Feasibility and Colorectal Benefits of Pulses Supplementation

Beans are a forgotten staple food that shows promise in improving health. The goal of this study is to look at how bean supplementation affects metabolic and bowel health. In the long-term, the investigators believe this research will lead to a better understanding of the impact of beans on bowel health. The investigators also hope that this research study will help us understand ways to improve human diet and prevent colon cancer in the future.
