Is the Study Flawed?

Abstract

I commend Cohen and colleagues1 for taking another look at the practice of managing patients with chronic nonspecific diarrhea (CNSD) with elimination diets. However, their report proposes yet another abnormal diet for this condition and I feel that we should be sure that this treatment is truly efficacious before it is used as widely as the dietary practices which it is intended to replace. For this reason, I wish to point out some possible serious flaws in the study presented.
