Fiber-rich Foods to Treat Obesity and Prevent Colon Cancer

The study will target a population at high risk for colorectal cancer, overweight and obese participants with a history of a colon polyp in the past 3 years to test whether a high-legume, high-fiber diet will simultaneously increase weight loss and suppress intestinal biomarkers of cancer risk compared to a control diet (healthy American). In addition, it will explore potential mechanisms through which the high-legume intervention diet facilitates weight loss and intestinal health.
