Tim Hortons Peanut Butter Chocolate ICED CAPP® topped with Reese's

High histamine

This iced coffee drink is high, driven by cocoa, milk chocolate, and peanuts.

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 a blended coffee drink with milk, cream, and sugar, layered with cocoa, milk chocolate, and peanuts.

Cocoa and milk chocolate — both cocoa and chocolate read high, and together they are a big part of why this drink lands where it does.
Peanuts — the peanut topping and peanut flavor also run high, adding to the level alongside the chocolate.

A plain coffee with a splash of milk is a much lower-histamine choice on the same menu.
