HUNTINGTON, W.Va., Sept. 2 (UPI) -- Mice that ate a modest amount of walnuts as part of their regular diet had a significant decline in breast cancer risk, U.S. researchers say.
Study leader by Elaine Hardman of Marshall University's Joan C. Edwards School of Medicine compared the effects of a typical diet and a diet containing walnuts across the lifespan of the mice -- through the mother from conception through weaning and by eating the food directly.
