Dietary planning Flashcards
what is the Estimated Average Requirement (EAR)?
amount of a nutrient to meet needs of 50% of the population
what is the Recommended Dietary Allowance (RDA)?
Based on EAR, but encompasses needs of 97% of the population
what is the Tolerable Upper Intake Level (UL)?
Amount below which there is little chance of adverse health effect
what is Adequate Intake (AI)?
Value used if there is insufficient data or calculate RDA
what is Estimated Energy Requirements (EERs)?
Used to calculate calories to maintain stable weight
how is EER calculated?
Energy Consumed - Energy Used = 0 (Energy Balance)
Based on age, gender, weight, height and activity level
what are Acceptable Macronutrient Distribution Ranges (AMDRs)?
Carbs, Fat and Protein
what are the recommendations for carbs, fats and proteins (%)?
Carbs (45-65%)
Fat (20-35%)
Protein (10-35%)

Food frequency questionnaire
Diet history
what are Anthropometric Measurements?
ht, wt, BMI
waist circumference
wt change over time
what lab measurements are used?
Values of nutrients in blood
Markers of disease
what are the stages of nutrient deficiency?
- inadequate intake
- decreased stores and tissue levels
- altered biochemical and physiological functions
- physical signs and symptoms of deficiency
what assessment tools are used for ‘inadequate intake’ (1st stage)?
dietary evaluation:
- assess nutrient intake
medical hx, physical exam an lab tests:
- assess problems due to poor nutrient absorption, increased need or increases losses
what assessment tools are used for ‘decreased stores an tissue levels’ (2nd stage)?
lab tests:
- assess nutrient levels in blood, urine an tissues
anthropometrics:
- assess body wt and composition
what assessment tools are used for ‘altered biochem and physiological functions’ (3rd stage)?
lab tests:
- assess nutrient-dependent functions in the body
what assessment tools are used for ‘physical signs and symptoms of deficiency’ (4th stage)?
physical exam an anthropometrics:
- assess outward symptoms of deficiency
a healthy behaviour score is calculated looking at what 4 dimensions?
Smoking status, drinking habits, physical activity level and fruit and vegetable consumption
what is the Healthy Eating Food Index?
assess how food choices align with Canada’s food guide 2019
