In March 2019 researchers from the USA published their review of the medical scientific literature to assess the role of phosphates on the risk of hypertension. Dietary phosphate, particularly inorganic phosphate, is common in the western diet with inorganic phosphates being commonly used as a flavour enhancer or preservative in processed food. Results from an increasing number of publications have revealed that dietary phosphate, particularly inorganic phosphate, appears to increase the risk of hypertension in otherwise healthy individuals and should be considered an emerging risk factor for hypertension.
