Italian Sub Sandwich

High histamine

An Italian sub is high because the salami, ham, pepperoni, provolone, and tomato are all high.

Dairy Histamine Liberator Gluten

An Italian sub piles salami, ham, pepperoni, provolone, lettuce, tomato, onion, and Italian dressing onto white bread.

  • Cured meats and aged cheese lead — salami, ham, and pepperoni are cured, and provolone is aged, so each one runs high on its own and defines the sandwich.

  • Tomato and dressing add more — tomato is a classic histamine liberator, the Italian dressing is moderate, and together they keep the level up even before the meats.

The bread, lettuce, and onion are the mild parts, but the fillings are what make this one high.
