I going to qualify my comments that they reflect only the current 
information I've come across, good or bad.  I find the evidence 
compelling that cocoa has many health benefits and that it is closely 
related to a common tree found in Africa and used extensively there, 
that while some animals find the product unhealthy, man processes it's 
ingredients easily, as if well adapted to it.

But lets say I'm wrong, what then?  I've found the following questions 
valuable.

If I'm wrong on (issue X), what's the worst that can happen?
If I'm right on (issue X), what's the best that can happen?

At this point for me, the best that can happen far outweighs the worst 
that can happen.
