Male crossbred broiler-type chickens were fed graded levels of dietary phosphorus from hatching to 4 weeks of age. Plasma inorganic phosphorus and plasma inorganic calcium were determined on aliquots of blood plasma samples taken when the chickens were 4 weeks of age. The level of plasma inorganic phosphorus decreased when the chickens were fed low levels of dietary phosphorus. The level of plasma inorganic calcium was inversely related to the plasma inorganic phosphorus level. Regression equations were different for each of the four dietary phosphorus levels fed. The sum of plasma inorganic phosphorus and plasma inorganic calcium was very similar for the four treatments.

The Impact

Abstract Context Hyperphosphatemia and high levels of fibroblast growth factor 23 (FGF23) are risk factors for cardiovascular events in patients with chronic kidney diseases. However, the impact of an inorganic phosphorus additive in healthy people is largely unknown. Objective We aimed to investigate the acute effect of excessive dietary phosphorus administered as sodium dihydrogen phosphate on the postprandial levels of Pi and FGF23 and the response to food. Methods This study was a double-blind placebo-controlled crossover study with 29 healthy male and female participants from the general community who were administered a single dose of either 700 mg phosphorus (NaH2PO4) or a sodium-adjusted placebo in combination with a test meal. Postprandial plasma levels of Pi and FGF23 were measured. Results Compared with placebo, oral phosphorus increased the plasma Pi level, which remained elevated during the ensuing 8 hours (at 480 minutes: 1.31 vs 1.16 mmol/l; P < 0.001), increased urinary Pi (iAUC0-480 789 vs 95 mmol/mmol; P < 0.001), reduced tubular Pi reabsorption (iAUC0-480 −31.5 vs −6.2; P < 0.001), decreased urinary calcium (iAUC0-240 30.6 vs 53.0 mmol/mmol; P = 0.009), and stimulated the release of parathyroid hormone (iAUC0-480 2212 vs 768 ng/l; P < 0.001). However, the FGF23 levels did not change. Postprandial levels of glucose, insulin, and lipids were not substantially affected by phosphorus vs placebo. Conclusion An oral phosphorus load can induce elevated postprandial levels of circulating Pi for hours in healthy subjects, despite rapid homeostatic counterreactions. FGF23 levels and the postprandial response to food were not affected.
