Is Subway Pepperoni High in Histamine?

Subway Pepperoni

High histamine

Subway's pepperoni is high in histamine because it is a cured, fermented pork and beef sausage.

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.

Pepperoni is a cured and fermented meat, which is what drives its histamine level.

The pepperoni is high — curing the pork and beef with a lactic starter culture and letting it ferment builds up histamine.
Nothing here brings it back down — the salt, spices, and dextrose are just seasonings, so the cured meat sets the level on its own.

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