The Human Metabolism of Nuts Proanthocyanidins does not Reveal Urinary Metabolites Consistent with Distinctive Gut Microbiota Metabotypes

Abstract

The metabolism of PAs does not reveal urinary metabolites consistent with distinctive gut microbiota metabotypes. The quantitative excretion of metabolites is inadequate to stratify individuals due to the strong influence of external factors (source, quantity, and time of the last intake of PAs, etc.).
