IHOP Grilled Chicken Sandwich

High histamine

This sandwich is high in histamine, largely from the vegetable protein in the bun and fillings.

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.

Gluten Histamine Liberator

It is a grilled chicken breast on an enriched, yeasted roll with added starches and vegetable protein.

  • Vegetable protein leads it — the added vegetable protein sits in the high range and is the main reason the whole sandwich rates high.

  • The bun stacks up too — the enriched flour, yeast, and soybean oil in the roll are each moderate, so even the base is not clean, on top of the high protein driver.

The chicken alone is far calmer than the assembled sandwich.
