Chapter 2 - DRIs Flashcards
1
Q
DRI stands for
A
dietary reference intakes
2
Q
DRI includes
A
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)
3
Q
EARs
A
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
4
Q
recommended dietary allowances
A
- 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
5
Q
AIs
A
- 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
6
Q
ULs
A
- tolerable upper intake levels
- maximum daily intake without adverse health effects
- not a goal, but a ceiling
- based on nutrient intake from all sources
7
Q
EER
A
- 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
8
Q
AMDRs
A
- 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
9
Q
Carb AMDR
A
45 to 65
10
Q
Fat AMDR
A
20 to 35
11
Q
Protein AMDR
A
10 to 35
12
Q
DVs
A
daily values
- based on two sets of dietary standards
- reference daily intakes and daily reference values
13
Q
RDI
A
- standards tend to be set at the highest RDA value or AI for any life stage group
14
Q
DRVs
A
- for energy producing nutrients, cholesterol, sodium
