Function The main function of phosphorus is in the formation of the 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. Phosphorus works with the B vitamins in their functions in the body. It also assists in the contraction of muscles, in the functioning of kidneys, in maintaining the regularity of the heartbeat, and in nerve conduction.
Phosphate molecules are also important in bone structure and for the modulation of plasma and bone calcium. The compound calcium "hydroxyapetite" is a complex of calcium, phosphate, and hydroxyl groups; and is often used as a supplement for bone replacement. The more accurate breakdown is:- Birth-3 years: 300-800mg
- 4-10 years: 800mg
- Adults, men and women: 800-1200mg
- Pregnancy/lactating women: 1200mg.
. Most diets in the U.S. have adequate amounts of phosphorus. Phosphorus is a mineral that makes up 1% of total body weight. It is present in every cell of the body, but 85% of the body's phosphorus is found in the bones and teeth.
Cells contains phospholipids, phosphorylated proteins, and the DNA backbone is highly saturated with phosphate molecules. Excessively high levels of phosphorus in the blood, although rare, can combine with calcium and deposit in soft tissues like muscle. These high levels of phosphorus in blood only occur in people with severe kidney disease or severe dysfunction of their calcium regulation. The main food sources are the protein food groups of meat and milk (also lentils, seeds, beans, nuts, chocolate, peanut butter, bran.) A meal plan that provides adequate amounts of calcium and protein also provides an adequate amount of phosphorus. Whole-grain breads and cereals contain more phosphorus than refined cereals and breads made from refined flour. Fruits and vegetables contain only small amounts of phosphorus. Phosphorus is often added to multi-mineral products as well as bone supplementation products. |
