The EPIC Norfolk 24-hr dietary recall or UK EPIC-24 is an unstructured record of all food and drink, including snacks, taken over the previous day.

Participants are asked to record:

  • Approximate time of consumption
  • Quantity or amount eaten
  • Type of food
  • Cooking method
  • Whether foods are fresh, frozen, tinned etc.
  • Brand names

Participants are also asked to record the day of week represented by the recall and whether this was a typical day.

An example of a completed recall is provided as are extra sheets should they be required.

Raw data from the recall can be converted into nutrient intakes using the Data Into Nutrients for Epidemiological Research (DINER) software.
