Why glutamates food checker matters

Glutamates, including MSG, are flavor enhancers found naturally in many foods and added to others. Some people report sensitivity causing headaches, flushing, or other symptoms, though research on 'MSG syndrome' is mixed.

  • MSG goes by many names - look for 'glutamate' on labels
  • Naturally high in soy sauce, fish sauce, and aged cheeses
  • Tomatoes and mushrooms are naturally high in glutamates
  • Yeast extract and hydrolyzed proteins contain glutamates
  • Fresh, unprocessed foods are generally lower

What to know about 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
