Chapter 4 - Nutrient Recommendations: Tools to Design a Healthy Diet Flashcards
what are the 2 approaches to formulation nutrition recommendations in Canada?
1) Dietary Reference Intakes (DRIs) -nutrient-based
2) Canada’s Food Guide (CFG) - food-based
3 aims of the DRI committee?
1) prevent deficiencies
2) reduce chronic disease
3) promote good health
2 types of DRIs
1) DRIs for most nutrients
2) DRIs for energy and macronutrients
4 DRIs for most nutrients
1) Estimated average requirement (EAR)
2) Recommended Dietary Allowance (RDA)
3) Adequate Intake (AI)
4) Tolerable Upper Intake Level (UL)
2 DRIs for energy and macronutrients
1) Estimated Energy Requirement (EER)
2) Acceptable Macronutrient Distribution Range (AMDR)
estimated average requirement (EAR)
- an estimated amount of a nutrient
- meets the needs of 50% of people
- specific gender and life-stage group
Recommended Dietary Allowance (RDA)
- target intake for an individual
- meets the needs of 97-98% of people
- specific gender and life-stag group
- a higher value than the EAR
- EAR +2 standard deviations
- increase chances a person will meet their requirement
adequate intake (AI)
-recommended specific amount of a nutrient for an individual
when is adequate intake used?
used when there is not enough info available to set an EAR
Tolerable Upper Intake Level (UL)
- max daily intake unlikely to cause adverse health effects
- not recommended levels
- a “safe” upper limit
2 types of recommendations for energy
1) estimated energy requirements (EER)
2) Acceptable Macronutrient Distribution Ranges (AMDR)
Estimate Energy Requirements (EER)
- total kCals needed to maintain body weight
- based on several factors
Acceptable Macronutrient Distribution Ranges (AMDR)
- a range of healthy intakes
- prevent chronic disease
- proportion is as important as amount
- flexibility
what determines which food group a food is grouped in?
major nutrients
vegetables and Fruit
- carbs & fibre
- folate, vitamins A & C
- Magnesium and potassium
