Is Firehouse Subs Gluten Free Ciabatta Roll High in Histamine?

Firehouse Subs Gluten Free Ciabatta Roll

Moderate histamine

This gluten-free roll is a rice and corn starch base raised with yeast, which lands it 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.

Gluten

A yeasted gluten-free bread built on corn and rice starches with psyllium for structure.

Added yeast — the yeast used to raise the roll is the moderate driver that sets its level, which is common for risen breads.
The starch base is mild — the corn starch, rice flour, and psyllium husk are gentle on their own, so it is the yeast doing most of the lifting here.

It is a solid gluten-free choice, just not the lowest-histamine option on the menu.
