Aim for at least 70%, though it still does have a lot of sugar. The higher the percentage the better, because obviously the cocoa content is higher, but the chocolate will also have less sugar.
Chocolate is a great superfood. I've been skipping the chocolate bars altogether and adding raw cacao powder to my smoothies- that way you are only sweetening it with fruit instead of sugar.

the studies on dark chocolate are often misinterpreted or bent a little attract more people to health websites. For instance, people always use the Harvard study on dark chocolate which says one square a day may lower blood pressure. People go to far in assuming that eating a whole bar will better the effects...
