Portobello mushroom

High FODMAP (Avoid)High in mannitol

Is portobello mushroom low FODMAP?

Portobello mushroom is high FODMAP and best avoided during the elimination phase.

Portobello is mannitol-heavy, high even at small servings, and cooking does not lower it. For that meaty bite, grilled oyster mushrooms or canned champignons are the gentle swaps.

FODMAP subgroups to watch

Portobello mushroom contains mannitol that can drive SIBO symptoms.

SIBO note

Watch this one for IMO (formerly methane SIBO). The fermentation pattern of portobello mushroom tends to feed this specific bacterial pattern more than other SIBO types.
