Cocoa Increases Nitric Oxide, Fights Macular Degeneration, and Reduces Blood Pressure

The consumption of flavanol-rich cocoa increases nitric oxide production, which improves endothelial function. The antioxidants in cocoa may prevent and reduce age-related macular degeneration (ARMD). Cocoa has also been demonstrated to reduce blood pressure. The best cocoa to use for these health purpose is cocoa powder without sugar.
