Gut health clues: diabetes study tracks plant compound breakdown
NCT ID NCT06810635
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at how people with type 2 diabetes break down polyphenols—natural compounds found in plants—compared to healthy individuals of the same age. Researchers will measure polyphenol levels in urine after participants take a special pill. The goal is to understand how gut bacteria and digestion affect these processes, which may help improve dietary advice for diabetes management.
