Final answer:
The correct Dietary Reference Intakes (DRIs) include Estimated Average Requirements, Recommended Dietary Allowances, Adequate Intakes, and Tolerable Upper Intake Levels.
Step-by-step explanation:
The Dietary Reference Intakes (DRIs) include several reference values that provide quantitative advice to health professionals. Among these are:
Estimated Average Requirements (EAR): The intake level estimated to meet the requirements of 50% of the individuals in a specific group.
Recommended Dietary Allowances (RDA): The average daily dietary intake level sufficient to meet the nutrient requirements of nearly all (97.5%) healthy individuals in a particular life stage and gender group.
Adequate Intakes (AI): A recommended intake value based on observed or experimentally determined estimates of nutrient intake by a group of healthy people that are assumed to be adequate when an RDA cannot be determined.
Tolerable Upper Intake Levels (UL): 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.
Therefore, the correct answer to the student's question is: 'Estimated Average Requirements, Recommended Dietary Allowances, Adequate Intakes, and Tolerable Upper Intake Levels'.
