Reference Daily Intake
From Wikipedia, the free encyclopedia
The Reference Daily Intake or Recommended Daily Intake (RDI) is the daily intake level of a nutrient that was considered in 1968 to be sufficient to meet the requirements of 97–98% of healthy individuals in every demographic in the United States (where it was developed, but has since been used in other places).
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.
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.[2]
