The key objective of the NDNS RP is the collection of high quality dietary data from a representative sample of the UK population, specifically detailed and quantitative information on food consumption, nutrient intakes and sources of nutrients. These data are vital to enable monitoring of the diet and nutritional intake of the UK population, and to provide the evidence base for developing and evaluating government policy.
The results of the NDNS RP are used to assess the adequacy of food and nutrient intake and nutritional status in different population groups. They are also used by government to develop policy and monitor progress on diet and nutrition objectives, such as work to move the public towards a healthier diet or tackling obesity. Food consumption data is also used by the Food Standards Agency (FSA) to assess exposure to chemicals in food, this informs risk assessments and the setting of regulatory limits for contaminants.
