Tim Hortons Iced Coffee with Golden Cinnamon Cold Foam

High histamine

This iced coffee runs high, mostly because the cold foam is built on buttermilk.

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.

Dairy Histamine Liberator

It is brewed arabica coffee with milk and cream, poured over ice and topped with a sweet golden cinnamon foam.

Buttermilk in the foam — buttermilk is a cultured, fermented dairy, and fermented dairy tends to carry a lot of histamine, which is what pushes this drink into the high range.
Organic cinnamon — the cinnamon in the foam lands moderate on its own, so it adds to the picture even though the buttermilk is the bigger driver. The plain coffee, milk, and cream underneath are much milder.

Skipping the golden cinnamon cold foam gets you to a much friendlier drink.
