Harvard T. H. Chan School of Public Health. Department of Nutrition.

Harvard University developed three different versions of a semi-quantitative food frequency questionnaire, available for research purposes. The questionnaire is the result of over thirty years of continued development, evaluation, refinement and re-evaluation. All three versions of the questionnaire were designed to be a self-administered questionnaire to assess intake of various nutrients. Nutrient intakes are computed by assigning a daily frequency weight.
