Can I eat bell peppers with ulcerative colitis?
During a flare: CautionIn remission: Usually OK
Monash FODMAP testing shows green bell pepper is low FODMAP while red bell pepper is high FODMAP, so color matters for tolerance. Peppers also have a tough, shiny skin that adds insoluble fiber, and as a nightshade they contain small amounts of solanine, though Cedars-Sinai notes evidence that nightshades are harmful is weak.
During a flare
Peeled, deseeded, and well-cooked pepper (especially green) is generally easier than raw pepper with skin during a flare.
In remission
Raw peppers, including red and other colors, are usually fine to reintroduce as tolerated.
Ways to make it gentler
- peel or roast to loosen the skin
- remove seeds and pith
- start with green pepper if experimenting
Safer swaps
cooked zucchini
