DRI Activities Update — May 2019

Dietary Reference Intakes (DRIs) for Sodium and Potassium

Dietary Reference Intakes (DRIs) are a set of reference values used to plan and assess nutrient intakes of healthy people. They are used widely in the design and evaluation of research studies and results, in development of dietary guidelines and food guides, in planning and monitoring nutrition-related public health programs and diets for military personnel, and in patient and consumer counseling and educational programs.

The DRIs for sodium and potassium were reviewed and updated by the National Academies of Sciences, Engineering, and Medicine (NASEM) in their 2019 report, Dietary Reference Intakes for Sodium and Potassium. The report was jointly funded by the U.S. and Canadian governments to review the scientific evidence and update, as appropriate, the DRIs for sodium and potassium.

The Dietary Reference Intakes for Sodium and Potassium report draws on the 2017 NASEM report, Guiding Principles for Developing Dietary Reference Intakes Based on Chronic Disease and the Agency for Healthcare Research and Quality (AHRQ) 2018 systematic evidence review, the Effects of Dietary Sodium and Potassium Intake on Chronic Disease Outcomes and Related Risk Factors.

Guiding Principles for DRIs and Chronic Disease Endpoints

The Joint U.S.-Canadian DRI Working Group sponsored a National Academies of Sciences, Engineering, and Medicine (NASEM) consensus study in the summer of 2016 to develop guiding principles for inclusion of chronic disease endpoints to be used by committees setting future DRIs. The project built on the March 2015 workshop, panel discussions, and the workshop report. The NASEM report, Guiding Principles for Developing Dietary Reference Intakes Based on Chronic Disease, was completed and released in August 2017.

Dietary Reference Intakes and Chronic Disease Endpoint Workshop and Report

The March 2015 Dietary Reference Intake (DRI) workshop and extensive follow-up discussions informed the development of the report, Options for basing Dietary Reference Intakes (DRIs) on chronic disease endpoints: Report from a joint U.S./Canadian-Sponsored working group.
