What energy does food produce?

Food produces mechanical energy because mechanical energy is to do something and food gives you the energy to do something.

No.

Food is the energy from sunlight stored as chemical energy. When you eat food yo convert it into a different sort of chemical store (again chemical energy) before you can use it as mechanical energy. Even then most of the food is used keeping you warm and in this case the food is converted into heat rather than mechanical energy.
