IBS: what to eat and what to avoid
Irritable bowel syndrome (IBS) can improve a lot with changes in nutrition. The key isn't to ban foods, but to identify what sits well with you and what triggers symptoms, which is very individual.
What is IBS?
IBS is a common digestive disorder with abdominal pain or discomfort, gas, bloating and changes in bowel habits (diarrhea, constipation or both). It doesn't damage the gut, but it greatly affects quality of life. Food, stress and sleep all play a major role.
Foods that usually help
- Soluble fiber (oats, ripe banana, cooked carrot) is usually well tolerated.
- Regular meals in moderate portions, without skipping.
- Good hydration and gentle cooking methods.
- Chewing slowly and eating calmly.
Foods that often worsen symptoms
- Ultra-processed foods, fried foods and excess fat.
- Alcohol, lots of caffeine and carbonated drinks.
- Polyol sweeteners (sorbitol, mannitol) and excess of some fermentable sugars.
The low-FODMAP diet (with support)
FODMAPs are certain carbohydrates that ferment in the gut and can trigger symptoms. The low-FODMAP diet has good evidence, but it's a phased tool (elimination, reintroduction and personalization) that shouldn't be done forever or without guidance: done poorly, it impoverishes your diet and microbiota. That's why it's best done with support.
Beyond food
The gut and brain are closely connected. Stress and poor sleep worsen IBS, so an integral approach (nutrition, habits and stress management) works better than focusing on diet alone.

Is the low-FODMAP diet forever?
No. It's a phased tool: you reduce FODMAPs for a while, then reintroduce them to identify your triggers and personalize. Staying on it permanently isn't recommended.
Should I cut out gluten or lactose?
Not necessarily. Some people with IBS tolerate lactose or certain foods poorly, but it's individual; it's best to check with support rather than cutting by default.
Does stress affect IBS?
Yes. The gut-brain axis means stress and poor sleep worsen symptoms. That's why an integral approach works better.
