per day. In addition, high protein consumption and low vitamin C intake were associated with increased breast cancer risk among pre-menopausal women. Researchers suspect that since estrogen levels are higher in pre-menopausal women, dietary fiber earlier in life may be more important for regulating female hormones and lowering breast cancer risk. Fiber helps the body remove excess hormones, carcinogens, and toxic compounds. Fiber is not present in animal products, but is found in virtually all plant foods: whole grains, legumes, vegetables, and fruit.
