Dark chocolate contains flavonoids, which are some of the most potent antioxidants found in nature. Benefits include a boost in memory, attention span, reaction time, concentration and problem-solving skills. It also increases blood flow to the brain. Regular consumption of moderate amounts of chocolate is also associated with less weight gain and a reduced risk of Alzheimer’s type dementia, according to research.
