NUTRITION (C787) STUDY GUIDE

Document Content and Description Below

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.
