Is Firehouse Subs Chili High in Histamine?

Firehouse Subs Chili

High histamine

This chili is high, driven mainly by the diced tomatoes and tomato sauce, with kidney beans and peppers adding to it.

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.

Histamine Liberator

A hearty bowl of beef, kidney beans, tomatoes, onions, and peppers seasoned with chili powder.

Tomatoes lead it — the diced tomatoes and tomato sauce are classic histamine liberators, and here they form the base of the whole dish.
Beans and peppers stack on — the cooked kidney beans, green bell peppers, chili, and chili powder are each moderate, so even setting the tomato aside the dish stays elevated.

Because the tomato base is core to what chili is, there's no simple tweak to bring it down here.
