To the Editor: Certain key information would be helpful in considering the practical application of the findings reported by Dr Ludwig and colleagues.1 Although the authors indicate that "a relatively large spread was observed in dietary fiber intake among individuals," the study did not examine the effect of fiber type, source, or form. It would be informative if Ludwig et al could supply the information about the average actual dietary fiber intake in grams per day in each of the 4 groups, the average dietary fiber intake in grams per day in the (unpublished) median quintile group, and a description of the average "typical" food intake per day in the highest quintile group.
