In their book, Heart 411, Drs. Gillinov and Nissen say:
Although dark chocolate is widely believed to have “magical” health properties, we don’t really have evidence proving that a daily serving of dark chocolate improves long-term health. Experimental evidence does suggest that antioxidants found in cocoa can modestly lower blood pressure. And dark chocolate does tend to have a higher cocoa content than milk chocolate. But these antioxidants have a bitter taste, and manufacturers therefore often remove them when processing the cocoa. Today, we have only theoretical reasons to believe that dark chocolate might be better. Choose your chocolate based upon your taste (we do prefer the taste of dark chocolate!) and limit your intake to prevent weight gain.
