Can I eat cucumbers with ulcerative colitis?
During a flare: CautionIn remission: Usually OK
Cucumber is low FODMAP per Monash FODMAP testing, but its skin and seeds are still raw, insoluble-fiber-containing textures that low-fiber diet guidance suggests avoiding during active symptoms in favor of peeled, seeded, or cooked vegetables.
During a flare
Peel and deseed cucumber, or skip it, during a flare.
In remission
Usually fine with skin and seeds once symptoms are stable.
Ways to make it gentler
- peel and deseed if sensitive
