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in the (unpublished) median quintile group, and a description of the average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.
