Is Tim Hortons Frozen Lemonade High in Histamine?

Tim Hortons Frozen Lemonade

High histamine

This frozen lemonade is high in histamine because lemon is a histamine liberator.

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

This is a slushy lemonade made with sugar and lemon juice concentrate plus lemon flavor.

Lemon juice concentrate and lemon flavor — citrus is a classic histamine liberator, and the concentrated lemon here is exactly what pushes the drink high.
No easy fix — the lemon is the whole identity of the drink, so there is no way to keep it lemony and low at the same time.

Since the lemon is the driver, a non-citrus drink from the same menu is the smarter pick.
