Drinking Cocoa May Improve Blood Flow in Brain

BBC News Health reports that a new study in Neurology has found a connection between cocoa consumption and improved blood flow to the brain. The study involved 60 people with an average age of 72, some of whom had normal blood flow to the brain, and some of whom had poor blood flow, as determined by ultrasound. Due to the belief that a compound called flavanol could be the compound responsible for improved blood flow, half of the participants were given flavanol-rich cocoa and half were given flavanol-poor cocoa. Results showed that the amount of flavanol did not affect blood flow but that 88% of people who started with poor blood flow showed improvements in blood flow and some cognitive tests, while only 37% of patients who began the study with normal blood flow showed improvements, indicating that there may be some other compound in cocoa causing the effect.
