food frequency methods

Food frequency methods are tools used in nutrition research to assess how often people eat specific foods over a certain period, like weeks or months. Participants report their usual intake by indicating how frequently they consume items such as fruits, vegetables, or snacks—ranging from daily to rarely or never. This approach helps researchers estimate overall dietary patterns and nutrient intake without needing detailed daily records. It’s useful for identifying connections between eating habits and health outcomes, providing a practical way to gather diet information efficiently for large groups.
