Low Residue Diet

A low residue diet is often recommended after surgery or during a flare-up of diverticulitis and acute stages of colitis. A low residue diet may also be recommended prior to a colonoscopy.  Low residue foods help to decrease fecal output or the number of bowel movements per day. A low-residue diet may be used for a short time before transition to a low-fiber or regular diet.

The terms "fiber" and "residue" are sometimes used interchangeably. But technically, they're not the same thing. Fiber is the undigested part of plants that remains in the intestinal tract and contributes to stool. Residue includes fiber and any other foods that may increase stool output.

A low-residue diet is similar to - but more restrictive than - a low-fiber diet. A low residue diet can be adequate in all necessary nutrients with the guidance of a dietician.

Foods allowed:

  • Refined breads, cereals, crackers, chips and pasta with less than 1 gram of fiber per serving (Note: Ideally, look for products with zero grams of dietary fiber per serving.)
  • White rice
  • Vegetable juices without seeds or pulp
  • Fruit juices with no pulp
  • No more than 2 cups a day of milk, yogurt, pudding, ice cream, and cream-based soups and sauces (strained)
  • Tender meat, poultry, fish and eggs
  • Oil, margarine, butter and mayonnaise
  • Smooth salad dressings
  • Broth-based soups (strained)
  • Jelly, honey and syrup

Foods to avoid:

  • Whole-grain breads, cereals and pasta
  • Whole vegetables and vegetable sauces
  • Whole fruits, including canned fruits
