Can I eat yogurt with ulcerative colitis?
Yogurt's live bacterial cultures partially digest lactose during fermentation, so it's often better tolerated than milk even by people with lactose intolerance. A systematic review of dairy in IBD found yogurt was consistently reported as beneficial across studies, unlike dairy overall, and animal and lab research suggests some yogurt cultures have anti-inflammatory, gut-barrier-supporting effects, though human trial evidence specific to ulcerative colitis is still limited.
During a flare
Plain yogurt with live active cultures is one of the more commonly tolerated dairy foods during a flare, but stop if it triggers symptoms and watch added sugar in flavored versions.
In remission
A reasonable food to reintroduce in remission; choosing options labeled 'live and active cultures' may help with tolerance and gut support.
Ways to make it gentler
- Pick plain, unsweetened yogurt with live active cultures
- Try lactose-free or Greek yogurt if regular yogurt still causes symptoms
Safer swaps
Greek yogurt · kefir · lactose-free yogurt
