Food Frequency Questionnaire

A Food Frequency Questionnaire (FFQ) is a dietary assessment tool that asks individuals to report how often they typically eat or drink specific foods and beverages over a certain period, such as the past month or year. It helps researchers and healthcare professionals estimate overall dietary patterns and nutritional intake without needing detailed daily records. The FFQ is useful for large studies because it is quick to complete and provides valuable insights into eating habits, which can be linked to health outcomes or nutritional status.
