The WNDDS Database

The Agriculture & Food Systems Institute has compiled a catalogue of national, regional and international FCDBs to provide a comprehensive resource with information on all FCDBs. This catalogue provides relevant information on each FCDB as well as a direct link to the resource.

The information available in WNDDS includes:
  • the country/region of origin
  • contact information for the database managers
  • the number of foods and nutrients analyzed
  • the percentage of foods with specific nutrient information.
  • Users are able to easily view various categories and subcategories on each FCDB.

Database Uses

Food composition data are essential for assessing the nutritional properties of food. These data have many uses, including evaluating the nutritional variation of plants and foods, analyzing relationships between nutrient intake and disease, and establishing dietary guidelines.

Data Sources

These data are generated through various methods including analytical measurements, calculations, imputations, and borrowed data. To assemble and utilize this information, food composition tables and databases (FCDBs) have been developed to store these data. Given the diversity of dietary intake internationally, many regions and nations have developed their own FCDB to provide food composition information on foods typical to that country or region.

Methods

The information in WNDDS was obtained through a systematic review of available FCDBs. Each FCDB was initially screened for information related to each category and subcategory described in the User's Guide. After the initial review process, managers of the FCDB were contacted for further information. Managers were notified of the project goals and the information being collected. They were also informed that WNDDS would be an open access resource and all private information would be excluded. If there was no manager for the FCDB or no response to the request for further information, the initial screening served as the source of data for WNDDS. When no information was available for a specific category or subcategory, the indicator was left blank. When it was not possible to report certain indicators, the indicator was left blank.
