Both studies on wine and chocolate revealed that polyphenols released by them help oxygenate the brain better and even makes the body stronger. Researchers think that both of them consumed together could work wonders and double the effectiveness.
The first team of researchers to test the polyphenols extracted from wine and their effects on the human body were from the University of Northumbria. There were 75 volunteers selected by this team. All of them had to take math tests before receiving the polyphenol resveratrol pill. Later, an MRI scan revealed that their blood flow was “significantly higher” than the normal rates. The first tests were successful and revealed an increase in the volunteers’ cognitive abilities but the results were not final. Another experiment was undertaken which was comprised of 24 volunteers. They were given a similar pill but this time it contained an extract of cocoa, which is the basic ingredient for making chocolate. All 24 test subjects immediately shown improvements in accuracy and in speed when it came to solving math tests.
Emma Wightman and Crystal Haskell, two scientists from the University of Northumbria who carried out the experiment, believed that both wine and chocolate merged together to be consumed can be the most effective tool to enhance one’s memory. Ms Wightman, who is a psychologist, said that the improved blood flow caused by the release of polyphenols will be most appreciated especially by elderly people. She said:
There is a natural reduction in blood supply around the brain as people get older so anything that increases it should have a positive effect. Our tests were on young students whose cognitive abilities would be at their peak. They are less likely to see an improvement. We are now carrying out studies on older volunteers.
The recommended wine was Merlot but all types of chocolates based on cocoa plant extractions were welcomed. Scientists only studied the effects of polyhenols only on larger quantities but their aim still remains the study of those smaller quantities that can make a difference.
