A low-fiber diet is a temporary eating plan designed to help minimize symptoms associated with various digestive issues, such as inflammatory bowel disease (IBD) flares, diverticulitis, or to prepare for certain medical procedures like a colonoscopy. Unlike a high-fiber diet, which is typically recommended for general health, this approach limits fiber intake to give the bowels a rest. A low-fiber diet typically restricts daily fiber intake to between 10 and 15 grams.
Appropriate Grains and Starches
When on a low-fiber diet, the focus shifts to refined grains, which have had most of their fiber-rich components removed during processing. These are easier for the body to digest and leave minimal residue in the intestines.
Suitable Grain Choices
- White Bread and Rolls: Look for products made with white or refined flour.
- Refined Pasta and Noodles: White pasta, macaroni, and rice noodles are good options.
- White Rice: This is a staple of many low-fiber diets.
- Low-Fiber Cereals: Options include Corn Flakes®, Rice Krispies®, Cream of Wheat®, or Cream of Rice®.
- Plain Crackers: Saltine crackers and other plain, refined crackers are acceptable.
Allowed Fruits and Vegetables
For fruits and vegetables, careful preparation is the most important factor. The goal is to remove all skins, seeds, and tough fibrous parts that are difficult to digest.
Cooked and Canned Vegetables
- Peeled Potatoes: White, sweet, or red potatoes are fine, as long as the skins are removed.
- Well-Cooked Carrots and Asparagus: Ensure they are cooked until tender.
- Cooked Green Beans and Wax Beans: These are often well-tolerated.
- Strained Vegetable Juices: Opt for juices without any pulp.
Tolerated Fruits
- Ripe Bananas and Melons: Cantaloupe, honeydew, and seedless watermelon are soft and easy to digest.
- Applesauce and Canned Peaches: Choose canned varieties packed in juice, not heavy syrup, and ensure there are no skins.
- Pulp-Free Fruit Juice: Clear fruit juices like apple or white grape juice are acceptable.
Protein Sources for a Low-Fiber Diet
Lean, tender proteins are generally well-tolerated and provide essential nutrients without adding significant fiber or residue. Cooking methods should also be gentle, such as baking, poaching, or stewing.
Recommended Proteins
- Tender Meat and Poultry: Well-cooked, tender beef, chicken, turkey, lamb, and pork without gristle or skin.
- Fish and Eggs: Cooked fish (baked, broiled) and eggs are excellent, low-residue options.
- Smooth Peanut Butter and Tofu: Smooth nut butters contain less fiber than chunky varieties, and tofu is a versatile protein choice.
- Dairy: Plain milk, yogurt, and cheese are fine if you are not lactose intolerant.
Other Accepted Foods
Beyond the main food groups, several other items can be included in a low-fiber eating plan.
Additional Low-Residue Items
- Smooth Sauces: Plain tomato sauce (strained, no seeds), plain gravies.
- Clear Soups and Broths: Strained soups are ideal.
- Simple Desserts: Plain gelatin, custard, pudding, ice cream, sherbet, plain cakes, and cookies without nuts or fruit.
- Condiments and Fats: Butter, margarine, oils, mayonnaise, and smooth dressings are acceptable.
High-Fiber Foods to Avoid
To ensure the diet's effectiveness, it is crucial to avoid high-fiber foods that can irritate the digestive system. This includes:
- Whole-wheat and whole-grain breads, pastas, and cereals
- Brown rice, wild rice, and quinoa
- Nuts, seeds, and crunchy nut butters
- Dried fruits, such as prunes, raisins, and dates
- Beans, lentils, and peas
- Raw or unpeeled vegetables and fruits, including berries
- Popcorn
- Coconut

Key Low-Fiber Diet Tips
To maximize the benefits of a low-fiber diet, consider the following suggestions:
- Drink Plenty of Fluids: Aim for 8-10 glasses of non-caffeinated liquids per day to prevent dehydration and constipation.
- Eat Smaller, More Frequent Meals: This can be easier for your digestive system to handle than three large meals.
- Chew Your Food Thoroughly: This helps break down food particles, aiding digestion.
- Avoid Spicy and Fatty Foods: Foods that are very spicy or fried can irritate the gut and worsen symptoms.
- Check Labels Carefully: Many packaged foods can have unexpected added fiber. Look for products with less than 1-2 grams of fiber per serving.
Conclusion
Knowing what can I eat while on a low-fiber diet is the first step toward managing digestive discomfort and allowing your bowels to rest. By focusing on refined grains, tender proteins, and carefully prepared fruits and vegetables, you can create a menu that is both nutritious and effective. Remember that this diet is often temporary and should be followed under the guidance of a healthcare professional or registered dietitian, who can advise when and how to reintroduce fiber back into your diet. Always consult your doctor before beginning a low-fiber eating plan to ensure it is appropriate for your specific health needs.
