What does Estimated Average Requirements (EAR) indicate?
Understand the Problem
The question is asking for the definition or indication of Estimated Average Requirements (EAR) in the context of nutritional science. We need to identify which answer option correctly describes EAR.
Answer
EAR indicates the nutrient intake level expected to meet the needs of 50% of a population group.
Estimated Average Requirement (EAR) is the nutrient intake value estimated to meet the requirement of half (50%) of healthy individuals in a specific group.
Answer for screen readers
Estimated Average Requirement (EAR) is the nutrient intake value estimated to meet the requirement of half (50%) of healthy individuals in a specific group.
More Information
EAR is often used in nutritional planning and assessment, providing a baseline for evaluating the sufficiency of nutrient intakes in populations.
Tips
Confusing the EAR with other dietary reference intakes such as Recommended Dietary Allowance (RDA) can lead to misinterpretation. The RDA is typically higher, as it meets the needs of 97-98% of the population, unlike EAR that serves 50%.
