Unit 2 - Nutrition Tools: Standards and Guidelines Flashcards
RDA (Recommended Dietary Allowances)
Intake goals for individuals
Define Dietary Reference Intakes (DRI)
Nutrient standards set for Canada and the U.S.
AI (Adequate Intakes)
Goals for individuals when insufficient scientific data exists to set a RDA
EAR (Estimated Average Requirements)
Intake goals for given stages of life and gender groups;
Population wide average nutrient requirements used by researchers and policy makers;
Can form the basis upon which RDAs are set
UL (Tolerable Upper Intake Levels)
Maximum amount that is safe;
Absence of a UL does not mean that it is safe to consume in any amount, but rather that insufficient data/evidence exists to set a value
AMDR (Acceptable Macronutrient Distribution Ranges)
Ranges of recommended intake for carbohydrates, fat, and protein, expressed as a percent of total daily calorie intake
Why are DRIs set?
They are designed for health maintenance and disease prevention in healthy people
they are NOT designed for restoration of health
What factors are considered in DRIs?
Body Mass Index (BMI) - reference weight and height
Age - to account for physiological changes of life cycle
Time - not based on one day of food intake, but rather an average consumption
What factors are NOT considered in DRIs?
Activity Diet Geographic Area Lifestyle Illness/Malnutrition
What indicates risk of a deficiency?
Consuming 2/3 or 66% of recommendations
