    So when you burn food it loses all nutrition value and transfers to heat energy but I wonder about the smoke that is produced when it's burnt. Can that smoke contain any caloric value? As the energy is released wouldn't it need to go somewhere? Is there any nutritional value in the smoke from burnt food?

    If you burned it completely and got the maximum heat energy from the food the products would be carbon dioxide, water and oxides of the other trace elements present. The fact you have soot or smoke (or any solid matter) left over tells you that you have not burned the food completely. Burning the solid residue would produce more heat (but a much smaller amount than present in the original food).

    The energy released does go somewhere - into the surroundings where it heats up the air. This is why fires are hot
