This tool is a comprehensive quantitative paper based food frequency questionnaire, which includes 127 questions. Using standard portion sizes, it is intended to measure the average yearly dietary intake of adults and the elderly. This tool has been validated five times.
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.
