Is Sonic Hot Dog Bun, Footlong High in Histamine?

Sonic Hot Dog Bun, Footlong

Moderate histamine

A Sonic footlong hot dog bun is moderate in histamine, from the enriched flour, yeast, and soybean oil.

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

This is a long soft roll made from unbleached enriched flour, yeast, wheat gluten, soybean oil, and a bit of sesame flour.

Enriched flour and yeast — it is a yeast-raised enriched-wheat bun, and both the flour and the yeast sit at a moderate level, which is what puts it in the middle.
Soybean oil — the soybean oil in the dough also runs moderate, adding to the picture rather than sitting neutral.

The bun itself stays in the moderate range, so the fresher and simpler your fillings, the better the whole thing sits.
