I know, it sounds like contradiction in terms. Did you know that chocolate used to be really healthy? It was called food for the gods. Only when the Europeans got their hands on it and started dutching it and making it available for the masses it turned unhealthy because of all the sugar and other ingredience that were added.
For me personally it helps me stay off any kind of candy and as a welcome side effect I don't have any menstruation pains and cramps anymore.
