• Understand the 4 types of Dietary Reference Values used in the UK ie EARs, RNIs, LRNIs, Safe Intake.

Estimated Average Requirements (EARs)

it is a middle point reference needed for a group of people, so 50% of the group will require more and 50% will require less

Reference Nutrient Intakes (RNIs)

it is a reference nutrition intake that means 97.5% classed as almost ALL of a certain group’s nutrition intakes are being met

Lower Reference Nutrient Intakes (LRNIs)

this is the opposite of RNIs, this is enough nutrition intake to meet 2.5% of the group who have lower nutrition requirements than the majority

Safe Intake The Safe intake is used where there is insufficient evidence to set an EAR, RNI or LRNI. The safe intake is the amount judged to be enough for almost everyone, but below a level that could have undesirable effects.

• Be aware that Dietary Reference Values (DRVs) comprise a series of estimates of the amount of energy and nutrients needed by different groups of healthy people in the UK population.

as above

• Understand that RNIs are used for protein, vitamins and minerals, and are an estimate of the amount that should meet the needs of most of the group to which they apply. They are not minimum targets.

statement

• Be aware that the EAR is used in particular for energy.
