Nutrition Applications Flashcards
Describe the purpose and function of nutrition
The recommendation levels for specific nutrients and consist of a number of different types of recommendations.
Dietary Reference Intakes
“Dietary Reference Intakes” (DRI) is an umbrella term for four reference values
Estimated Average Requirements (EAR), Recommended Dietary Allowances (RDA), Adequate Intakes (AI), Tolerable Upper Intake Levels (UL)
Determined by a committee of nutrition experts who review the scientific literature to determine a value that meets the requirements of 50 percent of people in their target group within a given life stage and for a particular sex.
Estimated Average Requirements.
These values are set to meet the needs of the vast majority (97 to 98 percent) of the target healthy population
Recommended Daily Allowances.
True or False: The
requirements of half of the group will fall below the EAR and the other half will be above it
True
True or False: For each nutrient, a specific bodily function is chosen as the criterion on which to base the EAR?
True
What is EAR based on?
The nutrient value that maximizes health for a specific bodily function of 50 percent of people in a given target population
What is the scientific foundation upon which RDA values are set?
The EAR values
True or False: RDAs are
the same thing as individual nutritional requirements?
False. (RDA is a recommendation)
True or False: We can assume that if a person is consuming the RDA of a given nutrient, they are most likely meeting their nutritional need for that nutrient?
True. (97 to 98 percent of
the population’s needs are met by the RDA)
What is DRI?
Dietary Reference Intake
What is RDA?
Recommended Dietary Allowances.
What is AI?
Adequate Intakes
How do you find out a gauge of your true personal requirements for vitamin X?
A blood
test is necessary
When is an “Adequate Intake” created for nutrients?
When there is
insufficient consistent scientific evidence to set an EAR for the
entire population.
Where are all of the
DRI values for infants derived from?
For infants, they are AIs derived from nutrient values in
human breast milk.
What is the UL?
Tolerable Upper Intake Levels
Why was the UL established?
To help distinguish healthful and harmful nutrient intakes; in part, as a response to the growing usage of dietary
supplements
What do ULs indicate?
The highest level of continuous
intake of a particular nutrient that may be taken without
causing health problems.
True or False: When a nutrient does not have any
known issue if taken in excessive doses, it is still assigned a UL.
False
