UPDATE: I continue to admire the people running ChocoNat and believe they have the highest quality chocolate products of anyone in network marketing. For other reasons, I moved on from this business and into a healthy meal program that can appeal to the entire population with meals that are convenient, affordable, and loaded with nutrition.

There are many scientific studies showing the health value of dark chocolate. ChocoNat has not yet funded any studies of its own chocolate, but because it uses raw cacao and a low-glycemic sweetener (raw cane juice), I believe it will meet or exceed the results seen from the cooked chocolate no doubt used in these studies.
Please use this information for educational purposes only. ChocoNat is healthy food, and as such may help to improve your health. But it is not medicine and is not in the business of diagnosing, treating, preventing, or curing disease.
Cocoa or dark chocolate may positively affect the circulatory system. Other possible effects under basic research include anticancer, brain stimulator, cough preventor and antidiarrhoeal activities.
Limited amounts of dark chocolate appear to help prevent heart disease. The oxidation of LDL cholesterol is considered a major factor in the promotion of coronary disease. When this waxy substance oxidizes, it tends to stick to artery walls, increasing the risk of a heart attack or stroke. Research has shown the polyphenols in chocolate inhibit oxidation of LDL cholesterol.
Research has shown that it will boost cognitive abilities. Further, dark chocolate and cocoa butter have been linked with multiple positive effects. Scientific evidence has suggested dark chocolate can help reduce the risk of cardiovascular problems  and also reduce blood pressure in both overweight and normal adults. Finally, studies have shown dark chocolate can lower cholesterol levels in adults.
For 3 weeks, one group in a study got one dark chocolate bar a day. The other group got none. At the end: "All subjects underwent high-tech evaluation of how well the blood vessels dilate and relax -- an indictor of healthy blood vessel function. Blood vessel stiffness indicates diseased vessels and possible atherosclerosis. Those who got the full-flavonoid chocolate did significantly better. Why? Blood tests showed that high levels of epicatechin were coursing through their arteries." Reference.
