The National Diet and Nutrition Survey (NDNS) Rolling Programme (RP) began in 2008 and is designed to assess the diet, nutrient intake and nutritional status of the general population aged 1.5 years and over living in private households in the UK. (For details of the previous NDNS series, which began in 1992, see the documentation for studies 3481, 4036, 4243 and 5140.)

The programme is funded by Public Health England (PHE), an executive agency of the Department of Health, and the UK Food Standards Agency (FSA).

The NDNS RP is currently carried out by a consortium comprising NatCen Social Research (NatCen) (NatCen, contract lead) and the MRC Epidemiology Unit, University of Cambridge (scientific lead). The MRC Epidemiology Unit joined the consortium in November 2017. Until December 2018, the consortium included the MRC Elsie Widdowson Laboratory, Cambridge (former scientific lead). In Years 1 to 5 (2008/09 – 2012/13) the consortium also included the University College London Medical School (UCL).

Survey activities at the MRC Epidemiology Unit are delivered with the support of the National Institute for Health Research (NIHR) Cambridge Biomedical Research Centre (IS-BRC-1215- 20014), comprising the NIHR BRC Nutritional Biomarker Laboratory and NIHR BRC Dietary Assessment and Physical Activity Group. The NIHR Cambridge Biomedical Research Centre is a partnership between Cambridge University Hospitals NHS Foundation Trust and the University of Cambridge, funded by the NIHR.

The NDNS RP provides the only source of high quality, nationally representative UK data on the types and quantities of foods consumed by individuals, from which estimates of nutrient intake for the population are derived. Results are used by Government to develop policy and monitor progress toward diet and nutrition objectives of UK Health Departments, for example work to tackle obesity and monitor progress towards a healthy, balanced diet as visually depicted in the Eatwell Guide. The NDNS RP provides an important source of evidence underpinning the Scientific Advisory Committee on Nutrition (SACN) work relating to national nutrition policy. The food consumption data are also used by the FSA to assess exposure to chemicals in food, as part of the risk assessment and communication process in response to a food emergency or to inform negotiations on setting regulatory limits for contaminants.

England Sodium Survey, 2018-2019

Estimated salt intake of adults aged 19 to 64 years in England was assessed from 24-hour urinary sodium excretion of 596 adults, selected to be representative of this section of the population and to be sufficient to detect a difference of 0.5 g of salt intake compared with the previous survey in England in 2014 (using an estimate of variation from the England 2011 and 2014 surveys - see SN 8233). Urine samples were collected over seven months (November 2018 to May 2019).

The survey was carried out by NatCen Social Research (NatCen) and the National Institute of Health Research Cambridge Biomedical Research Centre (Cambridge BRC NDNS team). The latter consists of the NIHR BRC Diet, Anthropometry and Physical Activity Group and the NIHR BRC Nutritional Biomarker Laboratory hosted at the Medical Research Council Epidemiology Unit at the University of Cambridge. The survey was funded by Public Health England.

Assessment of Dietary Sodium in Adults:
The Assessment of Dietary Sodium is an add-on study to the NDNS RP, and is funded by Public Health England (PHE), an executive agency of the Department of Health, and the UK Food Standards Agency (FSA). It is carried out by a consortium comprising NatCen Social Research (NatCen) and MRC Elsie Widdowson Laboratory (MRC EWL), formerly known as MRC Human Nutrition Research (HNR). Fieldwork in Northern Ireland was carried out by fieldworkers from the University of Ulster.

The Scientific Advisory Committee on Nutrition (SACN) recommend a target reduction in the average salt intake of the population to no more than 6g per day. This figure has been adopted by the UK government as the recommended maximum salt intake for adults and children aged 11 years and over. Following publication of the SACN report in 2003, the government began a programme of reformulation work with the food industry aimed at reducing the salt content of processed food products. Voluntary salt reduction targets were first set in 2006, and subsequently in 2009, 2011 and 2014, for a range of food categories that contribute the most to the population's salt intakes.

Dietary salt intake can be assessed by measuring sodium excretion in urine. Since the level of sodium in urine fluctuates according to what was eaten at the last meal and how much fluid an individual has drunk, and because salt is the predominant source of sodium in the UK diet, a urine collection over 24 hours is accepted as being the most reliable method for assessing salt intake in the population.

Eleven urinary sodium surveys of adults aged 19-64 years have been conducted (as part of the National Diet and Nutrition Survey Rolling Programme (NDNS RP) or as stand-alone surveys) between 2000 and 2015, some covering the UK as a whole and some in a single devolved country. The surveys are included in this dataset, as follows:

• England 2006 sodium survey of adults aged 19-64 years
• Scotland 2006 sodium survey of adults aged 19-64 years
• Wales 2007 sodium survey of adults aged 19-64 years
• UK 2008 sodium survey of adults aged 19-64 years
• Scotland 2009 sodium survey of adults aged 19-64 years
• England 2011 sodium study

This study was a follow-up of National Diet and Nutrition Survey Rolling Programme (NDNS RP) participants and aimed to describe, and assess the impact of the COVID-19 pandemic on, the diet and physical activity of people in the UK in 2020. Self-reported diet and physical activity data was collected between August and October 2020 for around 1,000 adults and children which was compared with their diet and activity data obtained at the time of their original NDNS RP interview. Data on food security, financial security and changes in dietary and health-related behaviours since the start of the COVID-19 pandemic in the UK in February 2020 were also collected in this study (but not previously in the NDNS RP) through a web questionnaire with the aim of helping to understand the context for any changes in diet and activity. Participants were also asked to complete 4 online dietary recalls over a 2 to 3 week period to assess their current diet. This was compared with their reported diet when originally assessed in the NDNS RP (on average 2 years 7 months earlier). Adults were also asked to complete a Recent Physical Activity Questionnaire (RPAQ), again to compare with their reported physical activity when originally assessed in the NDNS RP.

Latest edition information

For the second edition (September 2022), the Food Level dietary data file has been replaced with a new version, with the variable 'FoodNumber' added. An Excel format nutrient database has also been added to the study, and the documentation updated accordingly.

The main NDNS study can be found under SN 6533.

Main Topics:

The study focuses on diet and physical activity during Covid-19, following up participants who completed the main NDNS between 2016 and 2020.

The last national survey of diet and nutrition in adults was the Dietary and Nutritional Survey of British Adults carried out in 1986/87 (held at UKDA under SN 2836). The changes in eating habits and lifestyles noted in that survey have continued throughout the intervening years. Increasing numbers of people are travelling and taking holidays abroad, and with increased multi-culturalism this has led to a greater variety of foods available. Increasing demands on people's time and longer working hours have led to greater demand and availability of pre-prepared and convenience foods. There has also been an increase in eating outside the home. There was a need, therefore, to assess the impact of such changes on diet and nutrition among adults, to update the findings of the 1986/87 Adults Survey and to complete the NDNS cycle by conducting a survey on adults aged 19 to 64 years.

The survey of adults aged 19 to 64 years aimed to collect data on diet through a questionnaire and a seven-day weighed intake record for a nationally representative sample living in private households in Great Britain. The study also included a seven-day bowel movement record, a seven-day physical activity diary, anthropometric and blood pressure measurements, a 24-hour urine sample and a blood sample. The Food Standards Agency nutrient databank, which is used to convert food weights into nutrient intake, has also been deposited with this study.

Derivation of energy expenditure in a subsample of participants in Years 6 and 7 of the NDNS RP.

The taste of foods is a key factor for adolescents' food choices and intakes, yet, exploring taste characteristics of adolescents' diet is limited. Using food records for 284 adolescents (10–19 years old) from the National Diet and Nutrition Survey (NDNS), year 9 (2016–2017), we classified diets according to taste. Tastes for each food consumed were generated from a previous survey that asked participants to allocate one main taste to each food. Responses from that survey were processed and included in a Hierarchical Cluster Analysis (HCA) to identify taste clusters. The resulting tastes were then applied to the adolescents' food records in the NDNS. For each individual, the total weight of food per day for each taste was calculated. A linear regression model was used to explore dietary intakes from each taste. Findings reveal that adolescents' daily energy intake was highest (34%) from foods that taste sweet. Sweet foods were the main calorie contributors at breakfast and daytime snacking, while energy intake from neutral-tasting foods was higher at lunch and dinner. Sweet food intake was significantly positively associated with higher energy, sugar, and fat intakes. For each percentage increase in sweet foods, energy increased by 10 kcal/d (95% CI 6, 15; P < 0.01). Savory food intake was lower in carbohydrates and sugars; with neutral food consumption inversely associated with energy, carbohydrate, sugars, saturated and total fat. Higher salty food intake was linked to higher saturated fat as well as sodium consumption. Sweet and neutral foods dominate the UK adolescent diet, followed by savory tastes. Balancing the contributions of different tasting foods could assist in improving adolescent diet quality.

The survey was designed to meet the aims of the National Diet and Nutrition Survey (NDNS) programme in providing detailed information on the current dietary behaviour and nutritional status of those aged 65 and over. The NDNS of people aged 65 and over was based on a sample of approximately 1,300 people living in the community and approximately 400 people living in institutions in Great Britain.

In the United Kingdom, the diet and nutritional status of the general population is
monitored by the National Diet and Nutrition Survey (NDNS) programme (held at the UK Data Archive under GN 33275). Results from the NDNS surveys indicate that differences exist in food consumption and nutritional status between lower and higher social economic groups.

The Low Income Diet and Nutrition Survey (LIDNS) was commissioned to provide for the first time robust, nationally representative, baseline data on food consumption, nutrient intake and nutritional status and factors affecting these in low-income/materially-deprived consumers. Data were collected between 2003 and 2005 and the survey report was published in July 2007. The survey included over 3,700 adults and children throughout the UK and had a number of components. It collected detailed quantitative information on food consumption, which was used to assess nutrient intakes. Physical measurements (e.g. height, weight, blood pressure) were also taken, and a blood sample for analysis of nutritional status indices. Finally, information on socio-economic, demographic and lifestyle characteristics was collected in a detailed interview and assessments of physical activity and oral health were made by questionnaire.

Specific aims of LIDNS were to

• provide quantitative data on the food and nutrient intakes, sources of nutrients and nutritional status of low-income groups
• describe the characteristics of individuals with intakes of specific nutrients above or below the national average
• assess the diets of low-income consumers to determine the extent to which they are sufficiently nutritious
• evaluate the extent to which the diets of low-income consumers vary from expert recommendations
• provide physical measurements of health-related factors closely associated with diet, namely height, weight and other anthropometric measurements and blood pressure for a representative sample of low-income individuals
• measure blood indices that provide evidence of nutritional status or dietary biomarkers
• assess physical activity levels of low-income groups
• provide basic information on smoking and oral health status in relation to diet
• examine the relationship between dietary intake and factors affecting food choice in low-income groups
• examine possible relationships between diet and risk factors in later life.

The dataset contains Normal, DGA and Tunneling domain names: i. the total number of normal domains are conformed by the Alexa top one million domains, 3,161 normal domains provided by the Bambenek Consulting feed, and another 177,017 normal domains; ii. the DGA domains were obtained from the repositories of DGA domains of Andrey Abakumov and John Bambenek, corresponding to 51 different malware families; iii. the DNS Tunneling consist of 8000 tunnel domains generated using a set of well known DNS tunneling tools under laboratory conditions: iodine, dnscat2 and dnsExfiltrator.

The dataset is described in the paper: Palau, F., Catania, C., Guerra, J., García, S. J., & Rigaki, M. (2019). Detecting DNS threats: A deep learning model to rule them all. In XX Simposio Argentino de Inteligencia Artificial (ASAI 2019)-JAIIO 48 (Salta).

Proportion of the population who, when surveyed, reported that they had eaten the recommended 5 portions of fruit and vegetables on a usual day. This is the weighted number of respondents aged 16 and over, with valid responses to the question 'How many portions of fruit and vegetables did you eat yesterday?', eating at least 5 portions of fruit and vegetables in the previous day.

All analyses for this indicator have been weighted to be representative of the population of England. These indicators use data from the Sport England Active Lives (AL) survey. These indicators were not intended to be, and should not be, compared directly with other sources of diet data. The AL questions are more simplistic than those used in other sources e.g., National Diet and Nutrition Survey (NDNS) or Health Survey for England (HSE). Estimates from the different surveys are not directly comparable as the data collection methodologies are different.

For the HSE, participants are asked numerous questions, including separate questions about fruits, vegetables, and pulses, and portion sizes. For the NDNS, data are collected using food diaries. Foods are then broken down to their component parts and fruit and vegetable portions are calculated. The method used in AL enables responses from a very large sample to be collected which means we can present data for each local authority which cannot be done using other sources.

The main purpose of the data set used for the PHOF indicators is to enable comparisons between areas and to measure progress. Latest update presents data from Active Lives for the period mid-November to mid-November. The current estimates (2020 to 2021 onwards) are not comparable with the previous estimates (between 2015 to 2016 and 2019 to 2020) as the current estimates are consistently around 20 percentage points lower than the previous estimates. Although the estimates of those meeting the ‘5-a-day’ fruit and vegetable consumption recommendations are significantly lower from the single question, the ranking order across local authorities or inequality groups is similar.
