Is coffee a carbohydrate lipid or protein?

Coffee itself is primarily composed of water and contains minimal amounts of carbohydrates, lipids, and proteins. The main components in coffee are caffeine, antioxidants, and various other compounds that contribute to its flavor and aroma. While brewed coffee has negligible macronutrients, coffee beans do contain small amounts of carbohydrates and proteins. However, when consumed as a beverage, coffee is not classified as a significant source of any of these macronutrients.
