The National Diet and Nutrition survey data assesses the diet, nutrient intake and nutritional status of the general population in the UK.
The NDNS is a continuous cross-sectional survey, designed to assess the diet, nutrient intake and nutritional status of the general population aged 18 months upwards living in private households in the UK. It involves an interview, a four-day dietary diary and blood and urine samples. The results are used to develop policy and monitor progress towards public health objectives on diet and nutrition, such as Responsibility Deal Food Network pledges on trans fat intakes. The data is also used to compare eating habits with UK dietary recommendations on healthy, balanced diets and nutrient intakes.
