According to the National Cancer Institute, Food Frequency Questionnaires (FFQs) are a core tool in nutritional epidemiology, capturing long-term dietary patterns. The two main types of food frequency questionnaire are classified based on whether they include portion size information, fundamentally altering their level of detail and data utility.

According to the INDDEX Project, the weighed food record (WFR) is widely considered the **gold standard dietary assessment tool** for quantitative accuracy in nutritional studies. This method is crucial for validating other, less burdensome dietary data collection techniques, despite its intensive resource requirements.
