part c
which component of the dri reflects the requirement of a nutrient for 50 percent of healthy americans and canadians in a specific life stage and gender?
○ ear (estimated average requirement)
○ rda (recommended dietary allowance)
○ ai (adequate intake)
○ ul (tolerable upper intake level)

Explanation:

Part A

DRI actually stands for Dietary Reference Intakes, not Daily Required Intakes. So the statement is false.

EAR (Estimated Average Requirement), RDA (Recommended Dietary Allowance), AI (Adequate Intake), and UL (Tolerable Upper Intake Level) are the components of DRI that deal with nutrient quantities for health optimization, deficiency prevention, and avoiding excess. EER (Estimated Energy Requirement) and AMDR (Acceptable Macronutrient Distribution Ranges) are about energy and macronutrient distribution, not nutrient quantity for the given purposes.

EAR (Estimated Average Requirement) is the intake level that meets the nutrient requirement of 50% of healthy individuals in a specific life - stage and gender group. RDA is for 97 - 98% of the group, AI is used when RDA can't be determined, and UL is the upper limit of safe intake.

Answer:

false
