Is Jimmy John's Wheat Sub Bread High in Histamine?

Jimmy John's Wheat Sub Bread

High histamine

This wheat sub bread is high, driven mainly by the sunflower seeds baked into it.

Food here is usually assembled to order from components that were prepped earlier in the day, so it tends to be fresher than a drive-through and less fresh than cooking at home. Histamine builds up as protein foods sit, so how long the chicken or beef has been in the warmer matters as much as what is in the bowl. Treat the rating above as a starting point.

Gluten

A hearty loaf of wheat and whole wheat flour with rye flour, yeast, and sunflower seeds.

Sunflower seeds — these are high on their own, and they push the whole loaf up to high regardless of the rest.
The flour blend — the wheat flour, malted barley flour, rye flour, and yeast each land moderate, so even without the seeds this bread would run higher than a plain white loaf.

If you want a milder base from the same menu, the plain French bread is the gentler pick.
