Subway Monterey Cheddar Blend

High histamine

Subway's Monterey cheddar blend is high in histamine because of the aged cheddar in the mix.

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

This shredded blend combines Monterey jack and cheddar with a couple of starches to keep it loose.

  • Cheddar leads — cheddar is an aged cheese, and aging is exactly what builds histamine, so it sets the level high on its own.

  • Monterey jack adds more — it sits at moderate, so even the milder half of the blend keeps this on the higher side.

A fresher cheese slice on the same menu is a much gentler pick.
