Chapter 2 - DRIs

Question 1

DRI stands for

Answer 1

dietary reference intakes

Question 2

DRI includes

Answer 2

estimated average requirements (EAR)
recommended daily allowances (RDA)
adequate intakes (AI)
estimated energy requirements (EER)
tolerable upper intake levels (ULs)
adequate macronutrient distribution ranges (AMDRs)

Question 3

EARs

Answer 3

estimated average requirements
meet the needs of 50% of those in a life stage
set based on optimal intake for functional markers of the nutrient
used to evaluate the adequacy of diets of groups

Question 4

recommended dietary allowances

Answer 4

• daily nutrient intake amounts sufficient to meet the needs to nearly all individuals (97 to 98%) in a life stage
• rda = EAR times 1.2
• can only be set for nutrients with EAR
• amount to prevent deficiency and chronic diseases

Question 5

AIs

Answer 5

• ai used if more research needed for an EAR
• based on observed or experimental determined estimates of the average intake that appears to maintain a defined nutritional state
• can be used for individuals

Question 6

ULs

Answer 6

• tolerable upper intake levels
• maximum daily intake without adverse health effects
• not a goal, but a ceiling
• based on nutrient intake from all sources

Question 7

EER

Answer 7

• estimated energy requirements
• average daily energy (calorie) need for each life stage group
• energy from c,p,f,a consumbed above need = stored as body fat
• average energy intake to maintain energy balance

Question 8

AMDRs

Answer 8

• acceptable macronutrient distribution ranges
• not a DRI, established for guidance
  set for carbs, protein, fat, and essential fatty acids
• provide range of intake associated with good health and a reduced risk of chronic disease

Question 9

Carb AMDR

Answer 9

45 to 65

Question 10

Fat AMDR

Answer 10

20 to 35

Question 11

Protein AMDR

Answer 11

10 to 35

Question 12

DVs

Answer 12

daily values
- based on two sets of dietary standards
- reference daily intakes and daily reference values

Question 13

RDI

Answer 13

• standards tend to be set at the highest RDA value or AI for any life stage group

Question 14

DRVs

Answer 14

• for energy producing nutrients, cholesterol, sodium
