What are the 5 Functions of Food?

The five functions of food are:

Providing energy: Food provides the body with energy in the form of calories that are derived from carbohydrates, proteins, and fats. This energy is necessary for the body to perform its daily functions.

Building and repairing tissues: Food provides the raw materials needed to build and repair tissues in the body. Proteins are particularly important for this function as they are used to build muscle, skin, hair, nails, and other tissues.

Regulating body processes: Nutrients in food are involved in regulating various body processes, including metabolism, hormone production, and immune function.

Transporting substances: Food provides the necessary nutrients and substances that are transported through the blood to various parts of the body. For example, iron in food is used to transport oxygen to cells.

Providing protection: Certain nutrients in food, such as vitamins and minerals, can provide protection against diseases and illnesses. For example, vitamin C is important for the immune system, while calcium is necessary for strong bones.

In summary, the five functions of food are providing energy, building and repairing tissues, regulating body processes, transporting substances, and providing protection.
