Special Considerations

This tool is based on the questionnaire used in the US Nurses Study (Willett et al. 1985). The UK EPIC FFQ is a revised version of this tool, therefore we recommend to use the updated version. Additionally, one of the authors stated that it is unlikely any remaining copies of the tool remains.
