Overview
This cross-sectional study seeks to characterize the overall polyphenol metabotype in patients with T2DM in comparison to age-matched individuals without diabetes. Additionally, the study aims to identify factors that influence the polyphenol metabotype (transit time and gut microbial capacity to degrade polyphenols in particular).
