It is the second most abundant mineral in the body. It is present in every cell of the body. 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 how the body uses carbohydrates and fats. It is also needed for the body to make protein for the growth, maintenance, and repair of cells and tissues. Phosphorus also helps the body make ATP, a molecule the body uses to store energy.CarbohydratesCarbohydrates are one of the main nutrients in our diet. They help provide energy for our body. There are three main types of carbohydrates found i...Read Article Now Book Mark Article ProteinProteins are the building blocks of life. Every cell in the human body contains protein. The basic structure of protein is a chain of amino acids. ...Read Article Now Book Mark Article Phosphorus works with the B vitamins. It also helps with the following: Kidney function Muscle contractions Normal heartbeat Nerve signaling Food Sources The main food sources are the protein food groups of meat and milk, as well as processed foods that contain sodium phosphate. A diet that includes the right amounts of calcium and protein will also provide enough phosphorus.Whole-grain breads and cereals contain more phosphorus than cereals and breads made from refined flour. However, the phosphorus is stored in a form that is not absorbed by humans.Fruits and vegetables contain only small amounts of phosphorus. Side Effects Phosphorus is so readily available in the food supply, so deficiency is rare.Excessively high levels of phosphorus in the blood, although rare, can combine with calcium to form deposits in soft tissues, such as muscle. High levels of phosphorus in blood only occur in people with severe kidney disease or severe dysfunction of their calcium regulation. Recommendations Dosages for phosphorus, as well as other nutrients, are provided in the Dietary Reference Intakes (DRIs) developed by the Food and Nutrition Board at the National Academies of Sciences, Engineering, and Medicine. DRI is a term for a set of reference intakes that are used to plan and assess the nutrient intakes of healthy people. These values, which vary by age and sex, include:Recommended Dietary Allowance (RDA): The average daily level of intake that is enough to meet the nutrient needs of nearly all (97% to 98%) healthy people. An RDA is an intake level based on scientific research evidence. Adequate Intake (AI): This level is established when there is not enough scientific research evidence to develop an RDA. It is set at a level that is thought to ensure enough nutrition.Dietary Reference Intakes of phosphorus:0 to 6 months: 100 milligrams per day (mg/day)* 7 to 12 months: 275 mg/day* 1 to 3 years: 460 mg/day 4 to 8 years: 500 mg/day 9 to 18 years: 1,250 mg Adults: 700 mg/day Pregnant or lactating women: Younger than 18: 1,250 mg/day Older than 18: 700 mg/day *AI or Adequate IntakeOpen ReferencesReferencesMason JB, Booth SL.
