What to eat with IBS (irritable bowel syndrome)
In short: with irritable bowel syndrome (IBS) there is no single "right" menu that works for everyone. Still, most people notice that simple, warm, not-too-greasy home meals are easier to handle than a big plate of fried, spicy or fizzy food. A smaller portion, a calm eating pace and some attention to your own reactions often help, too. Below are the usual starting points and why, in the end, you'll build your own list.
This is general information, not personal advice. IBS comes in different forms, and what suits one person may not suit another. So the main tool here is paying attention to yourself, not copying someone else's "perfect" diet.
Why foods affect people differently
With IBS the gut can be more sensitive to stretching and to certain substances in food. One common reference point, usually discussed together with a doctor or dietitian, is the low-FODMAP approach. Put simply: FODMAPs are a group of short-chain carbohydrates that are poorly absorbed and ferment actively in the gut. In some people, these are linked to bloating, rumbling and discomfort.
It's worth keeping in mind: FODMAPs are not "bad" foods. They're simply substances a sensitive gut may react to more strongly. Many of these foods are calmly brought back into the diet after a period of observation, sometimes in smaller amounts.
What more often irritates and what's usually easier to tolerate
The table below shows general tendencies, not rules. Your personal picture may differ, so treat it as a starting point for your own observations.
| Category | Often easier to tolerate | More often a trigger |
|---|---|---|
| Vegetables | Carrot, zucchini, potato, spinach, cucumber | Onion, garlic, cabbage, legumes |
| Fruit | Banana (moderately ripe), orange, blueberries | Apple, pear, watermelon, dried fruit |
| Grains | Rice, oats, buckwheat, quinoa | Large portions of wheat and rye |
| Protein | Chicken, fish, eggs, tofu | Very fatty or fried dishes |
| Dairy | Hard cheeses, lactose-free options | Large portions of milk, soft cheeses |
Alongside the foods themselves, the cooking method and portion size often matter. The same dish, stewed and in a small amount, can feel quite different from one that's fried and heaped high.
Simple, "calm" home meals
When you want something predictable, people often come back to a few basic dishes. They're light, made from a short list of ingredients, and easy to adjust to suit you:
- Rice with chicken and carrot — boiled or baked chicken, rice and a little carrot. A neutral base that's easy to build on.
- Oatmeal with water or lactose-free milk — with banana or a handful of blueberries instead of apple.
- Baked fish with potato — white fish, potato, a little oil and some fresh herbs. No heavy crust.
- Buckwheat with stewed zucchini — a gentle side that's easy to round out with an egg or a piece of chicken.
- Herb omelet — a quick option for when you don't have the energy to cook anything complicated.
Instead of onion and garlic for flavour, people often use the green part of leek, fresh herbs, or a little garlic-infused oil — this gives aroma without the "heavier" parts themselves.

Find a dish →Why everyone's triggers are different
IBS is a very individual condition. For some, discomfort is linked to legumes; for others, to coffee or a big serving of raw vegetables; and some people eat almost anything calmly but react to rushing and stress while they eat. That's why copying someone else's list of "allowed" foods rarely works.
The most reliable way to figure it out is to keep simple notes. For a few weeks, jot down what you ate, in what amount, and how you felt afterwards. Over time, patterns emerge and you see your own personal triggers rather than general ones. Such a diary is also very useful at an appointment with a doctor or dietitian.
If you want to try the low-FODMAP approach seriously, it's usually done with a dietitian's guidance: first some foods are temporarily removed, then gradually reintroduced one by one to see the reaction. Doing this blindly and for a long time isn't a good idea — your diet should stay varied.
A few small things that often help
- Eat in smaller portions, but regularly, without long gaps.
- Don't rush, chew well, and eat in a calm setting when you can.
- Drink enough water through the day.
- Think ahead about a few "safe" dishes for yourself, so you're not deciding everything on an empty stomach.
And when you're tired of wondering "what should I cook today", this routine gets simpler: enter the foods you usually tolerate well into abc-eat, and the service will suggest what to put together from them.
When to see a doctor
Food is only part of the story, and it doesn't replace a medical consultation. Be sure to see a doctor if you notice:
- blood in your stool or black stools;
- noticeable weight loss with no clear reason;
- severe or constant pain, especially at night;
- a fever that keeps coming back or won't go away;
- symptoms that first appeared after age 50;
- discomfort that gets in the way of daily life despite changes in your food.
Only a doctor can give an accurate diagnosis and plan. If you suspect IBS or already have a diagnosis, it's worth discussing your diet specifically with a doctor or dietitian — and keeping track of your own reactions will make that conversation far more concrete.
