Quizplus · Accepted Answer

The food frequency questionnaire (FFQ) is considered to be the method of choice for research on diet-disease relationship in large cohorts. This method is able to assess the usual intake of a large number of nutrients and foods over time, making it suitable for large-scale studies. FFQs typically ask participants to report the frequency and portion size of foods and beverages consumed over a specific time period, such as the past year. They have been validated against other dietary assessment methods and biomarkers, and are often used in cohort studies to investigate associations between diet and chronic diseases such as cancer, cardiovascular disease, and diabetes.
