Is Tim Hortons Ham & Swiss Sandwich High in Histamine?

Tim Hortons Ham & Swiss Sandwich

High histamine

The Ham & Swiss is high, driven by the cured ham, tomato, and lemon juice concentrate.

Fast food is cooked in batches and held warm rather than made when you order it, so it is rarely as fresh as something cooked at home. That matters here because histamine builds up as protein foods sit, which means the same item can affect you differently depending on how long it waited.

Gluten Dairy Histamine Liberator

This sandwich layers cured pork, Swiss cheese, iceberg lettuce, sliced tomato, and a lemony spread on a cultured, malted bread.

Cured ham — the ham and swiss filling is high, since cured and smoked pork builds histamine as it is processed and held.
Tomato, lemon, and celery extract — the sliced tomato and lemon juice concentrate are classic liberators, the cultured celery extract is high, and the cultured rye and malted barley bread add moderate weight.

A warm, simpler item without cured meat, tomato, and the lemony spread would land much lower.
