A Chocolate Study Worth Its Cocoa
A small study that appeared in the Journal of the American Medical Association this month found that eating just 6.3 grams of dark chocolate a day can reduce blood pressure (BP).1 Previous studies found a BP-lowering benefit with eating dark chocolate, but the amounts tested were often in the 100 gram range. This is the first study to document benefit with such a small amount.
Participants of the study were 44 adults with either upper-range prehypertension or stage 1 hypertension (see chart) . After 18 weeks, those who were consuming 6.3 grams (about 1 square inch) of dark chocolate daily reduced their systolic BP by an average of 2.9 mm Hg, their diastolic by 1.9 mm Hg. (This is about the reduction seen in participants of the HOPE Study who were on an ACE inhibitor.)
The chart is extracted from the NIHs brochure: The Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure.
If youd like to give this a try, you may want to eat the small amount of chocolate every day. In this study, there was no BP-lowering effect for the first 6 weeks. A gradually increasing effect became apparent after that, with the strongest effect at the end of the study (18 weeks).
