Subway Pepperjack Cheese

Moderate histamine

Subway's pepperjack is moderate, mostly from the jalapeno and red bell pepper folded into a fresh cheese.

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.

Dairy Histamine Liberator

This is a fresh, cultured cheese made from milk and cream with bits of pepper mixed in.

  • Jalapeno and red bell pepper — these two peppers are moderate histamine liberators, and they are what nudge this cheese up rather than the fresh dairy base itself.

  • The cheese base is milder — unlike an aged cheddar or parmesan, this is a young, cultured cheese, so the milk and cream do not carry the same load. The peppers set the tone here.

A plain fresh cheese without the peppers keeps things lower.
