Is Tim Hortons Sour Cream Glazed High in Histamine?

Tim Hortons Sour Cream Glazed

High histamine

This glazed doughnut runs high, mostly because of the sour cream and defatted soy flour in the batter.

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 Gluten Histamine Liberator

A sour cream glazed is a fried enriched-flour doughnut with sour cream, soy flour, and a sugar glaze.

Sour cream leads it — cultured dairy like sour cream is fermented, which pushes it high, and the defatted soy flour is high as well.
The rest is milder but stacks up — the enriched flour, soybean oil, and wheat starch each land moderate, so the base is not neutral even before the glaze.

A plainer yeast-raised option from the same case tends to be lower.
