The following video is a highlight from our October 2014 Campbell’s Office Hours Webinar provided for current and past students. Dr. Thomas M. Campbell reviews three large human intervention trials that have been used as evidence that diet is not likely to be related to breast cancer. Take a look under the hood, however, and see exactly what dietary changes were being studied, and what is still left to study. Dr. Campbell concludes that important hypotheses involving a whole-foods, plant-based diet have not been investigated and more research is necessary.
