The effects of a (poly)phenol‐rich food intervention on markers of exercise‐induced inflammation and oxidative stress: A randomised controlled trial

open access: yesExperimental Physiology, EarlyView.
Abstract This study examined whether consuming a (poly)phenol‐rich food before strenuous muscle‐damaging exercise can modify post‐exercise markers of inflammation and oxidative stress. Using a double‐blinded, randomised, placebo‐controlled, between‐subjects design, 26 recreationally active males (n = 15) and females (n = 11) consumed higher‐(poly ...

The gut microbiota metabolite urolithin A, but not other relevant urolithins, induces p53-dependent cellular senescence in human colon cancer cells

open access: yesFood and Chemical Toxicology, 2020
The promotion of senescence in cancer cells by dietary (poly)phenols gained attention as a promising chemopreventive strategy against colorectal (CRC) and other cancers. Urolithins (Uros) are ellagitannins and ellagic acid-derived gut microbiota metabolites that reach high concentrations in the human colon.
