Cornstarch
A highly refined starch with virtually no histamine activity — one of the most neutral thickeners available.
Cornstarch is so heavily processed that most of the compounds found in whole corn are stripped away, leaving a very neutral product.
-
Refined and inert — the refining process removes proteins and other components, leaving behind a starch that doesn't trigger histamine release or block breakdown enzymes
-
Common in processed foods — when cornstarch appears as an ingredient in packaged products, the other ingredients in those products are worth checking too
On its own, it's typically a non-issue for histamine-sensitive people.
