Why Diet Matters Before a Colonoscopy

In the days leading up to a colonoscopy, patients must follow a restricted diet. This is done to adequately clear out and cleanse the colon prior to the procedure.

The main goals of a pre-colonoscopy diet are:

  • Reduce fiber intake – Fiber can leave residue in the colon and obstruct visibility

  • Avoid foods that may mimic abnormalities – Such as red liquids or foods that could be mistaken for blood.

  • Stick to easily digestible foods – To limit stool bulk and residue.

  • Help the bowel prep work effectively – Restricted diet improves laxative results.

Following your doctor’s dietary instructions is crucial to having a successful colonoscopy. Failing to restrict your diet properly can result in poor visibility and may require repeating the procedure.

Foods to Avoid Before Your Colonoscopy

Here are the main categories of foods to avoid leading up to your colonoscopy:

  • High-fiber foods: Raw fruits and veggies, skins, seeds, corn, dried fruit, nuts, whole grains.

  • Fatty and fried foods: These can be difficult to digest and leave residue. Avoid greasy and fried items.

  • Tough and chewy foods: Avoid tough, fibrous meats with gristle. Opt for soft, well-cooked proteins.

  • Deli meats and sausages: High sodium and fat content can interfere with the colonoscopy.

  • Popcorn: Can leave hard-to-digest kernels.

  • Red and purple liquids: Sports drinks, juices, sodas with red or purple dye.

Sticking to a low-fiber diet of cooked fruits and vegetables, white breads, and tender meats can help prepare the colon.

Allowed Foods for a Pre-Colonoscopy Diet

Fruits and Juices: Canned or cooked fruits without skins or seeds. Apple, white grape, or orange juice without pulp.

Vegetables: Well-cooked, canned, or strained vegetables without skins or seeds. Potatoes without skin, for example.

Protein: Tender, well-cooked poultry, fish, eggs, pork, or beef. Bacon is also permitted.

Dairy: Milk, plain yogurt, cheese, butter.

Be sure to choose items that are low in fiber and easy to digest.

Why Lean Protein Like Bacon is Allowed

In the days prior to your colonoscopy, protein foods like bacon, poultry, and fish are permitted. Here’s why:

  • Protein doesn’t have the fibrous quality or seeds that can clog the colon.

  • Bacon and other proteins keep you feeling fuller compared to a diet of justjuice and Jell-O.

  • Protein helps retain muscle during short-term dieting.

However, it’s important to choose leaner proteins. Avoid high-fat sausages, bologna, and pepperoni. Opt for low-fat proteins like turkey bacon, chicken, or fish. Well-cooked bacon is permissible but should be eaten in moderation.

Breakfast: Scrambled eggs, white toast with butter, apple juice.

Lunch: Baked chicken breast, white rice, cooked carrots, canned peaches.

Dinner: Grilled salmon, mashed potatoes, cooked green beans.

Focus on gentle proteins, low-fiber grains, and cooked fruits and vegetables.

Tips to Follow the Diet More Easily

Sticking to a limited pre-colonoscopy diet can be challenging. Here are some tips to make it easier:

  • Clear out high-fiber foods from your kitchen so you aren’t tempted.

  • Pick up allowed foods like chicken broth, white bread, and apple juice so you have diet-appropriate items on hand.

  • Cook fruits and vegetables thoroughly until very soft to reduce fiber.

  • Choose tender, well-cooked proteins like scrambled eggs, canned tuna, or bacon.

  • Drink fluids between meals if feeling hungry. Broth, juice, or clear soda can help.

  • Consider a low-fiber diet for a few days prior to restrict fiber gradually.

  • Discuss anti-nausea medication if bowel prep makes you vomiting.

Careful meal planning and preparation can help you successfully stick to the necessary dietary restrictions before your colonoscopy.

The Bottom Line
