Dark Chocolate Good for the Heart
Willie Wonka, the chocolate entrepreneur, is on the right track. Chocolate, at least dark, flavanol-rich chocolate, is good for you, say researchers here.
A daily 3.5 ounce bar of dark chocolate was associated with an average 11.9 mm Hg drop in systolic blood pressure and an 8.5 mm Hg decline in diastolic pressure (P<0.0001) in a study that compared the potential health benefits of dark chocolate to white chocolate, reported Jeffrey B. Blumberg, Ph.D., of the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts.
And that's only half the story, dark chocolate also decreased total cholesterol (P<0.05), and serum LDL cholesterol (P<0.05) but not triglycerides or HDL. It also improved flow-mediated dilation (FMD), and ameliorated insulin sensitivity in hypertensives.
