Dietary recall is a research method used in nutrition research to assess and evaluate an individual's dietary intake over a specific period of time, typically within the past 24 hours. Participants are asked to recall and report all foods and beverages consumed during that time period, including portion sizes and preparation methods. This information is used to analyze dietary patterns, nutrient intake, and adherence to dietary guidelines. Dietary recall is often compared to other methods such as food diaries or food frequency questionnaires to validate and improve accuracy of the data collected.
