According to the National Cancer Institute, food frequency questionnaires (FFQs) are one of the most common dietary assessment methods in large-scale epidemiological studies. The most significant advantage of using food frequency questionnaires to assess nutritional status is their ability to capture long-term, habitual dietary patterns, which is critical for studying chronic diseases that develop over many years.

According to the National Cancer Institute, the 24-hour dietary recall (24HR) provides detailed information on foods consumed and is a cornerstone of large-scale national surveys. An important benefit of using a 24-hour recall to assess diet is its ability to minimize the alteration of typical eating habits, also known as reactivity, ensuring more accurate data reflecting a person's normal intake. This low-impact method offers several key advantages for researchers and dietitians.
