What should you eat the day before a colonoscopy?

ANSWER

The day before your procedure you can’t eat anything solid. Stay hydrated by drinking lots of clear liquids, such as sports drinks, clear juice like apple and white grape, and broth. Soda is okay, and so are coffee and tea, but without cream. You can have gelatin and ice pops, but stay away from anything colored red, blue, or purple. The dyes can discolor the lining of the colon and make it harder for the doctor to see. Also avoid alcohol and drinks you can’t see through, like milk or orange juice.

Two hours before the procedure, be sure not to drink or eat anything.
