Recommended Dietary Allowance
The RDI is based on the older Recommended Dietary Allowance (RDA) from 1968;[1] newer RDAs have since been introduced in the Dietary Reference Intake system, but the RDI is still used for nutrition labeling. The Food and Drug Administration has indicated that it plans to update the DVs based on the newer RDAs
The RDI is used to determine the Daily Value (DV) of foods, which is printed on nutrition facts labels (as %DV) in the United States and Canada, and is regulated by the Food and Drug Administration (FDA) and Health Canada respectively.
