A study has found that people who were given cocoa drinks had better working memories, higher scores in reasoning tests and improved blood sugar control than those who did not have them.
Cocoa contains high levels of flavonols which are also found in tea, grapes, red wine and apples which are thought to protect brain cells from damage.
Researchers gave 90 people with mild thinking problems, which can precede dementia, daily drinks containing large or intermediate amounts of cocoa flavonols for eight weeks.
Other flavonol containing foods were restricted to establish the dose each person was getting and they were compared with people drinking low levels of cocoa.
