Is Firehouse Subs Seasoned Chicken Breast High in Histamine?

Firehouse Subs Seasoned Chicken Breast

Low histamine

This seasoned chicken breast is low in histamine, a fresh protein with simple seasoning.

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.

Just chicken breast with a light seasoning of glucose solids, rice starch, salt, and spices, and none of it flags high.

Fresh chicken breast — plain, uncured poultry is naturally low, unlike the cured and fermented meats on the menu.
Simple seasoning — the salt, starch, and spices are mild additions that keep the whole thing gentle.

This is one of the easier picks on the menu, so build your sub around it.
