Bean Briefs: Fall 2014
January 26, 2015The influence of protein on breast cancer has been frequently studied over the years; a high protein intake can increase insulin-like growth factor, which may affect breast cancer risk.

This research team realized that most studies have looked only at women in mid-life or older, while studies that have included younger women suggest a stronger connection. Therefore they sought to discern the difference between pre- and postmenopausal women and protein intake, as well as to separate out the effects of different sources of protein.
