What to know about gluten-free soy sauce
Gluten-free soy sauce, usually tamari, solves one problem and leaves another. It swaps out the wheat of regular soy sauce, so it is genuinely gluten-free and low-FODMAP. But it is still a long-fermented soy product, which makes it very high in histamine, high in tyramine and very high in free glutamate. So it is a good pick for gluten or FODMAP concerns and a poor one if your trigger is histamine, tyramine or umami/MSG-type reactions.
Watch for
- Very high in histamine, because the long fermentation that makes soy sauce also builds histamine, a common cause of flushing, headaches and congestion after Asian meals
- High in tyramine, which matters if you take an MAOI or get tyramine-triggered migraines
- Very high in free glutamate, the natural umami that acts like MSG for people who react to it
- The upside: unlike regular soy sauce, tamari is made without wheat, so it is gluten-free and low-FODMAP
