Caloric polynomial

A caloric polynomial is like a math equation. It combines different numbers and letters in order to represent the amount of energy in food. The numbers used in the equation are calories, which are a measure of how much energy is in something. The letters used in the equation stand for different kinds of nutrients like protein, carbohydrates, and fats. By combining all of this information together, a caloric polynomial tells us how much energy is in a certain food.
