There are mainly the following substances that generate heat in human body: sugar, lipid, protein and alcohol.

Among them, the heat generated by alcohol cannot be directly used by the human body.

The heating ratio of carbohydrate lipid protein is about 1: 3: 1.

The heat production of 1g glucose is 16.4KJ.

1 sucrose is converted into 1 glucose and 1 fructose.

There is a list of ingredients on the outer packaging of cola, which has its material content and total calories. It can be calculated that the main energy-supplying substance is carbohydrate, that is, sugar.

Thank you.
