Throughout history, cocoa has been described as a medicine for many ailments. New research suggests that cocoa may also have a beneficial effect on heart disease and stroke.
A research team in Southampton in England, led by Dr Denise O'Shaugnessy, has shown that drinking a cup of cocoa can prevent potentially fatal blood clots. Dr O'Shaughnessy will present this data at the XXth Congress of the International Society on Thrombosis & Haemostasis in Sydney, Australia.
When blood clots lodge in our brain or heart there are potentially fatal consequences such as stroke or heart attack. Cells in our blood called platelets are necessary for clotting to occur and O'Shaughnessy's research team showed that cocoa inhibits platelet function.
O'Shaughnessy said, "Cocoa contains a substance called flavinoids, which are also present in red wine. Flavinoids can be preventive for coronary heart disease; however our research has uncovered another ingredient in cocoa which may be responsible for the platelet inhibition. This finding may well lead to important new therapies to prevent heart disease and stroke. But it may also mean that a nice hot cup of cocoa may also take on new importance for people in high risk categories."
