6. Dark chocolate
A huge mood booster that makes people feel good and happy. Research has shown that dark chocolate with over 70 % cocoa content has the highest flavonoid content compared to other types of milk chocolates, and these flavonoids improve cognitive functions especially memory and mental tasks. The darker the chocolate, the better it is, although it could taste too bitter for some people.
It contains the compound tyramine responsible for the increased levels of dopamine that activates our reward centers in the brain, making us feel good. Cocoa also contains stimulant substances like caffeine and theobromine that improves brain function and concentration.
