Can I eat orange juice with ulcerative colitis?
During a flare: CautionIn remission: Usually OK
Orange juice's natural acidity can add to stomach discomfort for some people, and like other juices it concentrates the sugar of the fruit without the fiber. Juice made from suitable fruits such as orange is generally considered low-FODMAP-friendly in small amounts, which sets it apart from higher-FODMAP juices like apple.
During a flare
The acidity and concentrated sugar can be a commonly reported irritant during a flare, so smaller diluted amounts tend to be better tolerated than a full glass.
In remission
Most people in remission tolerate orange juice reasonably well in modest amounts (roughly half a cup at a time), though individual acid sensitivity varies.
Ways to make it gentler
- Dilute with water
- Drink with food rather than on an empty stomach
Safer swaps
diluted orange juice · whole orange segments · water
