Understanding a Low Residue Diet: Essentials and Medical Purpose
What Is a Low Residue Diet?
A low residue diet reduces the amount of undigested food moving through the intestines. “Residue” means fiber and other substances that remain after digestion. The main goal of a low residue diet is to allow the digestive system to rest and heal, especially during certain medical conditions. It is not a weight-loss diet, but a special nutrition plan meant to lower stool production and irritation in the gut.
Who Needs a Low Residue Diet? Indications and Guidance
Doctors may recommend a low residue diet if you have:
- Inflammatory bowel diseases (like Crohn’s or ulcerative colitis), especially during flare-ups
- Diverticulitis
- Bowel surgery recovery
- Bowel preparation before medical tests, such as a colonoscopy
- Other gut problems needing less irritation or lower stool volume
You should only follow a low residue diet under medical advice and for a limited time. Always check with your doctor or dietitian for personalized guidance.
The Science: How a Low Residue Diet Supports Digestive Health
Residue is mostly made up of fiber, which is found in whole grains, many fruits, vegetables, and some nuts and seeds. While fiber is healthy for most people, it can be harsh on a sensitive gut. A low residue diet limits foods with lots of fiber. This can help reduce diarrhea, gas, bloating, and pain by slowing down bowel movements, making stools softer and easier to pass.
What Foods Are on a Low Residue Diet? Allowed and Restricted Lists (2026 Update)
Allowed Foods: Grains, Proteins, Dairy, Fruits, and Vegetables
Here are foods you can enjoy on a low residue diet:
- Refined grains: White bread, plain bagels, white rice, plain pasta, pancakes (made with white flour)

- Dairy: Milk, yogurt (without fruit pieces), butter, cheese in small amounts

Restricted Foods: What to Avoid and Why
You should avoid these foods on a low residue diet:
