Which dietary assessment method requires individuals to record all foods and drinks over multiple days?

• A. Diet Records (Food Diary)
• B. 24-Hour Diet Recall
• C. Food Frequency Questionnaire
• D. Dietary History

Answer: (A)

Recording every food and drink consumed over several days is a diet-record, or food diary, approach. This method is prospective and asks individuals to write down everything they eat or drink at the time of consumption, often including portion sizes. Because it happens in real time, it reduces reliance on memory and can provide detailed data on actual intake across multiple days, capturing variation in daily patterns. It is typically considered highly accurate for assessing intake, though it can be burdensome to maintain and may influence eating behavior simply by the act of recording. In contrast, a 24-hour recall depends on memory of the previous day, a food frequency questionnaire estimates how often foods are eaten over a longer period without exact amounts, and a dietary history relies on retrospective reporting of usual intake. This combination of real-time recording and multi-day data is what makes diet records the best fit for the described scenario.
