HISTORY: • Over the past two decades, food frequency questionnaires have become a well-accepted method for quantitative assessment usual nutrient intake. • Many question remain about the accuracy & appropriateness of FFQ's especially when more precise estimates of actual food intake are desired.

  3. CONT, • There are, however, many practical advantages to FFQ's that motivate their use in a number of specific research applications. • Research to improve the validity of FFQ's & modify their characteristics for specific research questions is well warranted.

  4. Food Frequency Questionnaires • Assess energy and/or nutrient intake by determining how frequently a person consumes a limited number of foods that are major sources of nutrients or of a particular dietary component in question.

  5. CONT, • The questionnaires consist of a list of approximately 150 or fewer individual foods or food groups that are important contributors to the population's intake of energy and nutrients. • Respondents indicate how many times a day, week, month, or year that they usually consume the foods.
