Can I eat lettuce with ulcerative colitis?
During a flare: CautionIn remission: Usually OK
Lettuce is low FODMAP per Monash FODMAP testing and is mostly water, but as a raw, high-volume salad vegetable it's still commonly grouped with other raw produce that low-fiber diet guidance suggests limiting until active symptoms settle.
During a flare
Large raw salads are often harder to manage during a flare; smaller portions of shredded or finely chopped lettuce may be easier.
In remission
Usually well tolerated in typical salad portions once symptoms are stable.
Ways to make it gentler
- chop or shred finely
- start with smaller portions during a flare
