IHOP Buttermilk Crispy Chicken Sandwich

High histamine

This crispy chicken sandwich stacks buttermilk-breaded chicken on a bun, and several ingredients push it high.

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 Histamine Liberator

The chicken breast itself is fine, but the breading, seasoning, and bun bring the histamine up.

  • Buttermilk powder, yeast extract, and wheat starch with chicken broth — these are the main high drivers, with the yeast extract and broth-based seasonings being the sort of concentrated flavorings that run high.

  • Breading and bun — the wheat flour breading and the yeasted bun each add moderate levels on top, so the sandwich is high from multiple parts, not just one.

A plainer grilled chicken option without the breaded coating and bun would be much lower.
