Soy Sauce & histamine FAQ
Is Soy Sauce high in histamine?
High in histamine — a fermented condiment to limit. Soy sauce is brewed by fermenting soybeans and wheat for months, which makes it high in histamine despite being used in small amounts. Because a little goes onto so many dishes, it is an easy hidden trigger. For salty, savoury seasoning, fresh sea salt or a splash of homemade broth avoids the fermented load.
Can I eat Soy Sauce on a low-histamine diet?
Soy Sauce is generally best avoided on a strict low-histamine diet because it can be high in histamine. Tolerance is individual, so track your own response before reintroducing it.
