A low-residue diet is supposed to put as many demands on the gastrointestinal system as possible. It’s quite similar to a low-fibre diet, but it also eliminates certain foods that can trigger bowel contractions.
A “residue” refers to a substance left in the digestive system after the initial stages of digestion are completed. These substances often comprise a lot of fibre as the system can’t fully digest fibre. This diet is usually suggested for people with inflammatory bowel disease (IBD) flares, for certain surgeries like bowel and colonoscopy prep, and for those with infectious colitis or acute diverticulitis.
What Is A Low Residue Diet?
A low-residue diet is a diet plan formulated to lessen the amount of undigested food that passes through the intestines. This type of diet is generally recommended for individuals who need to minimize bowel movements and decrease stool volume, such as those with inflammatory bowel disease (IBD), Crohn’s disease, ulcerative colitis, diverticulitis, or who are recovering from intestinal surgery.

How Does the Low Residue Diet Work?
The low-residue diet works by limiting foods that leave high indigestible material (residue) in the gastrointestinal tract. The primary goal is to reduce fibre intake, as it is a major component of residue. The diet decreases stool bulk and frequency by consuming low-fibre foods, giving the intestines time to heal and reducing irritation.
Health Benefits of a Low-Residue Diet
Reduces Bowel Movements
Helps manage symptoms of diarrhoea, abdominal cramping, and frequent bowel movements.
Eases Gastrointestinal Symptoms
Reducing the workload on the intestines can relieve discomfort associated with gastrointestinal disorders.
Facilitates Healing
Provides rest to the bowels, which is beneficial during flare-ups of IBD or after intestinal surgery.
Improves Nutrient Absorption
Minimizing the passage of undigested food may enhance nutrient absorption in individuals with digestive disorders.

Foods to Add and Avoid on a Low Residue Diet
Foods to Add:
Refined Grains: White bread, white rice, refined pasta, and low-fibre cereals.
Proteins: Tender, well-cooked meats (chicken, fish, turkey), eggs, and smooth nut butter.
Dairy: Milk, cheese, yogurt (without seeds or fruit pieces).
Vegetables: Cooked or canned vegetables devoid of seeds and skins, such as carrots, green beans, and potatoes (without skins).
Fruits: Fruit juices without pulp, canned or cooked fruits without skins or seeds (applesauce, peaches).

Foods to Avoid:
Whole Grains: Whole wheat bread, brown rice, oatmeal, and high-fibre cereals.
Raw Vegetables: Broccoli, cauliflower, Brussels sprouts, corn, and any raw vegetables.

Legumes: Beans, lentils, peas, and any foods made with these ingredients.
Nuts and Seeds: Whole nuts, seeds, and foods containing them.
High-Fibre Snacks: Popcorn, granola bars, and high-fibre snack bars.
Potential Side Effects of a Low Residue Diet
Nutrient Deficiencies: Limiting high-fibre foods can lead to micronutrient deficiencies such as vitamins, minerals, and antioxidants.
Constipation: A reduction in fibre intake can cause constipation in some individuals.
Bloating and Gas: Sudden changes in diet can lead to temporary digestive problems like bloating and gas.
Limited Food Choices: The diet can be restrictive and challenging to maintain over long periods, potentially leading to a monotonous diet and reduced enjoyment of food.
Weight Loss: Some people may unintentionally lose weight due to the restricted variety of foods and reduced caloric intake.
Conclusion
A low-residue diet can effectively manage symptoms of gastrointestinal disorders and support intestinal healing by reducing the amount of undigested food passing through the gut. While it offers significant benefits, particularly for those with conditions like IBD or recovering from surgery, it is essential to manage the diet carefully to avoid nutrient deficiencies and other potential side effects. It is always best to seek advice from a healthcare provider or registered dietitian before starting a low-residue diet to ensure it meets your health needs and nutritional requirements.
