All foods have a calorific value, which means the amount of energy you get from eating them. It is expressed as so many calories (actually these are kilocalories) per 100 grams of the particular food. You can find nutritional tables for different food types. Calories are related to joules by the mechanical equivalent of heat, which is 4.2 joules per calorie.
