Is IHOP Garlic Bread High in Histamine?

IHOP Garlic Bread

High histamine

IHOP garlic bread is high in histamine, driven by the vegetable protein and buttermilk.

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.

This is an enriched-wheat loaf with garlic, onion, and butter notes, plus added protein and buttermilk.

Vegetable protein and sweet cream buttermilk — these are the high drivers here, and either one is enough to set the level.
The wheat base — enriched wheat flour, yeast, soybean oil, and malted barley flour all sit at moderate, layering under the high items.

There is no clean tweak that drops every driver here, so a fresh, plain bread side would be the better lower-histamine choice.
