differs. A more detailed discussion of the origin and framework of the DRIs is presented in Appendix A. Recommended intakes for the nutrients examined to date are presented at the end of this book.
The introduction of multiple dietary reference intakes—the EAR, RDA, AI, and UL—requires that applications for each be carefully developed and clearly explained. Box S-2 provides a brief introduction to appropriate uses of the DRIs for assessment, but it lacks the detail needed for their application (see Chapter 3, Chapter 4, Chapter 5, Chapter 6 and Chapter 7).
Various professionals applying the former RDAs and RNIs—nutrition researchers, policy makers, nutrition educators, epidemiologists, and many others—may need guidance in using and interpreting
Box S-2 Uses of DRIs for Assessing Intakes of Individuals and Groups
EAR = Estimated Average Requirement
RDA = Recommended Dietary Allowance
AI = Adequate Intake
UL = Tolerable Upper Intake Level
a When the AI for a nutrient is not based on mean intakes of healthy populations, this assessment is made with less confidence.
