Sensitivity notes
Why gos food checker matters
Galacto-oligosaccharides (GOS) are carbohydrates found mainly in legumes and some vegetables. They're a FODMAP that can ferment in the gut, causing bloating and discomfort in sensitive people.
- Canned and rinsed legumes are lower in GOS than dried
- Start with smaller portions and build up tolerance
- Some people find beano-type enzymes helpful

Serving size, prep, and portion notes for portobello mushroom
Portobellos are just cremini mushrooms grown large and mature, and that big meaty cap is exactly why people reach for them on the grill. It is also why they are high FODMAP: they are loaded with mannitol, a sugar alcohol (polyol) that ferments in the gut. On top of that they are rich in free glutamate, the compound behind their savory, umami-heavy flavor, which can bother people sensitive to MSG-like foods.
Watch for
High in mannitol, a polyol FODMAP, so a grilled cap or two can trigger bloating, cramping and diarrhea in a sensitive gut / Naturally high in free glutamate, which gives the meaty umami taste but can be a trigger if you react to MSG or glutamate-rich foods / Poor choice during a SIBO-focused elimination because the fermentable polyols feed bacterial overgrowth
