Is IHOP Hoagie Roll High in Histamine?

IHOP Hoagie Roll

Moderate histamine

This hoagie roll is moderate, from its flour, yeast, and soybean oil.

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

It is a soft sandwich roll built from wheat flour, wheat gluten, yeast, and a little oil.

Flour and yeast lead it — the flour and the yeast leavening are each moderate, and together they set this roll in the middle range.
Soybean oil adds to it — the soybean oil worked into the dough is also moderate, so the roll lands solidly at moderate rather than low.

A fresh, non-yeasty base would sit lower, but as rolls go this is unremarkable.
