Colonoscopy Prep: What to Eat (and Avoid) Before Your Procedure

It is generally recommended that you follow a clear liquid diet for 2 days before a colonoscopy. This means that you should avoid solid foods, including steak. Clear liquids include water, broth, tea, and coffee (without milk or sugar). You may also have popsicles or gelatin.

Your doctor may give you specific instructions about what to eat and drink before your colonoscopy. Be sure to follow these instructions carefully.
