Colonoscopy prep: Liquid-only diets unnecessary, GI doctor says
But that leaves many solid foods that people can eat and digest without affecting the quality of their colonoscopy. A low-residue diet, one that is heavy on starch and protein and free of vegetables, is just as effective, and much less difficult to endure, than a diet restricted to clear liquids all day. (I have seen corn and seeds many times during a colonoscopy, but I have never seen a piece of chicken!)
