The National Diet and Nutrition Survey (NDNS) rolling programme is a continuous, cross-sectional survey funded by the Food Standards Agency and Public Health England. It is designed to collect detailed, quantitative information on the food consumption, nutrient intake and nutritional status of the general population aged 1.5 years and over living in private households in the UK. The survey covers a representative sample of around 1000 people per year. 

The report of the first National Diet and Nutrition Survey rolling programme (2008/2009) was published February 9^th 2010 and provides information on the diet and nutrient intake for adults aged 19-64 years and children aged 18 months – 3 years, 4 - 10 years and 11-18 years. The second report, combing data from 2008 – 2010 (i.e. the first two years of the rolling programme combined), was published on July 21st 2011 and has additional data for adults aged 65⁺. The third report, combining data from 2008/2009 – 2011/2012 (Years 1-4) was published on 14^th May 2014. The fourth report, combining data from 2012/2013 and 2013/2014 (Years 5 & 6) was published on 9th September 2016. The fifth report, combining data from 2014/2015 and 2015/2016 (Years 7 & 8) was published on 16th March 2018.

The rolling programme provides detailed food consumption data essential to support government activities related to health. It is the primary method for monitoring salt, sugar and saturated fat intakes and is also key to monitoring progress on diet and nutrition objectives of UK health departments.

Note that the NDNS programme does not collect information on salt added at the table or during cooking.
