In a nutrition assessment, which method estimates habitual intake using multiple 24-hour recalls or food records?

• A. Single 24-hour recall
• B. Food frequency questionnaire
• C. Diet history interview
• D. Multiple-pass 24-hour recall

Answer: (D)

Estimating habitual intake relies on collecting intake data across several days to average out day-to-day variation, and using a structured interviewing process to maximize recall accuracy. The multiple-pass 24-hour recall does precisely this: it guides the respondent through several passes to capture all foods and beverages eaten on the previous day, prompting for forgotten items, portion sizes, and preparation methods. When this approach is repeated on multiple days (or used with parallel food records), the resulting data reflect usual intake across days, and can be analyzed to estimate usual intake after adjusting for within-person variation. This combination of thorough day‑by‑day data and repeated administration makes it the best choice for estimating habitual intake from detailed 24-hour reports.

A single 24-hour recall provides only a snapshot of one day and doesn’t capture usual intake. A food frequency questionnaire targets long-term patterns with frequency data rather than detailed daily intake. A diet history interview seeks a broad picture of usual intake but doesn’t employ the structured, multistage probing of the multiple-pass method applied across several days.
