Firehouse Subs Catering Salad Chopped Deluxe Turkey

High histamine

This turkey salad is high in histamine because of the tomatoes and provolone.

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 Dairy

It is lettuce, cucumber, red onion, and turkey with a few higher-histamine additions.

  • Tomatoes and provolone — tomato is a classic histamine liberator and aged provolone is high, so those two set the level.

  • Green peppers — these come in moderate, adding to the picture without leading it.

The turkey, lettuce, and cucumber are the calm parts, so leaning on those keeps things lower.
