Hot chocolate or even a piece of dark chocolate might seem to be the quickest remedy for your bad mood, but does the brain have anything else to do in the process? Some studies investigated the effect of cocoa flavanols, a kind of chemical compound naturally present in cocoa, which could affect not only the blood flow but also the mood and cognitive functions. A few clinical studies have shown improvements in mental fatigue, mood, or cognitive function.
However, there is a major caveat: cocoa is not an officially recognized brain boosting supplement, and the effects observed in the studies do not necessarily apply to all chocolates.
