It is nearly as dangerous to base life's decisions on individual scientific studies as it is on Bible verses taken out of context. Nonetheless, I enjoy reporting encourging news, and this morning's is about chocolate. This Scientific American article reports on a study of the cocoa consumption (in any form) of 470 elderly Dutch men, which found that those who ate the most cocoa were half as likely to die of cardiovascular or any other disease as those who ate the least. They haven't identified the protective mechanism yet; maybe it was the antioxidants, maybe the men were just happier. :)
Still, there's no need to go overboard on the Ghirardelli. The average daily cocoa consumption of the highest group was "more than four grams." Four grams is not a lot of cocoa, even in its pure form.
