It's Easter time, and here is something to consider for all of the chocolate lovers.

Consumption of a cocoa drink rich in flavanols—a substance found in dark chocolate—gives the brain a boost of blood flow for two to three hours, a University of Nottingham study has found.

The increased blood flow could enhance performance, lead researcher Ian McDonald, professor of metabolic physiology, says. It can also improve general alertness. The study raises the possibility that ingredients of chocolate could be used to treat vascular impairment, such a strokes or dementia, and for maintaining vascular health.

The study also points to possibly using cocoa flavanols to enhance brain function when people suffer fatigue, sleep deprivation and the effects of aging. McDonald emphasised that the level of cocoa-rich flavanol beverage was specifically designed for the study and not available commercially.

Flavanols are also found in red wine, green tea and blueberries.
