Is Subway Meatballs & Marinara High in Histamine?

Subway Meatballs & Marinara

High histamine

Meatballs & marinara are high in histamine because the tomato sauce, romano, and soy protein are all high.

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 is beef-and-pork meatballs with breadcrumbs and cheese in a tomato-based marinara, and several parts run high.

Tomato puree and canned tomatoes — tomato is a classic histamine liberator, and the puree and canned tomato in the marinara are both high, setting the tone.
Romano cheese and soy protein — the aged romano is high, and the textured soy protein concentrate is high too; the breadcrumbs and wheat flour add moderate notes.

A plain, non-tomato protein is a much lower-histamine choice on this menu.
