The caffeine content of chocolate has been the subject of much debate -- and conflicting research from the scientific community. Some data sugests that there is caffeine content in the cocoa bean, though the International Cocoa Organization states that the caffeine content is very low. Other data suggests that there is no caffeine in cocoa, and that any caffeine present has been added by manufacturers. It's also interesting to note that some data suggests that the caffeine only resides in the fiber and husk that surround the cocoa bean. In that case, if the beans are properly cleaned, there should be virtually NO caffeine in the resulting chocolate product. - http://www.thefivereasons.com/
