There is growing scientific evidence that antioxidants and other beneficial substances in dark chocolate may reduce risk factors for heart disease and other physical conditions. Studies also suggest that chocolate may ease emotional stress. Until now, however, there was little evidence from research in humans on exactly how chocolate might have those stress-busting effects.

Cocoa Can Decrease Blood Pressure, Study Shows

The study populations were either healthy adults with normal blood pressure or patients with prehypertension or stage 1 hypertension. Treatment duration ranged from two to 18 weeks.

Across all trials, consumption of cocoa products was associated with a mean 4.5 mm Hg decrease in systolic pressure and a mean 2.5 mm Hg decrease in diastolic pressure, the researchers reported in the American Journal of Hypertension (2010;23:97-103).
