Health Benefits Without The Fat & Sugar. The average 40 gram bar of dark chocolate contains 250 calories and 14 grams of fat! If the chocolate bar uses Dutch processs cocoa, some of the polyphenols will be destroyed. NuNaturals Cocoa Extract contains 15% of the polyphenols and 10% theobromines in Cocoa. Ten milliliters of our Cocoa Extract would contain the same amount of polyphenols and theobromines in a chocolate bar at about the same cost, but without the fat and calories! But how does it taste? Delicious! We have added a touch of our non-bitter NuStevia extract to complement the taste of the Cocoa extract.
