Tim Hortons Double Stacked Sausage & Bacon Breakfast Sandwich

High histamine

This is high in histamine from the cured bacon, sausage, and added flavor ingredients.

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 stacks pork sausage and cured bacon with egg and cheese on an enriched-flour bun.

Cured pork and flavorings — the bacon is cured with sodium nitrite and smoke flavoring, and cured, smoked pork runs high, backed up by autolyzed yeast and lemon powder, a citrus liberator, in the seasoning.
The bun — the enriched flour and yeast in the bread sit at moderate, adding to the picture on top of the meats.

A simpler egg-based breakfast without cured pork would be much lower.
