Special Considerations

It appears unlikely that any remaining copies of the tool are available. The EPIC-Norfolk study has printed 7-day diet diaries for use by other studies/projects. There is room left on the back and front of the A5 booklet to personalise the diary with your own logo, and/or notification of sponsors etc. We can provide the diaries for free but we will require you to pay postage costs. The diaries can be used with any data-entry program. Portion sizes of the photographs displayed can be provided.
