I believe they no longer use the burning method [1] for measuring food energy, since it overestimates energy of high-fiber foods (fiber doesn't get burned when in the body, but it does get burned during measurement.) I believe nowadays they estimate the caloric content based on the fat, carbohydrate, and protein content of the food.
