One study measured the Minimum Erythema Dose (MED) - this is a measure of how much exposure would start to negatively affect the skin. A high MED is good because it means you need to be exposed to more UV rays to get hurt.
MED was significantly increased for the group of study participants who consumed cocoa rich in flavonols for several weeks. For the group that did not consume or consumed chocolate with lower flavonols, there was no change.

A recent study done at Harvard looked at 24 past studies on the effects of chocolate with more than 1,000 participants and collectively concluded that dark chocolate with 50 to 70% cocoa content had the effect of lowering blood pressure in all participants.
