Can I eat butter with ulcerative colitis?
During a flare: CautionIn remission: Usually OK

Butter is naturally low in lactose since it's mostly milk fat with only trace amounts of milk solids, so lactose intolerance is rarely the issue with butter specifically. The concern during active ulcerative colitis is more about fat load in general: large amounts of any concentrated fat can be harder to digest and may worsen diarrhea during a flare.
During a flare
Small amounts used in cooking are usually fine even during a flare since lactose content is minimal; the main caution is not overdoing total fat intake.
In remission
Typically well tolerated in remission in normal cooking amounts.
Ways to make it gentler
- Use in moderation rather than large amounts
- Ghee (clarified butter) removes remaining milk solids if sensitivity persists
Safer swaps
ghee · plant-based oils
