Colleagues and I just published research in the American Journal of Clinical Nutrition indicating that both solid dark chocolate and liquid cocoa favorably influence blood pressure and blood flow in overweight adults.
This is just the latest in a litany of findings that indicate if you choose dark chocolate, a food you love will love you, and your blood vessels, back.
There are more questions to answer, but I feel we know enough to treat dark chocolate like red wine at this point: you might actually add it to your diet for cardiovascular benefit. But as with wine, dose is an important consideration. Too much chocolate will show up at your waistline, and cancel out any benefits.
An ounce or two of dark chocolate, at least 60% cocoa, daily is apt to be beneficial if you make room for these calories so they don't cause weight gain. The same is true of a daily mug of hot cocoa, provided the sugar content is kept low.
Note that in most studies of dark chocolate, milk chocolate is the placebo. So stay on the dark side to make the bright health benefits of chocolate, along with its pleasures, a routine part of your diet.
