Why do we need food?

Simply put, food fuels the human body. Without it, the body cannot grow or perform at its best, the organs stop working properly, and the body eventually dies. Food supplies nutrients, which are used by every cell in the body as building materials and fuel.

The human body requires a wide range of nutrients to remain healthy, including vitamins, minerals, fat, protein, fiber and carbohydrates. Carbohydrates or sugars burn fast for quick energy, while protein molecules are used by cells for complex processes. The body also needs water, a substance that is needed for every process that the body performs.
