Are Subway Pickles High in Histamine?

Subway Pickles

High histamine

Subway's pickles are cucumbers in vinegar brine, and pickling pushes them high in histamine.

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.

This topping is cucumber slices held in a mix of water, distilled vinegar, salt, alum, and turmeric.

Pickles — the pickling and brining process is what makes these high, since preserved cucumbers accumulate histamine in a way a fresh cucumber would not.
A fresh cucumber is different — the issue is the pickling, so an unpickled vegetable would be a much gentler choice.

Leaving the pickles off is the easy way to keep your sandwich lower.
