Which method is used to determine typical dietary pattern over a period of time?

• A. Food Frequency Questionnaire
• B. Diet Records
• C. 24-Hour Recall
• D. Calorie Count

Answer: (A)

The main idea is to capture how often people eat various foods over an extended period, so the assessment reflects usual dietary patterns rather than a single day’s intake. A Food Frequency Questionnaire does this by asking how often a wide list of foods is consumed over a defined timespan, such as weeks, months, or a year. This approach smooths out day-to-day variability and provides a picture of habitual eating habits, which is exactly what’s needed when you want to know typical patterns.

In contrast, a diet record involves logging everything eaten for several days as it happens, giving precise short-term intake but not necessarily the long-term pattern. A 24-hour recall queries what was eaten yesterday, which can vary widely from day to day and isn’t ideal for assessing usual intake. Calorie count focuses on total energy intake, which is a metric derived from intake data but doesn’t by itself measure typical dietary patterns over time.
