The Food and Drug Administration (FDA or we) is issuing a final rule to amend our standard of identity regulations that specify salt (sodium chloride) as a required or optional ingredient to permit the use of salt substitutes in standardized foods, to reduce the sodium content. Reducing sodium may help reduce the risk of hypertension, a major risk factor for heart disease and stroke. The rule will help support a healthier food supply by providing flexibility to facilitate industry innovation in the production of standardized foods lower in sodium while maintaining the basic nature and essential characteristics of the foods. This rule is effective 14 December 2026. The incorporation by reference of certain material listed in this rule is approved by the Director of the Federal Register as of 14 December 2026.
