Is Culver's Brownie Thunder Flavor Of The Day High in Histamine?

Culver's Brownie Thunder Flavor of the Day

High histamine

This sundae is high, driven by the cocoa brownie folded into the frozen custard.

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.

Brownie Thunder layers vanilla frozen custard (milk, cream, sugar, egg yolk) with chunks of chocolate brownie made from wheat flour, cocoa, and soybean oil.

Cocoa brownie — cocoa is a classic histamine liberator, and it is the main thing pushing this dessert high.
Enriched wheat flour and soybean oil — the brownie base also brings moderate flour and oil, adding to the cocoa on top.

The custard on its own is the mild part, so a plain scoop without the brownie is the smarter route.
