Is IHOP Grilled Buttermilk Biscuit High in Histamine?

IHOP Grilled Buttermilk Biscuit

High histamine

This biscuit is high in histamine, mostly from the buttermilk baked into it.

Most of this is cooked to order, which is the best case for histamine. Even so, a restaurant kitchen preps ahead and holds things warm through a service, so freshness varies more than it would at home. The rating above comes from the chain's published ingredients. If a dish is borderline for you, asking how it is prepared tells you more than the menu does.

Dairy Gluten

A grilled buttermilk biscuit is a soft, flaky bread built from flour, palm and soybean oil, and buttermilk.

Buttermilk leads it — buttermilk is a cultured dairy, and that fermentation is what pushes the whole biscuit into high territory.
The flour and oils add to it — the enriched bleached flour, modified wheat starch, and soybean oil each land in the moderate range, so even setting the buttermilk aside the base is not a clean low.

There is no easy tweak here since the buttermilk is baked in, so a plain lower-histamine side is the smarter call.
