Is Starbucks Blueberry Streusel Muffin High in Histamine?

Starbucks Blueberry Streusel Muffin

High histamine

This muffin is high in histamine, mainly from the buttermilk 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

It is a sweet muffin of wheat flour, sugar, blueberries, eggs, and buttermilk with a cinnamon streusel top.

Buttermilk — this is the main driver and runs high because it is cultured, which lets histamine accumulate in the dairy.
Wheat flour, soybean oil, and cinnamon — these each sit at moderate, and blueberries are a liberator food, so several parts of the muffin are working against you.

The cultured buttermilk is baked in, so this one cannot really be adjusted at the counter.
