My grandma would always say to have a bit of chocolate right before a race and a test, because it would give me a little boost or stimulate. Well grandma was right, in a recent study the University of Maine found that eating chocolate  was “positively associated” with cognitive performance.

According to Vise “Habitual chocolate intake was related to cognitive performance, measured with an extensive battery of neuropsychological tests,” the study found. “More frequent chocolate consumption was significantly associated with better performance on the Global Composite score, Visual-Spatial Memory and Organization, Working Memory, Scanning and Tracking, Abstract Reasoning, and the Mini-Mental State Examination.”

Basically many of your brain functions are stimulated by chocolate or sugar, but mainly chocolate. Too much though is not a good thing!

Research shows it's the cocoa flavanols and methylxanthines that are the reasons for the better cognitive performances.
