Which statement accurately describes a 24-hour dietary recall?

• A. It estimates usual intake over months.
• B. It is collected via a food frequency questionnaire.
• C. It records only meals eaten at home.
• D. It is a detailed report of all foods and beverages consumed in the past 24 hours.

Answer: (D)

A 24-hour dietary recall is a detailed report of everything a person eats and drinks in the previous 24 hours, usually obtained with an interviewer who prompts for forgotten items and clarifies portion sizes. This approach aims to capture what was actually consumed that day, including all meals, snacks, beverages, and even condiments, regardless of where the foods were eaten. It differs from methods that estimate usual intake over longer periods, such as a food frequency questionnaire, which looks at patterns over weeks to months rather than a single day. While it provides detailed quantitative information about that specific day, it relies on memory and accurate portion estimation and may not reflect typical intake due to day-to-day variation.
