'Dietary reference values' (DRV) are the umbrella term for a range of nutrient values that apply to a population or group, and typically consist of numerous components:
A Lower Reference Nutrient Intake (LRNI): Meets the nutritional requirements of only 2.5% of the population.
An Estimated Average Requirement (EAR): The average amount of nutrient or energy required. Approximately 50% of the population will require more and 50% will require less.
A Reference Nutrient Intake (RNI): The amount of a nutrient sufficient to meet the needs of 97.5% of a population (calculated from the EAR + 2 SD)
Safe Intake (SI): Used in place of RNI when there is insufficient data available to set an RNI. A safe intake is likely to meet the needs of the majority of the population without causing any adverse effects of excess intake.
Safe Upper Limit (SUL): The maximum amount of a nutrient known to be safe to intake. Habitually consuming nutrients above the SUL is not recommended and can cause toxic effects in some cases.
Choose which Dietary Reference Values you wish to use from the ‘DRV source’ drop down when setting up your client. The target intakes and ranges for nutrients on the report will be based on this selection. There are numerous options from International sources built in to Nutritics. You can also set your own targets using the DRV editor (see custom DRV section).
Built-in DRV’s in Nutritics include:
UK/SACN 2015: The Committee on Nutrition Aspects of Food and Nutrition Policy (COMA) with latest updates from the Scientific Advisory Committee
EFSA 2017: European Food Safety Authority Guidelines
EU/Nordic: The Nordic Nutrition Register (NNR)
USA: The Food Nutrition Board from the Institute of Medicine (IOM)
NZ/AUS: The National Health and Medical Research Council (NHMRC)
EU: The EU Reference Intakes used in Food Labelling
FDA: The US Daily Values for labelling in the US and surrounding territories
A Nutritics recommendation which combines macronutrient guidelines from American College of Sports Medicine (ACSM) with suggested dietary micronutrient targets for reducing the risk of developing chronic disease from the NHMRC. The Nutritics recommendations also show lower intake limits from the NNR and upper intake limits from the highest value deemed safe from the above authorities.
