Energy

In nutritional analysis, this is theoretically derived from the known value of energy contributed from the amount of fat, sugar, carbohydrate, protein and fibre in a product. Expressed as Kilocalories or calories and kilojoules. The more fat, sugar, carbohydrate, protein or fibre the more the energy value will be. As it is calculated a discrepancy in any of the contributing elements can skew the energy value.
