Is Sonic Banana Puree High in Histamine?

Sonic Banana Puree

Moderate histamine

Banana puree is a sweetened fruit blend that lands moderate because banana is a histamine liberator.

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.

Histamine Liberator

This is a corn syrup and banana blend used to flavor drinks and desserts, and the banana is the reason it is moderate.

Banana puree — banana is a classic histamine liberator, and that holds true whether it is fresh or pureed, which sets the level here.
The rest is milder — the corn syrup, sugar, ascorbic acid, and citric acid are there for sweetness and preservation and are not the drivers.

Choosing a non-banana flavor add-in on the same menu keeps the liberator out and sits lower.
