Plant-Based Nutrition for Breast or Endometrial Cancer

This is a randomized controlled trial of a whole food, plant-based (WFPB) dietary intervention among women with metastatic breast or endometrial cancer. It is designed to explore whether this dietary intervention is sustainable in this population for 26 weeks and whether improvements in quality of life and cardiometabolic health demonstrated in a previous study are sustained. If so, this study will gather information to know whether these benefits translate into reduced overall mortality and cancer markers when compared with a control group that is matched for time and attention but does not implement dietary change. The intervention consists of a whole food plant-based dietary program, group education and individual coaching/visits while the control group gets general wellness group education and individual visits while maintaining their usual diet.
