• From 1941 to 1989, the Institute of Medicine’s Food and Nutrition Board (FNB) released the Recommended Dietary Allowances or RDAs. The RDAs are a single set of nutrient specific values. During deliberations in the mid- 1990’s the FNB decided to replace this single set of values with multiple sets of values, including: Estimated Average Requirements (EAR), Recommended Dietary Allowances (RDA), Adequate Intakes (AI), and Tolerable Upper Intake Levels, (UL) for designated age groups, physiologic states, and by sex. These values are collectively referred to as the Dietary Reference Intakes, or DRIs.
