Dark chocolate does contain saturated fat. Not all saturated fat is bad for you, and good fats are necessary when trying to lose weight. Dark chocolate contains three types of fat: oleic acid, stearic acid and palmitic acid. Oleic acid is a monounsaturated fat that lowers your cholesterol. Stearic acid, when metabolized, turns into oleic acid. Palmitic acid has been shown to raise cholesterol levels; however, when combined with oleic and stearic acid, the overall effects on cholesterol are irrelevant.
