According to the World Health Organization (WHO), malnutrition—including undernutrition, micronutrient deficiencies, and overnutrition—is a global concern affecting every country. The primary purpose of the dietary survey is to systematically assess food and nutrient consumption patterns within populations or individuals to address these and other nutrition-related issues.

According to extensive research, food frequency questionnaires (FFQs) are widely utilized in nutritional studies due to their cost-effectiveness and capacity to gather long-term dietary data. This established method provides significant benefits for both large-scale epidemiological research and individual clinical assessments, offering insights into habitual eating habits over months or even a year.

According to the National Cancer Institute, validated food frequency questionnaires (FFQs) have been used for decades in large epidemiological studies to estimate long-term dietary intake and its relationship with chronic diseases. A validated food frequency questionnaire is a specialized dietary assessment tool that has been rigorously tested and proven to accurately measure the typical food and nutrient intake within a specific population group over a defined period.
