Phosphorus in diet - Overview

Alternative Names

Diet - phosphorus

Definition of Phosphorus in diet:

Phosphorus is a mineral that makes up 1% of a person's total body weight. It is present in every cell of the body, but most of the phosphorus in the body is found in the bones and teeth.

Function:

The main function of phosphorus is in the formation of bones and teeth. It plays an important role in the body's utilization of carbohydrates and fats and in the synthesis of protein for the growth, maintenance, and repair of cells and tissues. It is also crucial for the production of ATP, a molecule the body uses to store energy.

Phosphorus works with the B vitamins. It also assists in the contraction of muscles, in the functioning of kidneys, in maintaining the regularity of the heartbeat, and in nerve conduction.
