Grapes May Boost Skin’s UV Defense Through Gene Changes
TL;DR Summary
A small study of four volunteers found that consuming about three servings of grapes daily for two weeks altered gene expression in skin cells, promoting UV-protective changes (keratinization and cornification) and reducing the oxidative stress marker malondialdehyde, suggesting grapes may confer UV protection via nutrigenomic effects; the mechanism is still unclear and findings are early, with prior data and funding from the California Table Grape Commission noted.
