How we classify Subway restaurant risk
IsItFODMAP does not certify restaurant meals. We classify restaurant risk by breaking the order into ingredients, checking known FODMAP trigger groups, considering portion size, and using conservative wording when menus or preparation can change.
For strict elimination, treat this page as a question list: what is in the bread, sauce, seasoning, dairy, sweetener, beans, fruit, and large mixed portions?
Classification signals
- Garlic, onion, wheat, lactose, beans, polyols, honey, and high-FODMAP fruits.
- Current restaurant ingredient labels when available.
- Serving-size caution and individual tolerance.
- Clear disclaimers instead of medical guarantees.
