Is IHOP Ham High in Histamine?

IHOP Ham

High histamine

Ham is high in histamine because it is a cured, nitrite-preserved pork.

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 a slice of cured ham made from pork with salt, dextrose, and curing agents.

Curing drives it — ham is cured and preserved, and cured meats carry a high histamine load, which is what puts this at the top of the range.
Sodium nitrite adds to it — the sodium nitrite used to preserve the pork is itself a high driver, so the curing shows up twice over.

Cured meats are one of the harder items to bring down, so a fresh protein is the better route.
