An average person contains a little less than 1 kg of phosphorus, about three quarters of which is present in bones and teeth in the form of apatite. Phosphorus is essential part of all body cells. Phosphorus helps

  • releasing energy
  • regulating protein activity

Deficiency in phosphorus unlikely because it is added in many commercial foods and it is a key element in all plant and animal cells.

High intake of phosporus without adequate calcium may cause demineralization of bone. The demineralization of bone is one factor in osteoporosis. So high phosporus low calcium diet may lead to osteoporosis. Luckily, most of the food high in phosphorus are also high in calcium.
