From the post linked to above:

"And a diet heavy in chocolate is a diet heavy in sugar, calories, and fat."

Except when it's not. I would love to see some studies focusing on the benefits of non-candy cocoa in a healthy, sugar free diet.

I enjoy a lot of plain, unsweetened, cocoa powder - in my coffee, in spiced teas, as mole sauces and rubs and mixed with coconut cream in frozen desserts (with no added sugar or artificial sweeteners), and I believe that it is a good source of fibre, and potassium among other things.
The main trouble I see with chocolate is that everyone assumes you can only enjoy it as a sweetened candy bar. The deliciousness is still there if you can ween yourself off the sugar.
