We appreciate the comments from Dr Archer regarding our recent report in Circulation on dietary patterns and hazard of incident acute coronary heart disease in the Reasons for Geographic and Racial Differences in Stroke (REGARDS) study. 1 However, we respectfully disagree with his characterization of the data in our report as “uncorroborated anecdotes” that are without scientific validity. Dr Archer has argued for some time that memory-based dietary assessment methods, including the food frequency questionnaire used in REGARDS and countless other highly regarded cohort studies, result in implausible dietary data because of an unknown percentage of such things as “false memories” and “lies.” Although we believe that this method remains the most suitable one for assessing diet in a large population, we acknowledge the limitations of the food frequency questionnaire and agree that energy underreporting is likely to occur with this method. However, a recent publication from a group of prominent experts in the field of diet assessment methodology provides strong, thoughtful, and well-supported counter arguments to Dr Archer’s contentions regarding the degree of this underreporting. 2 Subar et al2 conclude that the preponderance of scientific evidence does not support Dr Archer’s rather extreme claim that all self-reported diet data are worthless.We would like to point out that our report was in compliance with the 4 recommendations provided by this group regarding the collection, analysis, and interpretation of self-report dietary data. Specifically,(1) we collected self-report dietary data in the REGARDS population because the data contained a wealth of critical information about foods and beverages consumed in this population, information which was used to inform dietary pattern-coronary heart disease associations;(2) we did not use self-reported energy intake as a measure of true energy intake;(3) we did use self-reported energy intake for energy adjustment of other self-reported dietary constituents (in this case, dietary patterns) to improve risk estimates in our regression analyses; and, perhaps most importantly,(4) we acknowledged the limitations of assessing diet with a food frequency questionnaire and interpreted the results of our analyses appropriately and responsibly.
