Tim Hortons Iced Matcha with Golden Cinnamon Cold Foam

High histamine

This iced matcha is high in histamine because the buttermilk in the cold foam is high.

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

This is an iced matcha milk drink topped with a sweetened golden cinnamon cold foam.

Buttermilk in the cold foam — buttermilk is a cultured dairy, and cultured dairy runs high, which is what lifts the whole drink up.
The cold foam itself — the golden cinnamon cold foam adds a moderate layer, while the matcha and fresh milk underneath are milder.

The matcha and milk base is fine on its own; the cold foam is what carries the level here.
