The flavanols in cocoa could offer significant cardiovascular benefits for men and women over 50. A new study has determined that drinking a flavanol-rich cocoa drink improved blood vessel function, especially for older study participants.
For the current study, which was partially supported by a grant from Mars, Incorporated, 15 adults under age 50 and 19 adults over age 50 drank the specially-made beverage daily for four to six days. Researchers then tracked changes in the function of their arteries.
There was significant improvement in vessel function for all study participants, but the older men and women showed more pronounced improvement. This could be an indication that chocolate may be a very useful dietary approach to improving endothelial functioning among older adults.
There are numerous studies demonstrating that cocoa flavanols improve blood circulation and reduce the tendency to form damaging clots. However, an editorial accompanying the current study cautioned that not all chocolate contains high quantities of cocoa flavanols.
They warned that, "The flavanol-rich cocoa products used in experimental studies ... should not be confused with a number of commercially available snacks that contain many calories but are low in natural cocoa and flavanols."
