RDA
Recommended Dietary Allowances
New cards
14
Adequacy. Nutrient intake goals for individuals; the average daily nutrient intake level that meets the needs of nearly all (97-98%) of the HEALTHY people in a particular life stage and gender group.
New cards
15
AI
Adequate Intake
New cards
16
Adequacy. Nutrient intake goals for individuals; the recommended average daily nutrient intake level based on intakes of healthy people in a particular life stage and gender group and *assumed* to be adequate. Set when scientific data are insufficient to allow establishment of an RDA value.
New cards
17
This is typically the number given for *children* because there is less research with children because they are a vulnerable population.
New cards
18
UL
Tolerable Upper Intake Levels
New cards
19
Safety. The highest average daily nutrient intake level that is likely to pose no risk of toxicity to almost all healthy individuals of a particular life stage and gender group.
New cards
20
Even when they set a UL, there is a buffer (marginal) before it becomes toxic.
New cards
21
EAR
Estimated Average Requirements
New cards
22
Research and policy.
New cards
23
The average daily nutrient intake *estimated* to meet the needs of *half* of the healthy individuals in a particular life stage and gender group; is used in nutrition research and policy making and is the basis upon which RDA values are set.
New cards
24
AMDR
Acceptable Macronutrient Distribution Ranges
New cards
25
Healthful ranges for energy-yielding nutrients.
New cards
26
Values for carbohydrate, fat, and protein expressed as percentages of total daily caloric intake; ranges of intakes set for the energy-yielding nutrients that are sufficient to provide adequate total energy and nutrients while minimizing the risk of chronic diseases.
New cards
27
AMDR ranges
1. 45-65% of calories from carbohydrate.
New cards
28
2. 20-35% of calories from fat.
New cards
29
3. 10-35% of calories from protein.
New cards
30
RDA Energy (AMDR) are:
1. Based on a reference person
New cards
31
2. Use chart to look up reference for: 19-30 year old female (height, weight, calories) and male (height, weight, calories)
New cards
32
3. Other ways to determine individual calorie needs
New cards
33
The DRI (the umbrella term for all of the individual recommendations) tells you these three things:
1. How much of what nutrient
New cards
34
2. Per unique person
New cards
35
3. How scientists arrive at the conclusion of those numbers
New cards
36
Establighing the DRIs using the Scientific Method:
New cards
37
Early Observation and Study: *Niacin* Example: pelle agra disease
1st hypothesis: germ, 2nd: diet. Poor got it more than the wealthy. Corn-eaters (except South America). Dr. Joseph Goldberger looked at orphanges with higher rates of pelle agre. The high protein (experimental) group got milk, buttermilk, eggs, dried beans, etc. and didn't get any more pelle agra. Did the same things in Saratorium with protein experiment. Then Dr. Conrad did research on dogs, found that if he gave them niacin acid, pelle agre went away.
New cards
38
Basically, found that it was actually a *Niacin deficiency*.
New cards
39
Updating the Dietary Guidelines for Americans (DGA)
1. Updated every 5 years by the US Department of Health and Human Services (DHSS) and the US Department of Agriculture (USDA)
New cards
40
2. Most recent released March 2016 (It's the 8th edition: 2015-2020).
New cards
41
3. Scientists have a committee to create the new guidelines based on science/research.
New cards
42
Goals of the Dietary Guidelines for Americans
