Urolithins from Walnuts Are Associated with Cognitive Performance: Ancillary Results from the Walnuts and Healthy Aging (WAHA) Randomized Trial

Urolithins, microbiota-derived metabolites of ellagitannins, phenolic compounds abundant in walnuts, possess anti-inflammatory and antioxidant properties that might mitigate neuronal damage. However, clinical data supporting their effects on cognition are limited.In participants in the Walnuts and Healthy Aging (WAHA) trial, we determined urinary urolithin concentrations and examined their association with cognitive performance.The WAHA study was a […]
