                                According to the National Institute of Diabetes and Digestive and Kidney Diseases, a clean bowel is critical for an accurate colonoscopy, and following a low-fiber diet days before is a key step in preparation. Knowing which vegetables are acceptable during this time can be confusing, but the rules center on minimizing residue to ensure a clear view for your doctor.
