Phosphorus\u2019s Functional Role<\/h1>\r\nPhosphorus is present in our bodies as part of a chemical group called a phosphate group. These phosphate groups are essential as a structural component of cell membranes (as phospholipids), DNA and RNA, energy production (ATP), and regulation of acid-base homeostasis. Phosphorus however is mostly associated with calcium as a part of the mineral structure of bones and teeth. \u00a0Blood phosphorus levels are not controlled as strictly as calcium so the PTH stimulates renal excretion of phosphate so that it does not accumulate to toxic levels.\r\n

Dietary Reference Intakes for Phosphorus<\/h1>\r\nIn comparison to calcium, most Canadians are not at risk for having a phosphate deficiency. Phosphate is present in many foods popular in the Canadian diet including meat, fish, dairy products, processed foods, and beverages. Phosphate is added to many foods because it acts as an emulsifying agent, prevents clumping, improves texture and taste, and extends shelf-life. The average intake of phosphorus in adults ranges between 1,000 and 1,500 milligrams per day, well above the RDA of 700 milligrams per day. The UL set for phosphorous is 4,000 milligrams per day for adults and 3,000 milligrams per day for people over age seventy.\r\n\r\nTable 8.3 Dietary Reference Intakes for Phosphorus\r\n
