Is Subway Black Forest Ham High in Histamine?

Subway Black Forest Ham

High histamine

Subway's Black Forest ham 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.

This is a cured and smoked ham, which is what puts it high.

The ham leads — curing and smoking the pork builds up histamine, so the meat itself is the main driver.
Vinegar adds a little — the vinegar in the mix is moderate, so it nudges things but the cured ham is what sets the level.

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