Before you pass up that candy bar listen up.
Chocolate may help sharpen your mind.
Researchers used MRI brain scans to show how drinking cocoa rich in flavanols, boosts blood flow to key areas of the brain.
However, the level of cocoa flavanols used in the study was much higher than what is available commercially.
But if you still want to indulge, dark chocolate is especially rich in flavanols, as are red wine, green tea and blueberries.
