Phosphorus in diet

Alternative names:

diet and phosphorus

Food sources:

The main food sources are the protein food groups of meat and milk. 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. However, the phosphorus in whole-grain products is in the form of phytin, which combines with calcium and forms a salt that is not absorbed and is unavailable for use by the body.

Fruits and vegetables contain only small amounts of phosphorus.

The intake of phosphorus beyond recommended amounts can cause phosphorus to combine with calcium and prevent the calcium's use by the body.
