FDNC researchers have been producing and managing data for the UK food composition dataset since 1978, and provided data and technical support for McCance and Widdowson’s (eds.) The Composition of Foods 5th (1991), 6th (2002) and 7th (2014) editions.

Since 2009, FDNC has led the multi-disciplinary consortium, funded by Public Health England (PHE), to maintain and update the UK food composition dataset.

UK FoodComp

Management of the programme of nutrient analysis surveys and associated work for the UK Composition of Foods

This was a four-year project funded by the Public Health England (formerly Department of Health) that finished in 2014 and aimed to:

  • Review and revise out-of-date foods and food groups within the UK food composition nutrient dataset by carrying out three analytical surveys;
  • Update the online Composition of Foods Integrated Dataset (CoFID) using new and previously unpublished data, and promote its visibility and use to a wider audience;
  • Publish the 7th edition of McCance and Widdowson’s (eds.) The Composition of Foods (published September 2014);
  • Work more closely with industry and other European compilers (via link to EuroFIR AISBL) to identify and exchange food composition data especially for branded foods

The food composition data underpins the National Diet and Nutrition Survey (NDNS).

FDNC collaborated closely with the British Nutrition Foundation, who support dissemination and stakeholder engagements, two analytical laboratories (Laboratory of the Government Chemist and Eurofins), and the Royal Society of Chemistry, who publish the McCance and Widdowson series of books and new eBooks.

Results and updates are widely publicised including survey reports, presentations and posters at UK science and health conferences, and various scientific publications. The project was also supported by separate FDNC and EU-funded activities on improved data quality methods, new and novel uses of food data including software and other tools to support research, and improved integration between composition and consumption data for pan-EU dietary assessment.

We welcome suggestions and comments on the current dataset from users, other interested parties and the public. We will also consider additional data sources, and potential alternative funding as well as a range of dissemination routes.

Results and published surveys

The following analytical surveys have been published:

Published surveys

Each survey contains new analytical data for around 60 composite foods. The surveys generally include foods most commonly consumed by the UK population and foods for which the market is growing. For example, the survey on biscuits, buns, cakes and pastries contains data for composite foods such as short sweet biscuits, plain digestives and jam filled biscuits.

Resources and Tools

McCance and Widdowson’s The Composition of Foods

McCance and Widdowson’s (eds.) The Composition of Foods (7th edn.; MW7) provides the most recent nutrient values for a range of commonly consumed foods in the UK.  Since the publication of the sixth edition in 2002, 12 analytical surveys have been undertaken. MW7 includes the majority of the new data from these surveys. In addition to new analytical values, all foods have been reviewed to check that the values are representative of foods currently consumed. Many processed foods have been reformulated to reduce the content of salt, sugar and fat in line with government public health initiatives and, where necessary, values have been updated with industry to reflect those changes in composition. Values for a wide range of nutrients (e.g. proximates, inorganics, vitamins, fibre and fatty acids) are provided and additional tables provide data for carotenoid fractions, vitamin E fractions and vitamin K for selected foods. AOAC fibre values have been included for a wide range of foods to enable energy calculations, including fibre for food labelling purposes.

We have worked with RSC to develop two eBooks covering the Fish and Fish Products and the Miscellaneous Foods Supplements to the 5th Edition and these are already available as part of RSC’s eBook collection.  Additional eBooks for MW6, MW7 and other supplements will be available shortly.

Online UK Composition of Foods Integrated Dataset (CoFID)

The ‘Composition of Foods Integrated Dataset’ (CoFID) was first published in 2008, and brought together for the first time all the available data in electronic format as a single, consolidated, dataset. The 2015 version is an update of the original publication, and includes all the new and recently reviewed data.

Some foods that were included in the 2008 CoFID have not been reviewed or validated in the 2015 update, and those foods are published separately in a file containing data for ‘old’ foods. These data can be used in addition to the 2015 dataset, but users should be aware that the values for some nutrients may not represent those foods as currently consumed.

Foods calculated by recipe or calculated based on another food (e.g., foods weighed with waste) have been recalculated to include the most recent data for ingredients and the dataset therefore contains some newly created codes which have not previously been published.

The CoFID lists analytical nutrient data for 2,898 foods, with a further 393 in the ‘old foods’ file. The data are divided across 13 worksheets, and include nutrient data for:

  • macronutrients
  • vitamins
  • vitamin fractions
  • minerals
  • fatty acid fractions
  • phytosterols
  • organic acids

A subset of the data has been published recently in book form as McCance and Widdowson’s The Composition of Foods seventh summary edition.

FAQs | User guide



The EuroFIR FoodEXplorer facility is an innovative interface, which can be accessed online and allows its users the simultaneous search of more than 20 standardised and specialised food composition databases (FCDB). Users have access to a wide range of European data, linking foods and nutrients through harmonised data description and associated nutrient value information.

The search facilities include options to search on food name, food description and a combination of food name and food description as well as the powerful and unique ability to compare the component values between foods from European FCDBs. Outputs can be downloaded as spreadsheets, allowing the user to manage the data as required. The FCDBs linked with EuroFIR use standardised food description (LanguaL) and standardised component and value description through the use of thesauri (standard vocabularies) to achieve a fully standardised approach linking between data in the various European FCDBs.


The quality of food composition data depends on many factors including the tools used to manage the data. ETH Zürich (Switzerland, developed FoodCASE software in collaboration with EuroFIR compiler organisations – organisations that are responsible for developing and maintaining national food composition resources – as part of a project defining, categorising and monitoring food composition data quality.

FoodCASE manages food composition data at several levels (original, aggregated and published data), which are implemented as independent modules, and interconnected by user-choices and recipe calculations. FoodCASE collects meta-information (e.g. date created, author) to ensure food composition data fully documented, and facilitates data sharing and exchange online by using a standardised data format. It also supports pre-defined thesauri – set ways in which foods etc. are described – such as LanguaL and EuroFIR thesauri and can be extended to include others (e.g. INFOODS tagnames or country-specific thesauri).

The overarching research goal was the creation of a data quality framework that minimised human errors by leading the data input through standardised templates emphasising mandatory and quality increasing information. The data quality framework also maximised computer-derived assistance in evaluating FCD quality, including calculations, visualisations and interpretation as well as the identification of deficiencies. FoodCASE supports platform-independent, concurrent user access (web or local), is based on open-source technologies, and has the potential to use multiple languages and data flagging for advanced data filtering.

Currently, FoodCASE is being tested for implementation by several countries including the Netherlands, Portugal, Germany and the UK.
