Ostomy Diet: What to Eat and What to Avoid

Food lists can make eating with an ostomy sound like a collection of permanent bans. It isn’t. Ask one question first: “Is this advice for the first weeks after surgery, or for my everyday life now?” Then look at the portion, the preparation and how you respond.

Most people with an ostomy go back to a varied, everyday diet.

Quick answer

There is no single lifelong ostomy diet. Your stage of recovery, the type of stoma and your own tolerance matter. A temporary lower-fiber plan may be part of recovery after bowel surgery; long-term eating is usually more varied. With an ileostomy, pay particular attention to your individual fluid and salt plan.

Easier at the start

White rice and pasta
Eggs
Tender chicken and fish
Mashed potato, no skin
Ripe banana, applesauce
White toast and crackers
Yogurt and mild cheese
Peeled, well-cooked vegetables
Broth and smooth soups

With a new ileostomy, go slow with

Corn and popcorn
Fruit and vegetable skins
Seeds and nuts
Raw lettuce and salad
Whole-wheat bread
Beans and lentils, if not well chewed
Dried fruit and coconut
Mushrooms and celery

“Go slow” means later, smaller, cooked and well chewed, not never. Your discharge plan comes first. Looking for one food? Use the food checker.

Start with your type of ostomy and stage of recovery

The right plate looks different six days after surgery than it does six months after. And an ileostomy and a colostomy behave differently, because they sit at different points of the bowel.

What deserves attention, by type of ostomy
Your situation	What deserves attention	A useful question for your team
New ileostomy	Food texture, temporary fiber limits and replacing fluid losses.	What should I eat now, and when should I start adding foods back?
Established ileostomy	Your usual output, hydration and individual food tolerance.	What change in my output or urine should prompt a call?
Colostomy	Regular meals and how foods affect your own stool pattern. Output is usually more formed than with an ileostomy, and you lose less fluid, because the colon has already absorbed much of the water.	Do I need any restrictions for my particular operation?
High output or another condition	A coordinated plan for fluids, food and any relevant medicines.	Who should I contact if I cannot keep up with losses or eat enough?

For the anatomy behind these differences, read ileostomy vs colostomy. The amount and part of bowel remaining can matter as much as the name of the stoma. A urostomy has different considerations because it diverts urine rather than stool. If you have a colostomy, our colostomy diet guide goes deeper; with an ileostomy, see the ileostomy diet guide.

Eating in the first weeks after surgery

Memorial Sloan Kettering's ileostomy guidance describes small, regular meals, careful chewing and mostly bland, low-fiber foods during the early recovery period. New foods are introduced individually as tolerance develops. Follow the timing given by your own team rather than copying someone else's recovery schedule.

Ostomy diet in the first weeks: woman stirring a soft meal in a pan in her kitchen, beige SIIL wrap at her waist — Soft, simple and small: the first weeks are about easy food, not a perfect menu.

In hospital and the first days home
Fluids first, then small, soft, low-fiber meals. Eating little and often is easier than three big plates.
The first weeks
Keep to the foods your discharge sheet lists. Chew every mouthful well, sit up to eat and drink between meals as well as with them.
When your team says it's time
Add one new food at a time, in a small portion, and wait a day before the next one. If something disagrees with you, park it and try again in a few weeks.
Everyday life
Most people end up eating a varied, normal diet, with a short personal list of foods they chew extra well or keep small.

Examples to discuss include eggs, tender fish or chicken, white rice or pasta, and appropriately prepared peeled or cooked produce. A “soft” food is not necessarily low in fiber: seeds and skins still matter. If your discharge sheet and an online food list disagree, ask your team to clarify the difference.

Not a prescription, just a picture of what “small, soft and often” can look like on a plate. Swap anything your own plan doesn't include.

BreakfastScrambled egg, white toast with butter, half a ripe banana
Mid-morningPlain yogurt or a few saltines, plus a drink
LunchChicken and white rice, peeled cooked carrots
AfternoonSmooth peanut butter on crackers, or applesauce
DinnerBaked fish, mashed potato without skin, soft-cooked squash

Can I eat it? Check a food in seconds

Pizza, curry, baked beans, strawberries, chocolate: these are the foods people ask about most. Search below, or filter by status. Each card tells you how the food usually fits in the early weeks, especially with a new ileostomy, and how it usually fits later on.

Search a food

White rice
Usually easy early on
Early weeks: One of the easiest starters. Plain or with a little butter or broth.
Later on: Brown and wild rice have more fiber: bring them back slowly.
Pasta and noodles
Usually easy early on
Early weeks: White pasta is a classic early food. Keep sauces mild.
Later on: Whole-wheat pasta has more fiber; try a small portion first.
Eggs
Usually easy early on
Early weeks: Scrambled, boiled or poached are soft and full of protein.
Later on: Most people keep eating eggs every week. Some notice more odor.
Chicken, turkey and fish
Usually easy early on
Early weeks: Tender, moist and well chewed. Baked or poached is easier than fried.
Later on: Tough or gristly cuts need extra chewing.
Potatoes
Usually easy early on
Early weeks: Mashed or baked without the skin is a good early choice.
Later on: The skin is fiber: add it back in small amounts.
Bananas
Usually easy early on
Early weeks: Ripe bananas are soft and can help thicken loose output.
Later on: Still a useful food on looser days.
Applesauce
Usually easy early on
Early weeks: Smooth, easy, and often used to thicken output.
Later on: Raw apple with skin needs more chewing.
White bread and crackers
Usually easy early on
Early weeks: Toast, saltines and plain pretzels are easy and help some people with loose output.
Later on: Seeded and whole-grain breads come back gradually.
Oatmeal
Small test portions
Early weeks: Smooth cooked oats are often fine. Start with a small bowl.
Later on: Many people eat oatmeal daily. Add nuts and dried fruit last.
Yogurt and cheese
Usually easy early on
Early weeks: Plain yogurt and mild cheese are easy protein, if dairy agrees with you.
Later on: Watch your own pattern: lactose bothers some people.
Milk and ice cream
Small test portions
Early weeks: Fine for many, but lactose can loosen output or add gas for some.
Later on: Lactose-free versions are an easy swap if needed.
Smooth peanut butter
Usually easy early on
Early weeks: Smooth (not crunchy) is a handy protein and can thicken output.
Later on: Crunchy peanut butter has nut pieces: chew well.
Pizza
Small test portions
Early weeks: A slice of plain cheese pizza on a thin crust is a reasonable test once you are eating normally.
Later on: Toppings decide it: mushrooms, corn, olives and peppers are the ones to chew well.
Curry and spicy food
Small test portions
Early weeks: Mild and in a small portion. Spice can loosen output in some people.
Later on: Many people enjoy curry again. Build up the heat gradually.
Baked beans and lentils
Usually wait at first
Early weeks: Pulses add gas and fiber. Most plans wait, then start with a few spoonfuls.
Later on: Smooth hummus and well-cooked lentils are often easier than whole beans.
Weetabix and bran cereals
Usually wait at first
Early weeks: Whole-grain and bran cereals are high in fiber. Usually after the low-fiber phase.
Later on: Try half a portion with plenty of milk or fluid.
Whole-wheat bread
Usually wait at first
Early weeks: More fiber than white bread. Often brought back after the first weeks.
Later on: Seeded loaves last; chew thoroughly.
Strawberries
Small test portions
Early weeks: Tiny seeds and fiber. Small portions once your team allows fruit.
Later on: Many people eat them again; blending into a smoothie helps.
Raspberries and blackberries
Usually wait at first
Early weeks: Lots of seeds. Usually wait during a low-fiber phase.
Later on: Strain them, blend them, or test a few at a time.
Blueberries
Small test portions
Early weeks: Softer skins than most berries. Start with a small handful.
Later on: Usually fine for most people.
Grapes
Small test portions
Early weeks: Skins are the issue: peel or skip them at first.
Later on: Chew well; seedless are easier.
Apples and pears
Small test portions
Early weeks: Peeled and cooked is easier than raw with the skin.
Later on: Raw with skin comes back slowly.
Oranges and pineapple
Usually wait at first
Early weeks: Stringy membranes and fibers. Juice without pulp is easier at first.
Later on: Small portions, chewed well. Pineapple is a common blockage culprit.
Dried fruit
Usually wait at first
Early weeks: Dried fruit swells and is a common blockage culprit with an ileostomy.
Later on: Small amounts, well chewed, with plenty of fluid.
Avocado
Usually easy early on
Early weeks: Soft and smooth. Usually easy in small portions.
Later on: A good everyday fat for most people.
Cooked carrots and squash
Usually easy early on
Early weeks: Peeled and cooked until soft are some of the easiest vegetables.
Later on: Keep enjoying them; add raw versions slowly.
Sweet potato and eggplant
Small test portions
Early weeks: Peeled and well cooked can fit many lower-fiber plans.
Later on: Tough skins come back last.
Broccoli and cauliflower
Small test portions
Early weeks: Soft-cooked florets in small portions. They can add gas.
Later on: Not banned, just gassy for some people.
Cabbage, kale and Brussels sprouts
Usually wait at first
Early weeks: Fibrous and gassy. Usually later, cooked soft.
Later on: Raw coleslaw and kale salads come back last.
Lettuce and raw salad
Usually wait at first
Early weeks: Raw leaves are hard to break down early with an ileostomy.
Later on: Shred finely, start small, chew well.
Tomatoes
Small test portions
Early weeks: Sauce and peeled, seeded tomato are easier than raw skins.
Later on: Raw tomato is usually fine in small amounts later.
Cucumber and celery
Usually wait at first
Early weeks: Skins, seeds and strings. Celery is a known blockage culprit.
Later on: Peel cucumber; chop celery very finely.
Onions and garlic
Small test portions
Early weeks: Cooked in small amounts. Raw onion adds gas and odor for many.
Later on: Most people use them in cooking without trouble.
Mushrooms
Usually wait at first
Early weeks: Rubbery texture. A common blockage culprit with an ileostomy.
Later on: Chop small and chew very well.
Corn and popcorn
Usually wait at first
Early weeks: Kernels pass whole. One of the classic foods to wait on.
Later on: Creamed corn or a small portion, chewed thoroughly. Popcorn last.
Peas and green beans
Small test portions
Early weeks: Soft-cooked and mashed in small portions.
Later on: Peas add gas for some people.
Nuts and seeds
Usually wait at first
Early weeks: Hard pieces. Usually wait, especially with a new ileostomy.
Later on: Small portions, chewed to a paste, or swap for nut butters.
Coconut
Usually wait at first
Early weeks: Fibrous flakes are a known blockage culprit.
Later on: Coconut milk is easier than flakes.
Olives
Small test portions
Early weeks: Pitted and chewed well, in small amounts.
Later on: Usually fine for most people.
Chocolate
Small test portions
Early weeks: A small piece is fine for most. Larger amounts can loosen output.
Later on: Watch your own pattern with rich desserts.
Coffee and tea
Small test portions
Early weeks: Caffeine can speed up output. Start with one cup and see.
Later on: Most people drink coffee again. Count it alongside your other fluids.
Soda and sparkling water
Small test portions
Early weeks: Bubbles mean gas in the pouch. Let it go flat or sip slowly.
Later on: A small glass is fine for most; skip the straw.
Alcohol
Small test portions
Early weeks: Ask your team first. Alcohol dehydrates, and beer adds gas.
Later on: Drink water alongside, especially with an ileostomy.
Fruit juice
Small test portions
Early weeks: Pulp-free and in small amounts. Some juices loosen output.
Later on: Water down or mix with a rehydration drink if your team suggests.
Bone broth and soup
Usually easy early on
Early weeks: Warm, salty and easy. Useful for fluids and salt with an ileostomy.
Later on: Chunky soups: check what is in them.
Fried and greasy food
Small test portions
Early weeks: Rich, fatty meals can loosen output. Keep portions small.
Later on: An occasional treat for most people.
Sausage, hot dogs and deli meat

Small test portions
Early weeks: Sugar alcohols can loosen output; gum makes you swallow air.
Later on: Read labels for sorbitol and similar sweeteners.
Marshmallows and smooth desserts
Usually easy early on
Early weeks: Marshmallows, pudding and gelatin are soft; some people use marshmallows to thicken output.
Later on: Fine as an everyday treat.

Based on low-fiber and stoma diet guidance from Cambridge University Hospitals, MSK and UOAA. Everyone's tolerance is different; your own team's list comes first.

What to eat, limit or reintroduce: a practical way to decide

Instead of labeling a whole food group “good” or “bad,” use the questions below. This is a planning tool, not a list of foods guaranteed to suit everyone.

Five questions that make a food decision useful
Food or meal	What to check	How to make the decision useful
Vegetables and fruit	Skins, seeds, stringy texture, raw versus cooked.	Check your current plan and record the preparation, not just “vegetables.”
Bread, rice and cereal	Whole grains, bran, nuts or seeds added to the product.	Read the label; similar-looking products may have different ingredients.
Milk and dairy	Your own tolerance and whether symptoms repeat.	Do not remove the entire group after one uncomfortable meal.
A restaurant meal	Ingredients, portion size and unfamiliar sauces.	Ask for a sauce separately if that makes the meal easier to assess.
A food you want to bring back	Whether your team has cleared reintroduction.	Try one change at a time so you can tell what happened.

Foods most often linked to a blockage with an ileostomy

Popcorn, corn, nuts, coconut, dried fruit, celery, mushrooms, pineapple, and fruit and vegetable skins. They are not forbidden forever: they are the ones to cut small, chew to a paste, eat in small portions and drink with. Cramping with little or no output is a reason to call your team; our stoma blockage guide explains the signs.

Hydration with an ileostomy: get an individual plan

An ileostomy can increase losses of water and salts. MedlinePlus advises discussing fluid needs with your healthcare provider and watching for dehydration. Do not rely on a single internet target for everyone, especially if you have high output, kidney or heart problems, or a prescribed fluid restriction.

Hydration with an ileostomy: man drinking a glass of water at his home desk, navy SIIL ostomy belt at his waist — Sipping through the day is easier than catching up at night.

Ask your team what your usual output should look like, whether you need to measure it, what to drink and when to call. Oral rehydration solutions may be part of an individualized plan. Sports drinks, plain water and oral rehydration solutions are not automatically interchangeable.

Everyday habits that help

Sip through the day instead of large amounts at once
Keep a bottle where you work, drive and sleep
Pale yellow urine is a simple daily check
Salty foods like broth and crackers can be part of the plan

Get prompt advice if you notice

Markedly reduced or dark urine
Dizziness, cramps or persistent thirst
A sudden change in output
Watery output you can't keep up with

Severe abdominal pain, vomiting or a swollen abdomen with little or no output can be signs of obstruction and require urgent assessment. Do not try to solve those symptoms with a food experiment. If your output is often very watery, our guide to high-output ileostomy covers what teams usually check.

References: MedlinePlus: Ileostomy and your diet; UOAA: Diet and nutrition.

Gas, odor and output: look for your own pattern

Some foods and drinks affect gas or stool consistency, but the effect is not identical for everyone. UOAA emphasizes individual tolerance rather than a single “ostomy diet.” Chewing well and introducing foods thoughtfully are more useful habits than copying a long list of restrictions forever.

Four common examples of foods that add gas for many people. Not a list of bans: just the first places to look if your pouch fills with air.

Fizzy drinksSoda, sparkling water and beer. Let them go flat, or sip without a straw.
Beans and lentilsBaked beans, chickpeas and lentils. Start with a few spoonfuls.
CabbageAnd its family: broccoli, cauliflower, Brussels sprouts. Cooked soft, small portions.
OnionsRaw onion more than cooked. Also a common cause of stronger odor.

Ostomy diet and social life: woman passing a bowl of pasta at a backyard dinner with friends, black SIIL wrap at her waist — Knowing your own pattern is what makes a dinner invitation easy to say yes to.

Foods that may thicken output

Ripe bananas and applesauce
White rice, pasta and potatoes
Smooth peanut butter, cheese
Oatmeal, marshmallows, saltines

Foods that may loosen output

Spicy and very fatty meals
Alcohol and lots of caffeine
Some juices and raw fruit
Sugar-free sweets with sorbitol

If you notice a problem, write down the meal, portion, preparation and timing. Consider the whole situation: a large unfamiliar meal eaten quickly is different from a small portion of one food. If odor occurs while your pouch is closed, check the pouching system with your nurse rather than assuming diet is the only explanation. More in our guide to ostomy odor and to pancaking.

A simple food diary you can actually use

SIIL Ostomy · Food diary

Meal: what you ate and roughly how much.
Preparation: raw, peeled, cooked, fried, with seeds or with sauce.
What changed: gas, discomfort, output consistency or nothing unusual.
Other context: a new medicine, illness, a very hot day or an unfamiliar routine.
Question to ask: one specific point for your nurse or dietitian.

Print it and fill in a few days
Day and time	Meal and portion	Preparation	What changed

Keeping an ostomy food diary: woman writing a note at her kitchen island next to a bowl of oatmeal, beige SIIL ostomy belt at her waist — Two lines a day are enough to spot your own pattern.

The diary is there to make a conversation easier, not to make every meal feel like an exam. If you keep restricting more foods or are losing weight unintentionally, ask for dietitian support.

Meals away from home and clothes that feel comfortable

For an early meal out, choose a place where you can ask about ingredients and order something familiar. Give yourself time, bring the supplies you normally need and avoid making the occasion a test of several new foods at once.

Eating out with an ostomy: man with a glass of iced water at a bright neighborhood diner, black SIIL ostomy belt at his waist — Grilled fish, mashed potatoes and cooked carrots: most menus have an easy option.

Easy orders: grilled fish or chicken, mashed or baked potato without skin, white rice, pasta with a mild sauce, soup.
Ask for: sauce on the side, vegetables cooked soft, no seeds or nuts on top.
Bring: a spare pouch and wipes, so the meal is about the company.

Choose clothing that leaves room for the pouch to function and lets you reach it easily. An ostomy belt or wrap with a pouch pocket is an optional clothing choice. It does not change digestion, treat high output or prevent a food blockage.

Specific food questions

When can I eat after new stoma surgery, and is a soft diet the same as low fiber?

Your surgical team decides when you can start and advance food. Early options may include white rice, pasta, eggs and tender fish, according to your plan. Low fiber describes fiber content; a soft diet describes texture. Ask which you need, particularly if swallowing is difficult. Reintroduce foods gradually when your team advises. Sources: NHS; CUH NHS

Can I eat wholemeal bread, corn or black-eyed peas?

Whole-wheat (wholemeal) bread contains more fiber; corn kernels and black-eyed peas also need consideration, particularly with a new ileostomy or a prescribed low-fiber diet. They are not permanently forbidden for every person. Follow your current restrictions, then try small amounts separately and chew thoroughly. Peas and other pulses may also increase gas. Sources: NHS; CUH NHS

What about lettuce and raspberries with an ileostomy?

Raw lettuce and raspberry seeds can be harder to manage during a low-fiber recovery phase. A food being soft does not remove its seeds or fiber. Ask when these foods fit your plan; when reintroducing them, test one at a time and observe your output rather than assuming they are safe for everyone. Source: CUH NHS

Can I have cooked eggplant, sweet potato, broccoli or other vegetables?

Preparation matters: peeled, well-cooked eggplant or sweet potato can be easier to fit into some lower-fiber plans than tough skins or raw vegetables. Check your own food list, especially with high output. Broccoli and other cruciferous vegetables may cause gas; they are not automatically banned. Introduce portions gradually and chew well. Source: CUH NHS

Are American cheese and lunch meat suitable for a new ileostomy?

Cheese and tender meat can provide protein, but this is not approval of every processed product. For American cheese or lunch meat, check added seeds, tough casings, spicy ingredients and your discharge advice. Choose a texture you can chew well, and discuss foods that repeatedly increase symptoms rather than removing whole food groups. Source: CUH NHS

Can chimichurri or wasabi make my pouch leak?

There is no blanket yes-or-no rule for these sauces. Chimichurri recipes vary in herbs, garlic, oil and chili; wasabi is pungent. Spicy or fatty foods can loosen output in some people. A leak also needs a pouch-fit check: do not assume a sauce is the only cause or rely on changing food to fix a leaking seal. Source: CUH NHS

Should I thicken output or change foods to prevent pancaking?

Rice, pasta or ripe banana may help thicken loose output, but do not aim for hard stool. Pancaking can involve thick, sticky output and a vacuum inside the pouch. Review your usual foods, fluid plan and pouch with your stoma nurse; adding large amounts of fiber or water is not a universal remedy. See our pancaking guide.

What changes if I also have Parkinson's disease?

Ask your stoma team and Parkinson's team or dietitian to agree one plan. Swallowing difficulties, weight changes, constipation, medicines and the type of stoma can change what is appropriate. Do not increase fiber or change food texture from a generic ostomy list; swallowing problems may need specialist assessment. Source: NHS

What should I eat after a stoma reversal?

Follow the plan for your operation: the remaining bowel and its recovery affect tolerance. Small, regular meals and a temporary lower-fiber diet may be advised before gradual reintroduction. A diet written for someone still using a pouch is not a complete reversal plan. Ask your surgical team about persistent symptoms or difficulty eating. Source: RUH NHS

Can you eat pizza with a stoma?

Usually yes, once you are back on a normal diet. A plain cheese slice on a thin crust is an easy first test. The toppings decide it: mushrooms, corn, olives and peppers are the ones to chew well, especially with an ileostomy. Very greasy or spicy pizza can loosen output for some people.

Can you eat curry or spicy food with a stoma?

Many people do. Start mild and in a small portion, because spice can loosen output or cause a burning feeling around the stoma for some people. Plain rice and yogurt on the side make it easier. Build up the heat gradually and note how you respond.

Can you eat chocolate with a stoma?

A small piece is fine for most people. Larger amounts, and rich chocolate desserts, can loosen output in some people, and chocolate with nuts or coconut needs extra chewing with an ileostomy.

Can I drink coffee and alcohol with an ostomy?

Most people can, in moderation, once their team agrees. Caffeine can speed up output, alcohol dehydrates and beer adds gas. With an ileostomy, drink water alongside and count only part of your coffee toward your fluids.
