Is Sonic Asian-Style Sweet Chili High in Histamine?

Sonic Asian-Style Sweet Chili

High histamine

Sonic sweet chili sauce is high in histamine from soy sauce, soybean paste, and salted sake.

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 Gluten DAO Blocker

This is a sweet-and-savory dipping sauce built on corn syrup, sugar, soy sauce, vinegar, and fermented seasonings.

Soy sauce, fermented soybean paste, salted sake, and yeast extract — these are all fermented or high ingredients, and the sake also blocks the DAO enzyme, so several drivers each land it high.
The supporting flavors — the sweet chili base, paprika, and rice vinegar sit at moderate, but the fermented items above are what set the level.

This sauce has no clean tweak, so plain mustard is a much lower-histamine dip.
