Nutrient Reference Values (NRVs) list the recommended intakes for energy (kilojoules), protein, fats, carbohydrate, fibre, vitamins, minerals and fluid, based on age, sex and life stages. They are used by dietitians, nutritionists and other health professionals to assess the dietary needs of individuals and groups (such as residents of nursing home or pupils in boarding schools). The NRVs are revised from time to time to reflect the latest scientific research.
Australia and New Zealand has figures for 33 essential nutrients (protein, vitamins, minerals, etc) which were published in 2006 by the National Health and Medical Research Council (NHMRC). They replace the earlier set of Recommended Dietary Intakes (RDIs) which dated back to 1991.
