Yep, the Mayans and Aztecs consumed cocoa regularly and referred to it as a 'food of the gods'! I'm not sure if they attributed any medicinal effects to it...but I tend to agree with you, the sugar, dairy and fats are probably the bigger problems with chocolate than the cocoa itself.
That's why I posted the original message to begin with...certainly didn't expect the response it got. Many people need to give things up in stages. Eliminating the dairy and Sugar is already a big improvement over the conventional alternative. I think in many cases it is more helpful to think of things in terms of healthier choices rather than extremes of good or bad. I know this approach greatly helped me move in a direction of healthier diet and lifestyle choices.
