CHICAGO, Nov. 24 (Xinhua) -- The brains of healthy adults recovered faster from a mild vascular challenge and performed better on complex tests if the participants consumed cocoa flavanols beforehand, according to a study posted on the website of the University of Illinois (UI) on Tuesday.

The researchers recruited adult nonsmokers with no known brain, heart, vascular or respiratory disease, and tested the 18 participants in two separate trials, one in which the subjects received flavanol-rich cocoa and another during which they consumed processed cocoa with very low levels of flavanols. Neither the participants nor researchers knew which type of cocoa was consumed in each of the trials.
