Are Subway Green Peppers High in Histamine?

Subway Green Peppers

Moderate histamine

Subway's green peppers are just fresh green bell pepper, and they land moderate.

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 topping is simply sliced green bell pepper, nothing else added.

Green bell pepper — bell peppers sit at a moderate level, so as a topping they nudge a sandwich up a little on their own.
Nothing else in play — there is no sauce, cure, or aging here, so the pepper is the only thing setting the level.

If you want a lower-histamine crunch, swap the green peppers for cucumber or red onion.
