One way that I know that cacao is bad is how my body reacts to it. Since I've been eating a very clean diet for many years now, I can trust my body's reactions. However, there is more objective information to be had for those who wish to find it. For example, I just did a cursory search and found the comments below by Frederic Patenaude. Cacao is #3 on his list of "the unhealthiest foods that people think are healthy". The info that you'll find on line is mostly focussed on the positive aspects of chocolate because so many people are selling it, but the truth can be found if you look hard enough. I think Doug Graham has written about the poisonous effects of cacao, and I'd be surprised if it hasn't been written about truthfully in Living Nutrition magazine, as well.

"Coffee, Black Chocolate and Cacao — First premise: coffee, chocolate and cacao (raw or cooked) are stimulants. They contain certain substances (caffeine and theobromine) that disturb the nervous system. If a person is eating a more natural diet, these poisons have an even more disturbing effect on the system. For a raw- foodist, one cup of coffee has the effect of maybe four cups for someone eating a standard American diet. Personally, half a cup of coffee taken in the morning will disturb my sleep at night, while my dad can drink a cup in the evening and still fall asleep. However, as Shelton wrote: “toleration to poisons is merely a slow method of dying. Instead of seeing in the phenomena of toleration something to be sought after, it is something to seek to avoid the necessity for.” A detoxified person is much like a child: she will strongly react to the smallest dose of any intoxicant.
So there is no room for compromise with caffeinated drinks and cacao products, which include: coffee, hot chocolate, black chocolate, raw cacao beans, black tea, green tea, maté tea, etc."
