Most Americans dont have much room in their diets for a completely nutrient-void beverage. Corn flour has been important in Mesoamerican cuisine since ancient times and remains a staple in the Americas. For this reason, today the energy content of food is instead obtained indirectly, by using chemical analysis to determine the amount of each digestible dietary component (such as protein, carbohydrates, and fats), and adding the respective food energy contents, previously obtained by measurement of metabolic heat released by the body. This was the definition used at the time within the existing system of units. Many governments require food manufacturers to label the energy content of their products, to help consumers control their energy intake.
