Is Firehouse Subs Salami High in Histamine?

Firehouse Subs Salami

High histamine

Salami is high in histamine because it is a cured, fermented meat made with red wine.

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.

DAO Blocker

This is a classic cured salami of pork and beef with salt, spices, red wine, and nitrate curing salts.

Cured, fermented salami — the meat is fermented and cured with a lactic acid starter and sodium nitrate, which builds histamine as it ages.
Red wine — the wine folded into the mix is high and also acts as a DAO blocker, which can make the effect more noticeable.

A fresh, uncured protein on the same menu is a far gentler choice.
