Controversy and Debate: Memory based Methods Paper 1: The Fatal Flaws of Food Frequency Questionnaires and other Memory-Based Dietary Assessment Methods

There is an escalating debate over the value and validity of memory-based dietary assessment methods (M-BMs). Proponents argue that despite limitations, M-BMs such as food frequency questionnaires (FFQs), provide valid and valuable information about consumed foods and beverages, and therefore can be used to assess diet-disease relations and inform public policy. In fact, over the past 60 years thousands of research reports using these methods were published and used to populate the United States Department of Agriculture ’s National Evidence Library, inform public policy, and establish the Dietary Guidelines for Americans.
