Question 2

What is RNI?

Answer 2

Reference nutrient intake

- amount of nutrient that is enough to enure that needs of nearly all the group 97.5% are being met

Question 3

What is the estimate average requirement (EARs)?

Answer 3

estimate of average requirement for energy, for nutrient

- approx. 50% of the population will need less and 50% will need more energy

Question 4

What is the lower reference nutrient intake (LRNI)?

Answer 4

amount of nutrient that is enough for only small number of people who have low requirements (2.5%)
- majority of population need more

Question 5

Answer 5

when there’s insufficient evidence to set an EAR, RNI or LRNI
