Tim Hortons Iced Latte with Golden Cinnamon Cold Foam

High histamine

This iced latte is high, driven by the buttermilk in the golden cinnamon cold foam.

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.

Histamine Liberator Dairy

It is espresso with reduced fat milk over ice, finished with a sweet cinnamon-flavored foam.

Buttermilk in the foam — buttermilk is cultured, fermented dairy, and that fermentation is where the histamine comes from, which is what makes the whole drink high.
The cold foam blend overall — the flavored foam as made lands moderate beyond the buttermilk alone, so the topping is really the part carrying the weight here. The espresso and milk in the latte itself are much gentler.

Dropping the golden cinnamon cold foam leaves you with a far milder latte.
