The primary function of food in the body is the energetic function
Explanation:
The body needs energy to develop its differents functions, such as movement, breathing, thinking, etc. Each one of those functions requires a certain amount of energy to be developed, and when food enters the body, the digestive system is in charge of digestion, which is the process through which food is turned into proteins and other substances that the body absorbs and turns into energy. The energy that is not spent turns into fat and is stored in that way.
