    Colonoscopy Preparation Drink & Food Recipes

    You are getting ready for a colonoscopy and you are overwhelmed with the idea of having to cleanse your bowels the day before the surgery. Then, your physician hands you a list of foods you cannot eat several days before the procedure. But just because you have to follow a restricted diet does not mean you have to eat bland flavorless foods the week before your procedure. 

    There are several reasons your physician is asking you to follow these restrictions before your procedure. High-fiber, high-fat, and complex protein foods take time to digest and may reside in the colon for several days if not adequately processed. These residual fibers are difficult to flush out of the system, even with the laxatives you are given the day before the procedure. Inadequate bowel preparation can have the following consequences:

    • Increases difficulty and level of complexity of colonoscopy
    • Extends time of the  procedure
    • Inhibits the ability of your gastroenterologist to visualize the colon
    • Patients will need to repeat procedure 
    • Shortens the interval time between the next screening colonoscopy 
    • Reduces the ability of gastroenterologist to identify polyps and abnormalities

    Five days before your colonoscopy your physician will ask you to avoid high-fiber foods and restrict your diet to proteins and foods that are easily digestible, well-cooked, tender, and peeled. In addition, there may be other restrictions to your diet which often include avoiding the following:

    • Prunes or prune juice
    • Raw or dried fruit
    • All berries, figs, dates, and raisins, 
    • Whole grains, including brown or wild rice, buckwheat, and cornbread
    • Any food that contains seeds or nuts
    • Dry beans, peas, lentils, and tofu
    • Tough, fibrous meat with gristle
    • Popcorn
    • Pickles, olives, horseradish, and relish
    • Coconut
    • Jam, marmalade, or preserves (especially with seeds)
    • No red or purple (food dye) colored drinks or foods

    In addition, one day prior to your procedure you will be asked to cleanse your bowels and be on a clear liquid diet, with no exceptions. It is highly important you follow the directions ordered by your physician to be sure no food or fibers are left in the colon which can restrict the visualization of your intestinal lining. 

    With some meal planning and a trip to the grocery store, you will be able to prepare and eat meals that are flavorful and healthy and will not cause any problems during your colonoscopy. In this article, you will find that there are quite a few food options and recipes available to you and the preparation does not have to be a bland and tasteless dining experience. 

    The following shopping list and recipe suggestions are for reference use only. Be sure to check with your physician to be sure that what you eat or drink before your colonoscopy does not interfere with any medications or the procedure itself.
