The good news isn’t over yet. Dark chocolate may also improve the function of the brain.
One study of healthy volunteers showed that 5 days of consuming high-flavanol cocoa improved blood flow to the brain.
Cocoa may also significantly improve cognitive function in elderly people with mental impairment. It also improves verbal fluency and several risk factors for disease.
Cocoa also contains stimulant substances like caffeine and theobromine, which may be a key reason cocoa can improve brain function in the short term.
