Is Firehouse Subs Catering Sub Platter High in Histamine?

Firehouse Subs Catering Sub Platter

High histamine

This platter is high in histamine mainly from the ham, roast beef, provolone, and tomato.

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.

Gluten Dairy Histamine Liberator

This sub platter stacks turkey, ham, roast beef, provolone, tomato, onion, and lettuce on white rolls with balsamic dressing.

Cured and aged toppings — the ham and roast beef are cured deli meats and the provolone is an aged cheese, and all three run high, which sets the tone for the whole platter.
Tomato on top — tomato is a classic histamine liberator, so it adds to the load even beyond the meats and cheese, while the roll, lettuce, and onion are the milder parts.

A fresh turkey sub with lettuce and onion, no cured meats, cheese, or tomato, lands much lower.
