What is a Low Residue Diet?
A low residue diet, sometimes called a low fiber diet, restricts foods that are high in fiber in order to ease gastrointestinal symptoms. It is often recommended for people with digestive diseases like inflammatory bowel diseases (IBD), diverticulitis, strictures, or bowel obstruction.
The goal is to avoid foods that could aggravate diarrhea, abdominal cramping, or gastrointestinal pain by reducing the amount of undigested material that passes through the digestive system.
How a Low Residue Diet Works
Fiber from plant foods like fruits, vegetables, whole grains, nuts, seeds, and legumes normally remain undigested until it reaches the colon. For people with gastrointestinal disorders, this excess fiber content can trigger increased bowel movements, loose stools or diarrhea which leads to:
- Loss of fluids and electrolytes
- Abdominal pain and cramping
- Fatigue and lethargy
- Malabsorption of nutrients
A low residue diet limits high fiber foods and instead focuses on well-cooked fruits and vegetables, along with low fiber grains that are easier to break down and digest. This helps decrease bowel movements and reduces irritation of the gastrointestinal tract.
Foods to Include on a Low Residue Diet Menu
If following a low residue diet for IBD, diverticulitis or another digestive disorder, the following foods are usually well tolerated:
Non-Whole Grains
Refined grains like white bread, pasta, crackers, couscous, white rice, corn or rice cereals, pancakes and waffles are permitted instead of high fiber whole grains.
Tender Fruits and Vegetables

Sample 1-Day Low Residue Diet Menu
Here is a sample menu with meal ideas to help guide your low residue diet meal planning:
Breakfast
- 1⁄2 grapefruit segments
- 1 scrambled egg

- Glass of lactose-free milk
Lunch
- Grilled chicken sandwich on white bread with lettuce, tomato

Drink plenty of water, juice, tea, or clear broths between meals to stay hydrated. Speak to your doctor or dietitian about taking vitamins/minerals if diet lacks variety long-term.
Tips for Transitioning to a Low Residue Diet
Making drastic changes to your diet too quickly can be challenging. Follow these tips to transition more smoothly:
Gradually Eliminate High Fiber Foods
Don’t remove ALL fiber at once, rather phase out insoluble fiber foods over several days while adding allowable options. This gives your body time to adjust.
Cook Produce Thoroughly
Properly cooking fruits and vegetables softens insoluble fiber making it gentler on your digestive tract. Steam, bake or sauté veggies rather than eating raw.
Try Low Fiber Substitutions
Swap out high fiber grains for white rice or bread. Choose bananas or melon over berries or salads. Consider meatballs rather than beans for plant-based protein.
Supplement with Soluble Fiber
Soluble fibers like oats, white rice bran, or psyllium may provide prebiotic benefits without irritating the bowel when inflamed. Discuss options with your physician.
A low residue diet can help provide symptom relief during flare-ups for people with gastrointestinal disorders. Work closely with a registered dietitian knowledgeable in IBD or diverticulitis nutrition to ensure your restricted diet still provides balanced nutrition.
FAQs
How long should you stay on a low residue diet?
In most cases, a low residue diet is only recommended short-term during a flare-up of symptoms from digestive conditions like IBD, diverticulitis or bowel obstruction. It helps provide relief from diarrhea, cramping and swelling. Long-term restriction should be monitored by a physician and dietitian.
What can I drink on a low residue diet?
Water, fruit juices without pulp, sports drinks, sodas, tea, and coffee are good low residue liquid options. Broths and clear soups also provide hydration without fiber. Limit alcohol which can irritate the digestive tract.
Is rice allowed on a low fiber diet?
Yes, white rice is permitted on a low residue diet. Brown or wild rice should be avoided since they contain more fiber. Well-cooked white rice is an easily digested source of carbohydrates.
Can I still get enough nutrition?
Work with a registered dietitian knowledgeable in GI disorders to ensure you meet nutritional needs. You may require extra proteins, fluids, vitamins and minerals while on a restricted fiber diet, especially if it is long term.
