Low-fiber dietBy Mayo Clinic Staff
Fiber is the part of fruits, vegetables and grains not digested by your body. A low-fiber diet restricts these foods. As a result, the amount of undigested material passing through your large intestine is limited and stool bulk is lessened.
A low-fiber diet may be recommended for a number of conditions or situations. It is sometimes called a restricted-fiber diet.
Your doctor may prescribe a low-fiber diet if:
- You have narrowing of the bowel due to a tumor or an inflammatory disease
- You have had bowel surgery
- You are having treatment, such as radiation, that damages or irritates your digestive tract
As your digestive system returns to normal, you usually can slowly add more fiber back into your diet.
A low-fiber diet limits the types of vegetables, fruits and grains that you can eat. Occasionally, your doctor may also want you to limit the amount of milk and milk products in your diet. Milk doesn't contain fiber, but it may contribute to discomfort or diarrhea.
The ability to digest food varies from person to person. Depending on your condition and tolerance, your doctor may recommend a diet that is more or less restricted.
If you're eating a low-fiber diet, be sure to read food labels. Foods you might not expect — such as yogurt, ice cream, cereal and even beverages — can have added fiber. Look for foods that have no more than 1 gram of fiber in a serving.
Foods that are generally allowed on a low-fiber diet include:
- White bread without nuts and seeds
- White rice, plain white pasta, and crackers
- Refined hot cereals, such as Cream of Wheat, or cold cereals with less than 1 gram of fiber per serving
- Pancakes or waffles made from white refined flour
- Most canned or well-cooked vegetables and fruits without skins or seeds
- Fruit and vegetable juice with little or no pulp, fruit-flavored drinks, and flavored waters
- Tender meat, poultry, fish, eggs and tofu
- Milk and foods made from milk — such as yogurt, pudding, ice cream, cheeses and sour cream — if tolerated
- Butter, margarine, oils and salad dressings without seeds
You should avoid:
- Whole-wheat or whole-grain breads, cereals and pasta
- Brown or wild rice and other whole grains, such as oats, kasha, barley and quinoa
- Dried fruits and prune juice
- Raw fruit, including those with seeds, skin or membranes, such as berries
- Raw or undercooked vegetables, including corn
- Dried beans, peas and lentils
- Seeds and nuts and foods containing them, including peanut butter and other nut butters
If you're eating a low-fiber diet, a typical menu might look like this.
1 glass milk, if tolerated
1 slice of white toast with smooth jelly
1/2 cup canned peaches
1 cup of yogurt if tolerated, without seeds or nuts
1 to 2 cups of chicken noodle soup
Sandwich of drained tuna with mayonnaise on white bread
Flavored water or iced tea
White toast, bread or crackers
2 slices of cheese or 1/2 cup cottage cheese, if tolerated
3 ounces lean meat, poultry or fish
1/2 cup white rice
1/2 cup cooked vegetables, such as carrots or green beans
White dinner roll with butter
Prepare all foods so that they're tender. Good cooking methods include simmering, poaching, stewing, steaming and braising. Baking or microwaving in a covered dish is another option.
Try to avoid roasting, broiling and grilling — methods that tend to make foods dry and tough. You may also want to avoid fried foods and spices.
Keep in mind that you may have fewer bowel movements and smaller stools while you're following a low-fiber diet. To avoid constipation, you may need to drink extra fluids. Drink plenty of water unless your doctor tells you otherwise.
