“We now have emerging evidence that cocoa flavanols may improve cognitive function in some people, though this is still a very early area of research,” said Mars Symbioscience Researcher Catherine Kwik-Uribe.

However, another similar study found no benefits of consuming flavanols; so while some evidence exists, more tests are needed.
