Is Subway Artisan Italian Bread High in Histamine?

Subway Artisan Italian Bread

Moderate histamine

This bread is moderate in histamine, driven mostly by the wheat flour and yeast used to leaven 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

It is a simple loaf of wheat flour, water, yeast, sugar, wheat gluten, and salt.

Yeast — the leavening yeast is a moderate driver here, which is typical for a risen bread.
Wheat flour — the flour itself sits at moderate, so together they keep this loaf in the middle rather than low. There are no aged cheeses or cured meats baked in to push it higher.

This is one of the plainer bread choices, so it is a reasonable pick if you are watching histamine.
