Taste-triggered brain boost: astringent flavanols may wake the mind

New mouse study suggests the dry, astringent sensation of flavanols found in foods like cocoa and berries can directly signal the brain, activating attention, learning, and memory pathways through sensory nerves and stress systems—producing effects similar to a mild workout—despite flavanols' low bloodstream presence. This points to sensory nutrition as a potential way to design foods that couple taste with brain benefits.
