Is Subway Bacon High in Histamine?

Subway Bacon

High histamine

Subway's bacon is high in histamine because it is a cured, smoked pork product.

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.

Bacon is cured and smoked pork, and that is what drives its level.

The bacon is high — curing and smoking the pork builds up histamine, so the meat itself carries the rating.
The rest is just seasoning — the salt, sugar, and cure agents are supporting ingredients, so the cured pork sets the level on its own.

For a lower-histamine pick from the same menu, a freshly cooked chicken or turkey option tends to be gentler.
