Is Subway Steak (Shaved) High in Histamine?

Subway Steak (Shaved)

High histamine

This shaved steak is high in histamine from the autolyzed yeast and dried tomato in the seasoning.

Food here is usually assembled to order from components that were prepped earlier in the day, so it tends to be fresher than a drive-through and less fresh than cooking at home. Histamine builds up as protein foods sit, so how long the chicken or beef has been in the warmer matters as much as what is in the bowl. Treat the rating above as a starting point.

Histamine Liberator

This is thin sliced beef mixed with savory seasonings, and a couple of those seasonings run high.

Autolyzed yeast — this is high in histamine and is a big part of why the steak lands where it does.
Dried tomato — tomato is a classic histamine liberator, and in dried form it is high, adding to the level; soybean oil sits moderate alongside.

A plainer protein like the rotisserie-style chicken is a lower-histamine choice here.
