Serving size, prep, and portion notes for soy sauce
Most people are surprised that standard soy sauce is brewed with wheat, so it grades as containing gluten and is not safe for celiac disease. On top of that it is fermented, which makes it very high in histamine and high in tyramine, the trigger that matters if you take an MAOI medication or get migraines from aged and fermented foods.
Watch for
Brewed with wheat, so ordinary soy sauce contains gluten and is not celiac-safe (look for a certified gluten-free tamari instead) / Very high in histamine from fermentation, a frequent flushing and headache trigger / High in tyramine, relevant on MAOI medications and for tyramine-driven migraines / A processed condiment that grades high in nitrites and pro-inflammatory
