High FODMAPLast reviewed October 24, 2026
Good to know
Most mushrooms are high in mannitol, a polyol, and also contain fructans, so they are usually limited during elimination. Common button, portobello and porcini mushrooms all fall into this group.
For a similar meaty texture, try eggplant. For depth of flavor in sauces and stews, a little miso or soy sauce works well. Mushrooms are a good test food for the mannitol group during reintroduction.
Mushrooms on a low FODMAP diet
- Leave mushrooms out during the elimination phase, which usually lasts two to six weeks.
- Use one of the lower-FODMAP swaps below instead.
- High FODMAP doesn't mean forever: during reintroduction, many people find they tolerate some high FODMAP foods in smaller amounts.
Which FODMAPs are in mushrooms
Mannitol: Mannitol is a polyol (sugar alcohol) found in some vegetables such as mushrooms and cauliflower. It is poorly absorbed and can draw water into the bowel. Read more about polyols and foods that cause bloating.
Fructan: Fructans are chains of fructose found in wheat, garlic, onion and some vegetables. People can't fully digest them, so they reach the large intestine, where gut bacteria ferment them. Read more about high FODMAP foods to avoid with IBS.
