If you have high blood pressure, a daily bar-sized serving of flavonol-rich dark chocolate might lower your blood pressure and improve insulin resistance, researchers report in Hypertension: Journal of the American Heart Association.

"Previous studies suggest flavonoid-rich foods, including fruits, vegetables, tea, red wine and chocolate, might offer cardiovascular benefits, but this is one of the first clinical trials to look specifically at dark chocolate's effect on lowering blood pressure among people with hypertension," said study author Jeffrey B. Blumberg, Ph.D.

Flavonoids are natural antioxidants found in many foods from plants.

"This study is not about eating more chocolate," Blumberg cautioned.
