Which measure best describes the amounts of nutrients that should be consumed by the population?

  • A. The Dietary Reference Intakes, as they provide a set of nutrient intake values for healthy people in the United States and Canada
  • B. The Tolerable Upper Intake levels, as they indicate the maximum daily amount of a nutrient considered safe for most healthy people
  • C. The Estimated Average Requirements, as they reflect the average daily amount of a nutrient needed to maintain a specific function in half of the healthy individuals of a population
  • D. The Recommended Dietary Allowances, as they represent the average daily amount of a nutrient considered adequate to meet the known nutrient needs of practically all healthy individuals
Correct Answer: D

Rationale: The Recommended Dietary Allowances (RDAs) are the best measure to describe the amounts of nutrients that should be consumed by the population. RDAs represent the average daily intake level that meets the nutrient requirements of nearly all (97-98%) healthy individuals in a particular life stage and gender group. Choice A, the Dietary Reference Intakes, provide a set of nutrient intake values but do not specifically address the average daily amount of a nutrient considered adequate for practically all individuals. Choice B, the Tolerable Upper Intake levels, focus on the maximum daily amount of a nutrient deemed safe for most healthy people, not the average daily amount needed. Choice C, the Estimated Average Requirements, reflect the average daily amount of a nutrient needed by half of the healthy individuals, which is not as comprehensive as the RDAs that cater to nearly all healthy people.
