Feasibility of Pulses Supplementation in Healthy Adults: A Feeding Study
University of California, Davis
Summary
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.
Description
Investigators are seeking adults planning for a standard of care colonoscopies (part of the participant's usual care). As part of this feeding study, a participant will be randomly assigned to either two weeks of a dry bean smoothie that the investigators will provide in addition to the participant's usual diet or continue with participant's usual diet without the bean smoothie (including the food and drink guidelines for the colonoscopy) 2 weeks before or after the participant colonoscopy. Participants' involvement in this research will also include 2 research visits plus a visit on the day…

Interventions
- Dietary SupplementDry beans
0.5 cup of Bush's Best Cannellini Beans, three times per day before meals blended into a smoothie. If interested and depending on tolerance, participants will also have the opportunity to gradually increase the bean smoothie to a maximum of 1 cup three times per day before meals during the last week of the two-week bean smoothie intervention. If patient cannot not tolerate 1.5 cup of canned cannellini bean, we will reduce per tolerance or offer the option of choosing a bean-based flour (100 gram/day, 23% fiber from Archer Daniels Midland)
