Cocoa antioxidant sweetens cognition in elderly .


Flavanols in very high doses helped people distinguish patterns in a small study

Chocolate bars

High doses of cocoa flavanols may aid performance in certain memory tasks. But these antioxidants are removed during chocolate processing.

Alas, the study does not support eating chocolate. Most flavanols are removed during chocolate processing, and the study’s dose was more than 10 times as high as the flavanol levels in most dark chocolates.
