Dietary Reference Intakes (DRIs)
Umbrella term for the suite of nutrient reference values (EAR, RDA, AI, UL, CDRR) developed jointly by the United States and Canada to plan and assess diets of healthy populations and individuals.
Also: DRI, DRIs
The DRIs replaced the older single-value Recommended Dietary Allowances framework starting in 1997. They are not a single number per nutrient but a set of category values reflecting different uses: EAR for assessing population adequacy, RDA for planning individual intakes, AI when an EAR cannot be set, UL for the upper safety bound, and CDRR for intakes that reduce chronic disease risk independent of deficiency. Chapter 109 (Yaktine) details their history and limitations, particularly for chronic-disease endpoints.

Developed by the Food and Nutrition Board of the National Academies, DRIs replaced the older single-value RDAs. EAR (Estimated Average Requirement) covers 50% of a healthy population. RDA (Recommended Dietary Allowance) covers 97 to 98% and is calculated from the EAR. AI (Adequate Intake) is used when an EAR cannot be set. UL (Tolerable Upper Intake Level) is the maximum daily intake unlikely to cause adverse effects.
