HHS Adequate Intake (AI): Intake at this level is assumed to ensure nutritional adequacy; established when evidence is insufficient to develop an RDA. The prevalence of phosphorus-containing food additives in top-selling foods in grocery stores. The absorption rate for the phosphorus naturally contained in food is 40%–70%; phosphorus from animal sources has a higher absorption rate than that from plants [15,16]. Chronic kidney disease
For example, an analysis of 14,675 participants (55% women) without atrial fibrillation found, based on almost 20 years of follow-up, that each 1 mg/dL increase in serum phosphate was associated with a 13% higher risk of atrial fibrillation . J Endocr Soc 2017;1:407-14. It`s mostly eliminated through the urine and less through the stool. Am J Clin Nutr 2013;98:6-15. High dietary phosphorus intake is associated with all-cause mortality: results from NHANES III. It is noteworthy that, excessive consumption accelerates the aging processes  . 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. [, Lopez FL, Agarwal SK, Grams ME, et al. Karpen HE. Rajeev 2. Public health impact of dietary phosphorus excess on bone and cardiovascular health in the general population. The kidneys, bones, and intestines regulate phosphorus homeostasis, which requires maintenance of urinary losses at equivalent levels to net phosphorus absorption and ensuring that equal amounts of phosphorus are deposited and resorbed from bone [1,7,8]. McClure ST, Rebholz CM, Phillips KM, Champagne CM, Selvin E, Appel LJ. 2020 May 27;7(14):2000439. doi: 10.1002/advs.202000439.

In its clinical practice guideline for CKD mineral and bone disorder, the "Kidney Disease: Improving Global Outcomes" guidelines development group recommends that patients with stage 3–5 (more severe) CKD limit dietary phosphorus intake either alone or in combination with other treatments to reduce phosphate levels . Of this amount, 85% is in bones and teeth, and the other 15% is distributed throughout the blood and soft tissues . The following groups are most likely to have inadequate phosphorus status. Dietary Reference Intakes for Vitamin A, Vitamin K, Arsenic, Boron, Chromium, Copper, Iodine, Iron, Manganese, Molybdenum, Nickel, Silicon, Vanadium, and Zinc. J Physiol 2014;592:3985-95.

Am J Clin Nutr 2007;85:604S-7S. 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 . The ULs for phosphorus from food and supplements for healthy individuals are therefore based on intakes associated with normal serum phosphate concentrations . Phosphorus regulates pH balance by soaking up or freeing particular molecules that can tip the scales toward acidity or alkalinity. When it comes to phosphorus deficiency, the parathyroid glands secrete the parathyroid hormone, which releases calcium from the bones, while our mineral is released. Many different types of foods contain phosphorus, mainly in the form of phosphates and phosphate esters . The table below shows just some of the foods that contain calcium, vitamin D and phosphorus. Available data show that healthy individuals can tolerate intakes up to at least 3000 mg per day without severe health consequences. [. eCollection 2020 Jul. [, Parli SE, Ruf KM, Magnuson B.

As kidney function declines, phosphate excretion becomes less efficient and serum phosphate concentration rises. 2005;25:197-214. doi: 10.1146/annurev.nutr.25.050304.092642. Phosphorus and calcium are interrelated because hormones, such as vitamin D and parathyroid hormone (PTH), regulate the metabolism of both minerals. Some experts question whether the dietary data collection instruments used by NHANES and other large population-based studies capture true dietary phosphorus intakes because these surveys do not account for the additional contributions of phosphate additives in foods [33,34]. As a result, there is no official tolerable upper intake level (UL) set for phosphorus. Vitamin D can also help to decrease inflammation of gums which is associated with periodontal (gum) disease*.

A meta-analysis of 9 cohort studies in 199,289 patients aged 50–73 years with end-stage renal disease showed, for example, that patients on dialysis with the highest phosphate levels (greater than 5.2–7.5 mg/dL, depending on the study) had a 39% greater risk of all-cause mortality during 12 to 97.6 months of follow-up than those with normal phosphate levels (defined in the analysis as 3.0–5.5 mg/dL, depending on the study) . Institute of Medicine, Food and Nutrition Board. Several large epidemiologic studies have also found associations between higher serum phosphate concentrations and risk of cardiovascular mortality in healthy adults. Dietary Phosphorus: Health, Nutrition, and Regulatory Aspects. Hypophosphatemic rickets: etiology, clinical features and treatment. Hormonal Control Systems Maintaining normal blood calcium and phosphorus concentrations is managed through the concerted action of three hormones that control fluxes of calcium in and out of blood and extracellular fluid: Parathyroid hormone serves to increase blood concentrations of calcium.

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). [, Cheungpasitporn W, Thongprayoon C, Mao MA, et al. Phosphate is a charged particle (ion) that contains the mineral phosphorus.
