Calories are units of measurement for energy content in food. They represent the amount of energy released when food is processed and metabolized by the body. In simpler terms, calories are a way to gauge how much heat or energy a particular food can provide when consumed. Caloric content is often used to indicate the amount of energy a person derives from their diet. It is important to note that calories themselves do not measure the nutritional value of food, as different foods can have the same calorie content but vary greatly in terms of nutrients.
