Culver's Really Reese's Flavor of the Day

High histamine

This peanut-and-chocolate custard is high, driven by cocoa, peanuts, and soy.

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 Histamine Liberator

It is a vanilla frozen custard loaded with milk chocolate, peanut butter cup pieces, and cocoa.

  • Cocoa and peanuts — cocoa processed with alkali and peanuts both run high, and they are the core of this flavor, so they set the level.

  • The soy — the soy in the mix is also high, so between the cocoa, peanuts, and soy there is no way to keep this one down.

The plain custard base is a much lower-histamine way to enjoy the same creamy treat.
