Can I eat mushrooms with ulcerative colitis?
During a flare: CautionIn remission: Caution

Mushrooms are particularly rich in mannitol, a sugar-alcohol FODMAP that Monash FODMAP research identifies as a common driver of bloating and loose stools when it ferments in the gut. Cooked, small portions are generally easier to manage than large or raw amounts.
During a flare
Best limited or avoided during a flare, especially raw; small, well-cooked portions may be better tolerated if you choose to try them.
In remission
Tolerance is dose-dependent and individual; keep portions modest and watch for bloating.
Ways to make it gentler
- cook thoroughly
- keep portions small
Safer swaps
cooked zucchini · cooked carrots
