DRI Activities Update — November 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.

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 (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.

In preparation for the review of the DRIs for sodium and potassium, an Agency for Healthcare Research and Quality (AHRQ) systematic evidence review of the Effects of Dietary Sodium and Potassium Intake on Chronic Disease Outcomes and Related Risk Factors began in late summer 2016. The evidence report is expected to be publicly available in early 2018.

The NASEM DRI review of sodium and potassium is underway. The review began in fall 2017 and will draw on the NASEM report, Guiding Principles for the Inclusion of Chronic Disease Endpoints in Future Dietary Reference Intakes, and the AHRQ systematic evidence review of sodium and potassium. The review will include consideration of indicators of deficiency, inadequacy, and toxicities, as well as relevant chronic disease endpoints.
