In a study funded by Kellogg’s and carried out by the American Health Foundation, researchers reported yesterday in Nutrition that women who eat a lot of bran may reduce their chances of getting breast cancer.
Fiber-rich wheat bran lowers estrogen levels in the blood by about 10-20%, so increasing bran intake by 10-20 grams per day “may have an important health benefit,” said Dr. David Rose, the study’s lead author. The National Institutes of Health reported in 1990 that lowering blood estrogen by 17% could reduce breast cancer risk by four or five times.
