Is Culver's Boston Clam Chowder Soup High in Histamine?

Culver's Boston Clam Chowder Soup

High histamine

This clam chowder is high in histamine, driven by the clams, soy, and long-simmered 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.

Dairy Gluten Histamine Liberator

This is a creamy potato and clam soup with celery, margarine, and a flour thickener, and the seafood-and-soy combination sets the rating.

Clam chowder base and soy — clams and the soy in the mix both run high, and soups like this that are cooked and held tend to sit at the high end.
Flour and margarine — the enriched wheat flour and margarine land in the moderate range, adding to the load rather than driving it.

If you want something lower on the same menu, a simpler broth-free option without the clams and soy is the better route.
