Is Subway Veggie Patty High in Histamine?

Subway Veggie Patty

High histamine

Subway's Veggie Patty is high in histamine, mainly from the soybeans and spinach blended into 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

This patty packs together carrot, onion, green beans, zucchini, broccoli, corn, and more, but a couple of ingredients set the level.

Soybeans and spinach lead — the patty is bound with soybeans and soy flour, and soy runs high, while spinach is a classic histamine liberator, so together they push the whole patty up.
Oat bran and red bell pepper add to it — both sit at moderate, so even setting the soy and spinach aside, this stays a higher-histamine choice.

Since the patty itself is the problem, a different protein on the same menu is the cleaner route.
