Questions: Multiple Cholce Question Which of the Dietary Reference Values assumes a population's average daily intake of a nutrient is adequate because no deficiency diseases are present? Estimated Aंverage Requirement Adequate Intake Recommended Dietary Allowance Tolerable Upper Intake Level

The answer is the second one (B): Adequate Intake.

Explanation for each option:

1. Estimated Average Requirement (EAR): This is the average daily nutrient intake level estimated to meet the requirement of half the healthy individuals in a particular life stage and gender group. It does not assume adequacy for the entire population.

2. Adequate Intake (AI): This is used when there is not enough evidence to develop an EAR and subsequently the Recommended Dietary Allowance (RDA). AI is set at a level assumed to ensure nutritional adequacy; it is based on observed or experimentally determined approximations of nutrient intake by a group of healthy people. The presence of no deficiency diseases in the population suggests that the average intake is adequate.

3. Recommended Dietary Allowance (RDA): This is the average daily dietary nutrient intake level sufficient to meet the nutrient requirement of nearly all (97-98%) healthy individuals in a particular life stage and gender group. It is more specific and based on more data than AI.

4. Tolerable Upper Intake Level (UL): This is the maximum daily intake unlikely to cause harmful effects on health. It is not related to ensuring adequacy but rather to preventing toxicity.

Summary: Adequate Intake (AI) is the Dietary Reference Value that assumes a population's average daily intake of a nutrient is adequate because no deficiency diseases are present.
