What does a calorie measure in food?
Correct!
A calorie is a unit of energy. In nutrition, the word calorie usually refers to a kilocalorie (kcal). It describes how much energy a food can provide to the body. One kilocalorie equals 4.184 kilojoules. The body uses this energy, among other things, for basic bodily functions and physical activity.
Nutrition labels usually use the kilocalorie, written as kcal.
