What to know about mushroom
Mushrooms are a rare food that lands high on several unrelated trigger scales at once. They are one of the richest natural sources of free glutamates, the umami compound linked to MSG-type reactions, and they are high in salicylates. They are also high in polyols (mannitol), a FODMAP that ferments in the gut, and moderate in histamine. That stack is why mushrooms can bring on headaches, bloating or flushing even though they look like a plain, healthy vegetable.
Watch for
- One of the highest natural sources of free glutamates, so they can trigger MSG-style headaches or flushing
- High in salicylates, a common trigger for people sensitive to aspirin or salicylate-rich foods
- High in polyols (mannitol), a FODMAP that causes bloating and gas in a sensitive gut
- Moderate in histamine, which can add to symptoms if you have histamine intolerance
