Flavanols Trigger Brain Activity for Memory Through Their Astringency
Flavanols, found in cocoa, red wine, and berries, trigger brain activity for memory and stress response due to their astringent taste.
Flavanols are plant-derived compounds with antioxidant properties, but their health promotion mechanism was unclear due to poor bioavailability.
A new study revealed the mechanism of action of dietary flavanols via the brain-gut axis, showing that a single oral intake stimulates brain regions involved in memory and sleep-wake regulation.
This intake also increases sympathetic nervous activity, a stress response, which may lead to future applications such as next-generation foods.
The astringent taste of flavanols has been shown to trigger brain activity for memory and stress response.Author's summary: Flavanols affect brain activity.
