Dietary Fiber from Whole Grains Cuts Colorectal Cancer Risk

February 16, 2012

Whole grains reduce the risk of colorectal cancer, according to a study published in the British Medical Journal. People eating three servings of whole grains each day could decrease their risk by 17 percent. One serving of whole grains is equal to one slice of whole grain bread, one-half cup of oatmeal, or one-half cup of brown rice. Whole grains contain fiber that moves intestinal contents along more quickly, dilutes carcinogens, and fosters good bacteria that help balance the digestive tract.
