<snip>Despite the enthusiasm, flavanols are missing from much of the chocolate on store shelves today. Flavanols make chocolate and cocoa taste bitter, and confectioners have spent years trying to perfect ways to remove the pungent flavor.
"Most chocolate, in fact, isn't flavanol-rich," said Norm Hollenberg, a radiology professor and flavanol expert at Harvard Medical School. "But all chocolate is rich in fat and calories. Chocolate is a delight. It can and should be part of a prudent diet. That means you limit what you take."
Flavanols are found in other foods, such as red wine, grapes, apples and green tea, although cocoa beans are a particularly rich source.<snip>
<snip>Researchers are excited by the potential of flavanols to ward off vascular disease, which can cause heart attacks, strokes, diabetes, dementia and hypertension. Vascular diseases are linked to the artery's inability to make a simple but fundamental chemical called nitric oxide. Flavanols appear to reverse that problem.
"The pharmaceutical industry has spent tens, probably hundreds of millions of dollars in search of a chemical that would reverse that abnormality," Hollenberg said. "And God gave us flavanol-rich cocoa, which does that. So the excitement is real."
