What to know about miso paste
Miso paste is fermented soybean, and its deep savoury taste is a clue to its triggers. The long koji ferment builds free glutamate, which is the umami you taste and the reason miso reads like a natural MSG, and it also raises histamine and tyramine. On top of that the soybean base is high in GOS, a FODMAP, and many misos are cultured on barley so they are not reliably gluten-free. If a bowl of miso soup leaves you flushed, headachey or bloated, the fermentation and the soy are usually behind it.
Watch for
- High in free glutamate from fermentation, the umami hit that can read like MSG for people who are glutamate sensitive
- High in histamine and tyramine because it is aged for months, so it can drive flushing and headaches
- High in GOS from the soybean, a FODMAP that can cause gas and bloating
- Often made with barley koji, so it is not dependably gluten-free unless labelled
