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:
- Designing and evaluating research studies and results
- Developing dietary guidelines and food guides
- Planning and tracking nutrition-related public health programs and diets for military personnel
- Creating patient and consumer counseling and educational programs
The U.S. and Canadian governments have each formed Federal DRI Committees that work together to identify DRI needs and to coordinate government sponsorship of DRI reviews and activities. Read more about the committees and nutrient assessment for DRI review.
The U.S. and Canadian governments also jointly funded a 2019 report on the DRIs for sodium and potassium. As a follow-on to this, the National Academies of Sciences, Engineering, and Medicine (NASEM) has developed an educational webpage, Expansion of the Dietary Reference Intake Model: Learning from Sodium and Potassium. Read more about recent DRI activities.
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. The study was designed to inform principles that the committees can use to include chronic disease endpoints when 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 Intakes and Chronic Disease Endpoints 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.
