Is Tim Hortons Iced Matcha Protein Latte High in Histamine?

Tim Hortons Iced Matcha Protein Latte

Low histamine

This iced matcha is low in histamine, made from fresh milk, whey protein, matcha, and a little cane sugar.

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 a cold milk and matcha drink with added whey protein and a light sweetener.

Fresh milk and whey base — reduced fat milk and whey protein isolate are fresh, unfermented dairy that stay low, and matcha green tea was not flagged as a driver.
Sweeteners and stabilizers — cane sugar, dextrose, soy lecithin, xanthan gum, and pectin are for sweetness and texture and do not raise the level.

This is an easy low-histamine option if you want something cold and green.
