Can I eat oranges with ulcerative colitis?
During a flare: Usually avoidIn remission: Caution
The fibrous membranes separating orange segments are insoluble fiber that can be hard to break down during active inflammation, and citrus acidity is a commonly reported irritant for some people even though the fruit itself is low-FODMAP.
During a flare
Whole oranges (and grapefruit) are commonly grouped with fruits to limit during a flare because of their fibrous segments.
In remission
Orange juice without pulp, or a small amount of segmented flesh, is often better tolerated than eating the whole fruit; helps with iron absorption when paired with iron-rich meals.
Ways to make it gentler
- Strain juice to remove pulp
- Remove membranes if eating segments
Safer swaps
