Tim Hortons Iced Matcha Latte with Strawberry Cold Foam

High histamine

This iced matcha is high because the strawberry cold foam contains 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

This is matcha green tea with reduced fat milk over ice, topped with a sweet strawberry cold foam.

Buttermilk in the cold foam — buttermilk is cultured, so it runs high, and that is what sets this drink high.
The matcha base — the matcha, fresh milk, and sugar underneath are milder, so the cold foam is really the deciding piece.

Without the strawberry cold foam, the matcha and fresh milk base lands lower.
