More than eight million Americans over the age of forty experience peripheral artery disease. PAD is a narrowing of arteries that reduces blood flow to the legs and causes discomfort in leg muscles while walking. A preliminary study from Northwestern University’s Feinberg School of Medicine suggests some relief from that painful walking. Researchers found drinking flavanol-rich cocoa three times a day for six months enabled PAD patients to walk one hundred forty feet farther in a six-minute walking test than PAD patients not drinking cocoa. Those drinking cocoa also had improved blood flow and muscle function in their legs. Again, this is a preliminary study, but results appear in the American Heart Association’s journal Circulation Research.
