High FODMAP
Avoid during elimination. Save for a structured reintroduction challenge.
Safe serving
Common mushrooms: none. Oyster mushrooms: 75 g
FODMAP group responsible
- Mannitol — Polyols. Cauliflower, mushrooms, celery, sweet potato.
Why
Common button, portobello and field mushrooms are high in mannitol. Oyster mushrooms are the exception and are low FODMAP at 75 g, as are canned champignons that have been drained, since mannitol is water-soluble and leaches into the brine.
What to use instead
Oyster mushrooms
Low FODMAP at 75 g and the closest thing to a like-for-like swap.
