TLDRLast updated 3 September 2026
Yes. Cucumber is low FODMAP at the tested serve of ½ cup sliced (75 g), which contains only traces: 0.02 g of fructans and 0.02 g of sorbitol, with the other four FODMAP groups at zero. Mostly water and crunch, cucumber is one of the easiest salad vegetables to keep on an IBS plate.

Is cucumber low FODMAP?
Cucumber barely registers on the FODMAP scale. At the tested 75 g serve the data shows 0.02 g of fructans and 0.02 g of sorbitol, and nothing at all from fructose, lactose, GOS or mannitol. For context, fructans only become moderate above 0.1 g and sorbitol above 0.2 g, so cucumber sits at a fraction of the levels that start to matter. That is what you would expect from a vegetable that is overwhelmingly water, and it is why cucumber earns a comfortable green rating.
Cucumber and IBS: what to know
Cucumber is one of the gentler raw vegetables, useful if salads normally feel risky, since it is low in the fermentable fibre that makes some raw veg hard work. A few people find the skin or seeds sit heavily; peeling or scooping the seeds changes the texture without changing the green rating. If a cucumber dish does cause symptoms, look at the dressing first, because creamy or garlicky dressings are far more likely culprits than the cucumber underneath.
Gut-friendly ways to eat cucumber
Cucumber is a natural base for gut-friendly salads with tomato, carrot and leaves like romaine, dressed with olive oil and lemon. For a low FODMAP take on tzatziki, grate it into lactose-free yoghurt with mint and garlic-infused oil. It also works as a crunchy dipper in place of crackers, and a few slices lift a sandwich without adding anything your gut has to think about.

Frequently asked questions
Can I eat cucumber with IBS?
Yes. The tested ½ cup sliced (75 g) rates green, and cucumber is one of the few salad vegetables you can pile on without watching the portion. It works as a snack, a sandwich filler and a salad base. If a cucumber-based dish has ever bothered you, the dressing or the onion in the salad is the more likely cause.
Should I peel cucumber for IBS?
Not for FODMAP reasons: the green rating applies to cucumber as it comes, and the skin is not a FODMAP source. Some people simply find the skin and seeds sit better removed, which is about fibre texture rather than fermentable carbohydrates. Try it both ways and keep whichever your gut prefers.
Are pickles low FODMAP?
The cucumber going into them is: 75 g rates green with only trace FODMAPs. Commercial pickles are a label-reading exercise, though, because some brines include garlic, onion or high FODMAP sweeteners. A simple vinegar, salt and dill pickle keeps the closest to plain cucumber’s clean profile.
Is cucumber OK during the FODMAP elimination phase?
Yes, and it earns its place: the elimination phase is when raw, crunchy food gets scarce, and cucumber delivers that texture at a green rating. Pair it with other green-rated salad staples like carrot and romaine for a bowl you can eat without measuring.
