Get ready for the onslaught of ads promoting chocolate as a wonder food for the heart:
A carefully conducted German trial has shown that eating a small square of dark chocolate a day can reduce blood pressure by a few points in healthy people with above-normal blood pressure.
The finding, published in the Journal of the American Medical Association, joins a handful of others showing an effect of dark chocolate on blood pressure. Only dark chocolate will do, since it is rich in the antioxidants known as polyphenols. In the trial, volunteers ate a 6-gram chunk of dark chocolate (about one-fifth of an ounce) that delivered just 30 calories a day. (For comparison’s sake, a regular Hershey bar is 1.5 ounces.)
Dark chocolate won’t replace blood-pressure medicines. But having a small square a day may be a delicious way to help them along.
