Is it ok to eat oatmeal raisin cookies 5 days before colonoscopy?

It's generally advisable to avoid high-fiber foods, including oatmeal raisin cookies, in the days leading up to a colonoscopy. High-fiber foods can leave residue in the colon, making it harder to achieve a clear view during the procedure. Typically, a low-fiber diet is recommended for 1-3 days prior, followed by a clear liquid diet the day before. Always follow your doctor's specific instructions regarding dietary restrictions before the procedure.
