Add some dark chocolate to your diet
When you eat chocolate you activate the systems in your brain that pump dopamine, an important brain chemical. These systems enable learning and memory, and help keep your brain sharp and fit. Chocolate also offers flavanols, brain-boosting antioxidant compounds that are also found in red wine and berries. To get the maximum brain boost from chocolate, look for the darkest chocolate available, with the least added sugar or other ingredients.
