Is Sonic Peach Zero-Sugar Syrup High in Histamine?

Sonic Peach Zero-Sugar Syrup

Low histamine

Sonic's peach zero-sugar syrup is low in histamine, a simple flavoring base.

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.

This is a light flavor syrup made from citric acid, cellulose gum, sucralose, beta carotene, and silicone.

No histamine drivers — none of these ingredients carry meaningful histamine, so this syrup sits comfortably at a low level.
Flavor and texture only — the sucralose sweetens, the cellulose gum thickens, and the beta carotene tints, none of which raise the level.

This is an easy add to a drink when you want peach flavor kept simple.
