Histamine Tracker
Sushi (vegetarian)
Rice vinegar and soy sauce are the main histamine contributors here — the vegetables themselves are generally low-risk.
Vegetarian sushi removes the high-risk fish factor, but a couple of key ingredients still carry histamine.
-
Rice vinegar — sushi rice is seasoned with vinegar, which is fermented and commonly reported as a trigger by people with histamine sensitivity
-
Soy sauce — the standard dipping sauce is fermented soy, which tends to be high in histamine; tamari is also fermented, though some people find pickled ginger adds to the load too
Asking for plain steamed rice instead of seasoned sushi rice, and skipping the soy dip, may make vegetarian rolls easier to tolerate.
