IHOP New England Clam Chowder

High histamine

This clam chowder is high, driven by the seafood-based chowder itself and yeast extract.

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

It is a creamy soup of clams, potatoes, onions, celery, and butter thickened with wheat flour.

  • Clam chowder base — clams and seafood broth carry a lot of histamine, which is the main reason this bowl runs high.

  • Yeast extract and wheat flour — yeast extract is high on its own, and the enriched wheat flour thickener adds moderate weight, while the cream, potatoes, and butter are milder.

Since the clams themselves drive it, a broth-free option is the better choice.
