Boston, MA – Women who eat more high-fiber foods during adolescence and young adulthood–especially lots of fruits and vegetables–may have significantly lower breast cancer risk than those who eat less dietary fiber when young, according to a new large-scale study led by researchers at Harvard T.H. Chan School of Public Health.

The study will be published online February 1, 2016 inĀ Pediatrics.
