24-Hour Dietary Recall and Food Record Methods

Show Summary Details


This chapter describes two methods: the 24-hour dietary recall and food record method. Topics covered include data collection methods, strengths and limitations of the two methods, reducing error in data collection, analysis of food intake data, and sources of error in nutrient calculation. The two short-term methods serve important functions in describing mean values for groups and in validating food frequency questionnaires, which are not the most commonly used method for measuring dietary exposures in epidemiologic studies.

Keywords: 24-dietary recall; food records; data collection; data collection methods; food frequency questionnaires
