Bean smoothie study hopes to unlock colon cancer prevention secrets
NCT ID NCT06032104
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at how adding beans to the diet affects bowel and metabolic health in 25 overweight adults aged 30-80 who are scheduled for a colonoscopy. Participants will drink a bean smoothie for two weeks, and researchers will measure changes in gut bacteria, blood markers, and colon tissue. The goal is to understand if beans can help prevent colon cancer in the future.
