FETA is an open source, cross-platform tool that processes dietary data from the food frequency questionnaire used by the European Prospective Investigation into Cancer and Nutrition Norfolk (EPIC-Norfolk) and automatically generates a spreadsheet containing energy, nutrient and food group intakes.
All the materials required to download and use FETA, including the EPIC-Norfolk food frequency questionnaire, dietary analysis software, and supporting materials, are currently hosted on an external website administered by the University of Cambridge Department of Public Health and Primary Care : http://www.srl.cam.ac.uk/epic/epicffq/
