A low residue diet is a medically prescribed eating plan that temporarily reduces the amount of undigested food (or “residue”) that passes through the colon. Often recommended in specific clinical scenarios, this diet can help ease symptoms, reduce bowel movements, and give the digestive tract time to heal. While the term “low residue” is often used interchangeably with “low fiber,” the two are not exactly the same. A low residue diet goes a step further by limiting not only fiber but also foods that stimulate bowel activity.
It’s important to note: this is a temporary medical diet, not a long-term lifestyle plan. It’s typically followed under the guidance of a healthcare provider for a set period of time and tailored to the individual’s condition and goals.
Why Is a Low Residue Diet Prescribed?
A low residue diet is often recommended to:
● Prepare for a colonoscopy or other gastrointestinal procedure
● Manage symptoms of Crohn’s disease, ulcerative colitis, or diverticulitis during flare-ups
● Help recovery after bowel surgery or during a bowel rest period
● Treat or manage intestinal strictures, radiation enteritis, or other forms of bowel obstruction
● Reduce diarrhea, abdominal cramping, and bloating
The goal is to minimize the workload on your digestive tract by limiting foods that leave undigested material behind.
What Foods Are Included in a Low Residue Diet Menu?
A low residue diet includes easily digestible foods that produce minimal stool. These foods are typically low in fiber, fat, and spice.
Approved Foods:
Grains & Breads
- White bread, white rice, and plain pasta
- Low-fiber cereals (e.g., puffed rice, cornflakes)
- Plain crackers or melba toast
Protein
- Tender, well-cooked meat, poultry, or fish
- Eggs (boiled, poached, or scrambled)
- Tofu or smooth nut butters in small amounts
Dairy
- Milk, yogurt, and cheese in moderation (unless otherwise advised)
Fruits
- Canned or cooked fruits without seeds or skins (e.g., applesauce, canned peaches)
- Ripe bananas
Vegetables
- Well-cooked, skinless vegetables like carrots, zucchini, or green beans
- Strained vegetable juices
Desserts & Snacks
- Plain cookies, gelatin, sherbet, or vanilla pudding
- Sugar, honey, and plain hard candies
Beverages
- Water, broth, tea, and electrolyte drinks
- Decaffeinated coffee or clear juices without pulp
Foods to Avoid on a Low Residue Diet:
- Whole grains, brown rice, seeds, nuts, and popcorn
- Raw fruits and vegetables, especially those with skins or seeds
- Legumes like beans, peas, and lentils
- Tough or fatty cuts of meat
- Fried or heavily spiced foods
- Caffeinated beverages and alcohol
These foods can increase bowel activity, cause irritation, or add unwanted bulk to stool during the healing or preparation phase.
How Long Should You Follow a Low Residue Diet?
The low residue diet is not meant for long-term use. While it can provide relief and promote healing in the short term, long-term restriction of fiber and certain nutrients can lead to nutritional deficiencies. Your doctor or dietitian will provide guidance on how long to follow this diet and how to safely reintroduce higher-fiber foods.

Conclusion
A low residue diet can play a vital role in managing digestive symptoms, preparing for procedures, or supporting recovery. While it’s a helpful short-term medical tool, it is not a substitute for a balanced, long-term eating plan. Always work with your healthcare provider or a registered dietitian to ensure you’re meeting your nutritional needs—both during and after the diet.
