5. Dark chocolate
Dark chocolate is full of neuroprotective flavonoids which benefit the health of the brain by promoting brain plasticity and helping your brain cells live longer. These flavonoids enhance cerebral blood flow which helps to improve attention span, memory, problem solving capabilities and reaction time.[14] The flavonoid epicatechin found in cocoa and dark chocolate helps to improve various cognitive functions.[15] One study has shown that consumption of dark chocolate improved performance on cognitive tests which included the abstract reasoning test, the scanning and tracking test, the working memory test, the visual-spatial memory test, and the organization test.[16]
What to do: Snack on 1.5 to 3 ounces of 70% dark chocolate a day to give your brain a healthy boost.
