Final answer:
The Dietary Reference Intakes (DRI) consist of Recommended Dietary Allowances (RDA), Adequate Intakes (AI), Tolerable Upper Intake Levels (UL), Estimated Average Requirements (EAR), and Acceptable Macronutrient Distribution Ranges (AMDR), which together provide a comprehensive guide for nutrient intake.
Step-by-step explanation:
The Dietary Reference Intakes (DRI) are a set of reference values used to assess and plan for nutrient intakes and are composed of several components:
- Recommended Dietary Allowance (RDA): The amounts of nutrients needed by most (97.5%) of the population.
- Adequate Intake (AI): Used when an RDA cannot be determined and it represents a nutrient amount assumed to ensure nutritional adequacy.
- Tolerable Upper Intake Level (UL): The maximum intake level of a nutrient that is unlikely to pose risks of adverse health effects.
- Estimated Average Requirement (EAR): The intake level estimated to meet the needs of 50% of the population.
- Acceptable Macronutrient Distribution Ranges (AMDR): Ranges for the intake of energy-providing macronutrients that are associated with reduced risk of chronic disease while providing adequate intakes of essential nutrients.
The most accurate option for what makes up the DRI is:
b. Recommended Dietary Allowances (RDA), Adequate Intakes (AI), Tolerable Upper Intake Levels (UL), Estimated Average Requirements (EAR), Acceptable Macronutrient Distribution Ranges (AMDR)
