This is baffling me... different foods are made up of different substances and are all digested differently, So how do they work out the number on the label?? I have tried Google and it confused me even more, Theories & facts welcome please!

    The Calorie you see on a food package is actually a kilocalorie, or 1,000 calories. A Calorie (kcal) is the amount of energy needed to raise the temperature of 1 kilogram of water 1 degree Celsius. ... The food was completely burned and the resulting rise in water temperature was measured.

    "Old method" but technically correct
