Are Sonic Graham Crumbs High in Histamine?

Sonic Graham Crumbs

Moderate histamine

Graham crumbs are moderate in histamine, from the wheat flour base.

Fast food is cooked in batches and held warm rather than made when you order it, so it is rarely as fresh as something cooked at home. That matters here because histamine builds up as protein foods sit, which means the same item can affect you differently depending on how long it waited.

Gluten

These are crumbled graham topping made from enriched wheat flour, sugar, palm oil, graham flour, brown sugar, and honey.

Enriched wheat flour — this is the one moderate driver here, which keeps the crumbs in the middle range rather than low.
The rest is milder — the sugars, palm oil, and honey do not add much on their own, so the flour is really what sets the level.

If you want a lower-histamine topping, a fruit-based syrup skips the wheat entirely.
