Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Intestinal bacteria can metabolize unabsorbed polyphenols (plant compounds) to produce smaller molecules which may impact health. In addition, evidence suggests that this process may be affected by body fatness. This study aims to investigate absorption of blackberry polyphenols, their impact on intestinal bacteria, polyphenol metabolites formed by intestinal bacteria, and how these processes differ for obese and lean individuals. It is hypothesized that polyphenol absorption and metabolism will differ between obese and lean individuals and that differences in intestinal microbiota may play a role.
