A food record or food diary is a detailed description of all foods and beverages consumed over a period of three to seven days.

Documented Multiple-Day Food Records

The participant records foods and beverages at the time they are consumed in special booklets provided by the Nutrition Assessment Shared Resource (NASR). Prior to completing the food record, the participant meets with trained study staff to receive detailed instruction on food recording procedures. After completing the food record, the participant meets with study staff again to review and document the information reported in the food record. Study staff then send the reviewed and documented food record to NASR for coding and analysis using the University of Minnesota’s Nutrition Data System for Research (NDSR).

Undocumented Multiple-Day Food Records

For an undocumented food record, the participant receives less instruction on food recording procedures and does not meet with study staff to review and document the completed food record. Study staff send the food record, as completed by the participant, to NASR for coding and analysis using NDSR.

Two studies evaluated a self-administered 3-day food record protocol where the dietary intake data were analyzed both before (undocumented) and after (documented) additional information was obtained from the study participant. Results of these studies suggest that the use of undocumented food records is feasible for use in large cohort studies. (See sample undocumented multiple-day food record booklet.)
