Nurtient Refernce Values Flashcards
What does AI stand for?
Define AI
AI = adequate intake
AI is used when EAR or RDI cannot be determined and based on experimental data or estimates that are assumed to be adequate.
What does EER stand for?
What is EER used for?
EER - estimated energy requirement
EER is the average dietary energy intake that is estimated to maintain energy balance according to age, gender, weight, height and level of activity
What does BMI mean?
BMI is a measure of weight. It is calculated by dividing weight by height squared.
What does AMDR stand for?
What is AMDR used for?
AMDR - acceptable macronutrient distribution range
The AMDR is an estimate of the range for each macronutrient (expressed as a percentage) that would maximise health outcomes. For example, it is recommended that protein contributes 15/25% energ
What does the term NTV stand for?
What is the main purpose of NRVs?

What does UL stand for?
Define UL
UL - upper level of intake
UL is the highest average daily nutrient intake likely to pose no adverse health affects. As intake increases above the UL, the potential risk of adverse effects increases
What does EAR stand for?
What is EAR used for?
EAR - estimated average Requirement
EAR is the daily nutrient level estimated to meet the nutrient requirements of half the healthy individuals in different age and gender groups.
