Is Jamba Juice Ranch Dressing High in Histamine?

Jamba Juice Ranch Dressing

High histamine

This ranch is high in histamine because it is built on cultured buttermilk and vinegar.

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

This ranch is made from soybean oil, buttermilk, egg yolk, vinegar, and seasonings.

Cultured buttermilk — ranch dressing is high because buttermilk is a fermented dairy, and the culturing process is what builds the histamine up.
Soybean oil and vinegar — the soybean oil adds a moderate layer, and the distilled vinegar sits on top of the already-high buttermilk base.

There is not a clean way to make a cultured-buttermilk ranch low, so a plain oil-based drizzle is the better route.
