Tim Hortons Boston Cream
This doughnut is high, mainly because of the cocoa in its chocolate topping.
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.
This is a yeast doughnut with a cream filling and a chocolate glaze on top.
-
The cocoa leads it — cocoa is a known histamine liberator, and the chocolate topping is what pushes this doughnut into high territory.
-
The dough adds to it — the enriched flour, yeast, soybean oil, and wheat starch each sit at moderate, so the base is already on the middling side before the topping.
A plain glazed or non-chocolate doughnut on the menu tends to be the gentler pick.
