Chocolate đen có tốt cho tim mạch không?

-----

Studies continue to show that cocoa flavanols can lower blood pressure (huyết áp) and arterial (động mạch) stiffness just like the best blood pressure medications. However, scientists have had some concern that consuming cocoa when your blood pressure is normal or low could lower it even further. Now, a new study finds there’s nothing to worry about! Researchers in Australia say cocoa only lowers blood pressure when it’s abnormally high (cao bất thường).

The new study notes that previous experiments (thí nghiệm trước đây) have only looked at cocoa’s beneficial impact on the heart under tightly controlled conditions. This has made it unclear as to whether cocoa also lowers blood pressure in already healthy people. For people who love chocolate, this doesn’t mean you should run out to the store and buy a case of Hershey bars. Chocolate that contains higher levels of cocoa will be the most beneficial — but don’t forget that chocolate treats can also contain high levels of sugar and fat. Any thoughts of using cocoa for lowering blood pressure should be discussed with your doctor first.
