Is Tim Hortons Grilled Cheese Panini High in Histamine?

Tim Hortons Grilled Cheese Panini

Moderate histamine

The Grilled Cheese Panini is moderate, mostly from the enriched wheat flour and yeast in the bread.

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

This panini is pressed bread made from enriched wheat flour and yeast with a fresh dairy cheese filling of milk, cream, and milk fat.

The bread base — the enriched wheat flour and yeast each sit at moderate, and together they set the overall level here.
Fresh cheese — the milk, cream, and milk fat are fresh, unfermented dairy, so they stay mild and are not what drives the rating.

This is one of the more moderate hot items, and there is no cured meat or tomato to push it higher.
