Abstract
- Food Frequency Questionnaires (FFQ) are a method for collecting dietary data and use a context-specific food list to estimate the usual diet and understand the relationship between consumption patterns and health outcomes.
- Data from FFQs are advantageous for measuring consumption of specific foods or specific nutrients consumed by a given population.
- Because FFQs do not typically weigh foods or quantify using household utensils, they tend to not be as accurate as other quantitative dietary assessment methods (e.g. 24-hour Dietary Recalls and Weighed Food Records).
