Yes, phosphorus is vegan. In fact, phytate, the compound present in many plant foods, is the principal storage form of phosphorus in numerous vegan diet staples—cereals, legumes, nuts and seeds. Phosphorus supplements are vegan. While phosphorus was initially acquired from bone ash, world production of the mineral switched sometime in the s to other methods of manufacturing—e. Phosphorus supplementation is rarely needed and may have negative health effects. Phosphate supplements typically come with other minerals. While OTC supplements are available, self-supplementation by consumers is discouraged as it may place them at risk for chronic PTH elevation and bone loss. Not exactly healthy, but soft drinks are an honorable mention.
Patients with advanced chronic kidney disease CKD are in positive phosphorus balance, but phosphorus levels are maintained in the normal range through phosphaturia induced by increases in fibroblast growth factor FGF23 and parathyroid hormone PTH. However, the protein source of the phosphate may also be important. During the last 24 hours of each 7-day diet period, subjects were hospitalized in a research center and urine and blood were frequently monitored. The results indicated that 1 week of a vegetarian diet led to lower serum phosphorus levels and decreased FGF23 levels. The inpatient stay demonstrated similar diurnal variation for blood phosphorus, calcium, PTH, and urine fractional excretion of phosphorus but significant differences between the vegetarian and meat diets. Finally, the hour fractional excretion of phosphorus was highly correlated to a 2-hour fasting urine collection for the vegetarian diet but not the meat diet. In summary, this study demonstrates that the source of protein has a significant effect on phosphorus homeostasis in patients with CKD. Therefore, dietary counseling of patients with CKD must include information on not only the amount of phosphate but also the source of protein from which the phosphate derives. Disturbances in mineral metabolism are common complications of chronic kidney disease CKD, beginning at approximately CKD stage 3 and 4. The damaged kidney is unable to fully excrete a phosphorus load, which leads to compensatory secondary hyperparathyroidism and elevations in fibroblast growth factor FGF23 in an attempt to increase urinary phosphorus excretion to maintain phosphorus balance 1, 2.
Therefore, grain-based vegetarian diets may theoretically lead to decreased phosphorus absorption compared with meat- or casein-based diets. National Center for Biotechnology Information, U. Get your favorite articles delivered right to your inbox! Phosphoric acid contains a small amount of the mineral phosphorus. Clin J Am Soc Nephrol. It also supports our kidneys in filtering out waste and plays an important role in how our body uses and stores energy. Each level was given a colored edge with dark green at the base, followed by light green, yellow, light orange, dark orange, and red. See ” Source matters: from phosphorus load to bioavailability. Long term high intakes of sodium may lead to hypertension high blood pressure and other cardiovascular diseases.
