What do the acronyms DRI, UL, EAR, RDA signify? Describe how these numbers are developed and
how they are used to guide nutritional recommendations for people and populations.
* DRI: Dietary Reference Intakes. Replaced RDAs & differ from the original RDAs by incorporating
concepts of disease prevention, upper levels of intake/potential toxicity & nontraditional
nutrients. Are a set of @ least 4 nutrient-based reference values, which are the:
1. UL: Tolerable upper intake level or the highest level of continued daily nutrient intake that is
unlikely to pose an adverse health effect.
2. EAR: Estimated avg requirement. This is the median usual intake value estimated to meet the
requirements of half of the healthy individuals. Based on specific criteria of adequacy & on
careful review of scientific evidence. Not all nutrients have an EAR if no acceptable science
base upon which to define one.
3. RDA: RDA = EAR + 2 standard deviation of the requirement, which is the avg daily dietary
intake level sufficient to meet the nutrient requirement of approx. 98% of people. If there is
no EAR for a nutrient, there can be do RDA
4. AI: adequate intake. Provided if no EAR/RDA available.
* Important uses of the DRIs include personal diet planning, dietary guidance, institutional food
planning, military food/planning, planning for food assistance programs, food
labeling/fortification, developing new/modified food products, & guaranteeing food safety.
* In planning menus/diets, important to meet the RDA or AI without exceeding the UL.
