Cholesterol is mostly found in animal products. As a plant-based product, cocoa butter contains only a small amount of cholesterol. As a result, dark chocolate contains a very small amount of cholesterol (less than 5 mg/100 g). As milk chocolate and white chocolate contain milk powder they contain a bit more cholesterol, however those quantities remain small. Milk and white chocolate contain around 15 and 20 mg of cholesterol per 100 g respectively. As a comparison, the level of cholesterol in eggs is slightly less than 380 mg per 100 g(1).
Additionally, it is becoming increasingly accepted that dietary cholesterol has minimal influence on blood cholesterol². For instance, in the new American dietary guidelines, cholesterol is no longer considered a nutrient of concern(3).
