Nutrition Reference Values

Question 1

NRV’s definition

Answer 1

are estimates of the requirements for groups of people and are not recommendations or goals for individual people.

Question 2

Why nutritional requirements vary

Answer 2

age
gender
level of physical activity
state of health
Some people absorb or utilise nutrients less efficiently than others and so will have higher than average nutritional requirements.

Question 3

different NRV estimates

Answer 3

Estimated average requirement (EAR)
Estimated average of x
Recommended dietary intake (RDI)
Amount you need to be well
Adequate intake (AI)
Have you had enough to be okay
Estimated energy requirements (EER)
How much carbs do I need to have the right amount of energy
Upper level of intake (UI)
When is too much going to be a problem

Question 4

Estimated average requirement (EAR)

Answer 4

the daily nutrient level estimated to meet the nutrient requirements of half the healthy individuals in different age and gender groups.
is typically used to estimate the percentage of people within a group with inadequate intakes of a nutrient.
Usually used to determine group needs.

Question 5

Recommended dietary intake (RDI)

Answer 5

The average daily dietary intake level that is sufficient to meet the nutrient requirements of nearly all healthy individuals in a particular life stage and gender group
is calculated from the EAR and is always higher than it

Question 6

Using RDI’s (2-3)

Answer 6

A guide for planning menus, ensuring they are balanced with a range of nutrients
To assess the adequacy of the diet of individuals
For nutrition labelling
For monitoring the availability of nutrients in the food supply
For planning diets for specific medical purposes

Question 7

Adequate Intake

Answer 7

The average daily nutrient intake level based on observed approximations of nutrient intake by a group of apparently healthy people that are assumed to be adequate.

Question 8

Estimated Energy Requirement

Answer 8

The average dietary energy intake that is predicted to maintain energy balance in a healthy adult
In children and pregnant and lactating women, the EER is taken to include the needs associated with the secretion of milk at rates consistent with good health.

Question 9

Upper level of Intake

Answer 9

The highest average daily nutrient intake level likely to pose no adverse health effects to almost all individuals in the general population.
