Here's something chocolate lovers will want to hear. Chocolate may help boost brain power.
A new study suggests that consuming more flavanol, a component of cocoa, improves cognitive function and blood pressure in elderly patients who have mild cognitive impairment.
In the study, elderly patients with mild cognitive impairment consumed drinks that were either low, intermediate or high in cocoa flavanol. Cognitive function - including executive function, short-term and long-term memory, processing speed and overall thinking skills - was tested after eight weeks. Scores improved in patients who drank intermediate and high levels of flavanol.
