Eventually it is used for energy or stored in cells for later.

How does the body get energy from food?

Every organ of the body needs energy to function. Quite predictably, this energy comes from the food we eat.

What are the sources of energy in the human body?

Do all foods supply the same amount of energy?

All foods supply calories for energy, but not all calories are equal.
