Which DRIs component is designed to meet the needs of nearly all healthy individuals in a life stage and gender group?

• A. EAR
• B. RDA
• C. AI
• D. UL

Answer: (B)

The idea being tested is that the Recommended Dietary Allowance is the nutrient intake level designed to meet the needs of nearly all healthy individuals in a specific life stage and gender group. The RDA is set to cover about 97–98% of people by pulling from the estimated average requirement and adding a safety margin, so programs and individuals can plan diets that are very likely to be adequate. This distinguishes it from the Estimated Average Requirement, which targets about half the population, and from AI, used when there isn’t enough data to estimate an EAR/RDA. The UL represents the maximum intake unlikely to cause adverse effects, not a goal for daily intake.
