Question

Quizplus · Accepted Answer

The EAR (Estimated Average Requirement) represents the average amount of a nutrient that is estimated to meet the requirement of half of healthy individuals in a particular age and gender group. Therefore, only 50% of healthy individuals will have their physiological needs met at the level of intake represented by the EAR. The RDA (Recommended Dietary Allowance) represents the average daily amount of a nutrient that is sufficient to meet the needs of nearly all (97-98%) healthy individuals in a particular age and gender group. The AI (Adequate Intake) is used in cases where there is not enough data to establish an EAR or RDA, and represents an estimate of the amount of a nutrient that appears to maintain a defined nutritional state or health status in a particular age and gender group. The UL (Tolerable Upper Intake Level) is the highest level of daily nutrient intake that is likely to pose no risk of adverse health effects to almost all individuals in the general population.
