The following table shows the calories per gram for a variety of foods. The data makes it clear that although the 4-4-9 method of calculating calories is an approved AOAC Method - it is also only a very crude approximation of actual values. This is why NutriBase uses the conversion factors provided by the USDA to calculate the "percent calories from" and "calories from" values for Protein, Carbohydrates, and Fat.
