Chocolate does cause acne in some people. Many will tell you this is a myth. Science hasn't been able to figure out just how chocolate might cause this. This may be because it doesn't affect all people in the same way. But, I can speak from personal experience. I've stayed away from chocolate for two years (and only chocolate), and found that only when I break this restriction (for the specific purpose of testing this theory) do I have acne break-outs. Specifically, it is not merely cocoa, but bars of chocolate (both dark and milk varieties) which cause the problem for me. Perhaps it has something to do with the oils in that kind of chocolate. I don't know. All I know is that eating such chocolate is a sure path to acne for me. Hope this helps. Tim
