Phosphorus is an important constituent of human bones, meaning that it would be impossible to one function normally without an adequate amount of this mineral in the body. Phosphorus is the second most abundant element in the human body (second to calcium). [, Palmer SC, Hayen A, Macaskill P, et al. Phosphorus, an essential mineral, is naturally present in many foods and available as a dietary supplement. Treatment typically consists of vitamin D and phosphorus supplementation from diagnosis until growth is complete [41]. Serum levels of phosphorus, parathyroid hormone, and calcium and risks of death and cardiovascular disease in individuals with chronic kidney disease: a systematic review and meta-analysis. 2.1.3 The revised phosphorus regulation: direct phosphorus ceilings at farm level As a consequence of the changes in regulation, according to the latest political agreement on Food and Agriculture (section 1.2), a revised regulation addressing phosphorus is introduced in 2017. Phosphorus is a component of bones, teeth, DNA, and RNA [1]. [, Calvo MS, Moshfegh AJ, Tucker KL. In: Uribarri J, Calvo MS, eds. [, Menon MC, Ix JH. As a result, there is no official tolerable upper intake level (UL) set for phosphorus.

Dietary Reference Intakes for Vitamin A, Vitamin K, Arsenic, Boron, Chromium, Copper, Iodine, Iron, Manganese, Molybdenum, Nickel, Silicon, Vanadium, and Zinc. Ann N Y Acad Sci 2013;1301:21-6. In 7,895 adults (mean age 47 years, 52% Caucasian), participants with moderately reduced kidney function had significantly higher serum phosphate levels (4.12 ml/dL) than those with normal kidney function (3.74 mg/dL) [47]. In the form of phospholipids, phosphorus is also a component of cell membrane structure and of the body’s key energy source, ATP. Trautvetter U, Jahreis G, Kiehntopf M, Glei M. Consequences of a high phosphorus intake on mineral metabolism and bone remodeling in dependence of calcium intake in healthy subjects - a randomized placebo-controlled human intervention study. Kidney Int 2016;89:176-84. The connection between dietary phosphorus, cardiovascular disease, and mortality: where we stand and what we need to know. Phosphorus and calcium are interrelated because hormones, such as vitamin D and parathyroid hormone (PTH), regulate the metabolism of both minerals. Causes of malnutrition that can lead to refeeding syndrome include chronic diseases (e.g., cancer, chronic obstructive pulmonary disease, or cirrhosis), very low birthweight, cachexia, low body weight, anorexia nervosa, excessive alcohol intake, and chewing or swallowing problems.

[, Casais MN, Rosa-Diez G, Perez S, et al. Food Labeling: Revision of the Nutrition and Supplement Facts Labels. In humans, phosphorus makes up about 1 to 1.4% of fat-free mass. In studies of infants receiving different calcium intakes 21), 22), 23), 24), phosphorus retention did not differ even with high amounts of dietary calcium (calcium:phosphorus [Ca:P] molar ratios of 0:6, 1:1, or 1.4:1). Phosphate ions play very important roles in the body as Phosphate ions are found in the ATP, AMP, 2,3 DPG and proteins. [. [, Parli SE, Ruf KM, Magnuson B.

The body needs phosphorus to build and repair bones and teeth, help nerves function, and make muscles contract. The Percentage of Dietary Phosphorus Excreted in the Urine Varies by Dietary Pattern in a Randomized Feeding Study in Adults. The effects of hypophosphatemia can include anorexia, anemia, proximal muscle weakness, skeletal effects (bone pain, rickets, and osteomalacia), increased infection risk, paresthesias, ataxia, and confusion [1]. Phosphorus deficiency in preterm infants is one of the main causes, along with calcium deficiency, of osteopenia of prematurity (impaired bone mineralization) [36]. It is also needed for the body to make protein for the growth, maintenance, and repair of cells and tissues. Asia Pac J Clin Nutr 2011;20:411-7. Most Americans consume more than the recommended amounts of phosphorus. USA.gov. Additional studies are needed on the link between phosphate concentrations and both CKD risk and morbidity in patients with CKD as well as the impact of dietary phosphorus restriction in patients with this disease. The adult human body contains about 1000 g of calcium and 700 g of phosphorus. Prophylactic administration of phosphorus and thiamin in patients at risk of refeeding syndrome can prevent this condition [43]. [, Pavone V, Testa G, Gioitta Iachino S, et al. It plays an important role in how the body uses carbohydrates and fats. eCollection 2020 Jul.

It is thought that excess amounts of phosphorus intake for long periods are a strong factor in bone impairment and ageing. 10th ed. [, Liu Z, Su G, Guo X, et al. FDA does not require food labels to list phosphorus content unless phosphorus has been added to the food. In: Gutierrez OM, Kalantar-Zadeh K, Mehrotra R, eds. However, the group notes that clinical trial data showing that treatments that lower serum phosphate levels improve patient-centered outcomes are lacking, and it acknowledges that this recommendation is weak.

NCI CPTC Antibody Characterization Program. High phosphorus intakes might be signs of diets that are unhealthy in other ways, for example [65]. KDIGO 2017 Clinical Practice Guideline Update for the Diagnosis, Evaluation, Prevention, and Treatment of Chronic Kidney Disease-Mineral and Bone Disorder (CKD-MBD),. The table below shows just some of the foods that contain calcium, vitamin D and phosphorus. PHOSPHOROUS METABOLISM 1. Arch Intern Med 2007;167:879-85. Phosphorus in supplements is usually in the form of phosphate salts (e.g., dipotassium phosphate or disodium phosphate) or phospholipids (e.g., phosphatidylcholine or phosphatidylserine). In addition, phosphorus plays key roles in regulation of gene transcription, activation of enzymes, maintenance of normal pH in extracellular fluid, and intracellular energy storage. The prevalence of phosphorus-containing food additives in top-selling foods in grocery stores. Serum Pi level is maintained within a narrow range through a complex interplay between intestinal absorption, exchange with intracellular and bone storage pools, and renal tubular reabsorption. The crucial regulated step in Pi homeostasis is the transport of Pi across the renal proximal tubule. Phosphate is one of the body's electrolytes , which are minerals that carry an electric charge when dissolved in body fluids such as blood, but the majority of phosphate in the body is uncharged. For infants from birth to 12 months, the FNB established an AI for phosphorus that is equivalent to the mean intake of phosphorus in healthy, breastfed infants. Scientific Opinion on Dietary Reference Values for phosphorus. In spite of the evidence supporting a link between increased phosphate levels and CVD risk, the literature offers no evidence on whether restricting phosphorus consumption can prevent CVD in healthy adults [64]. Adv Nutr 2014;5:104-13. Impact of phosphorus-based food additives on bone and mineral metabolism. The human response to acute enteral and parenteral phosphate loads.  |  J Endocr Soc 2017;1:407-14. The combination of high phosphorus intakes with low calcium intakes increases serum PTH levels, but evidence is mixed on whether the increased hormone levels decrease bone mineral density [2,4-6]. Phosphorous Metabolism Gandham. Epub 2020 Oct 9. In the United States, dairy products contribute about 20% of total phosphorus intakes, and bakery products (e.g., breads, tortillas, and sweet bakery products) contribute 10% [13]. *DV = Daily Value. Boca Raton, Florida: CRC Press; 2018:221-33. Regulation of calcium, phosphate, and magnesium occurs in different parts of the nephron and involves a number of different channels, transporters, and pathways. [, Ito S, Ishida H, Uenishi K, et al. The skeletal structure and vital organs — including the brain, heart, kidneys and liver, for example — all rely on it to keep the body functioning properly. [. Increased phosphorus retention often leads to CKD mineral and bone disorder. In most cases, hypophosphatemia is caused by medical conditions, such as hyperparathyroidism, kidney tubule defects, and diabetic ketoacidosis [35]. 2000 Oct 25;168(1-2):41-51. doi: 10.1016/s0303-7207(00)00310-5.
