Is Subway Monterey Cheddar Bread High in Histamine?

Subway Monterey Cheddar Bread

High histamine

This bread is high in histamine because of the aged cheddar baked into the top.

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 Gluten

This is a plain wheat loaf topped with a blend of cheeses, and the aged cheddar is what pushes it up.

Cheddar cheese — because it is aged, cheddar carries a lot of histamine, and here it is baked right into the crust so it cannot be picked off cleanly.
Monterey jack and the dough — the monterey jack cheese, plus the wheat flour and yeast in the bread, sit in the moderate range and add to the picture.

A plain, cheese-free bread is a much lower-histamine base to build a sandwich on.
