What are the Recommended Dietary Allowances (RDAs) and the Dietary Reference Intakes (DRIs)?

From 1941 to 1989, the IOM's FNB released the RDAs. The RDAs are a single set of nutrient-specific values. During deliberations in the mid-1990s, the FNB decided to replace this single set of values with multiple sets of values, including the EAR, RDA, AI and UL for designated age groups, physiologic states (for example, pregnancy), and by sex. These values are collectively referred to as the DRIs. Visit FNIC to access the DRI nutrient reports and tables for vitamins, elements, macronutrients, electrolytes, and water.
