Are Jimmy John's Mini Croutons High in Histamine?

Jimmy John's Mini Croutons

Moderate histamine

These baked croutons are moderate because of the wheat flour, malted barley, and yeast.

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

Small toasted bread cubes made from wheat flour, malted barley flour, canola and sunflower oil, salt, and yeast.

Wheat and malted barley flour — both sit at a moderate level, and they are the backbone of the crouton, so they set the tone here.
Yeast — the leavening also lands at moderate, which keeps these in the same range rather than low.

They are a moderate topping, so leaving them off a salad is an easy way to lighten the plate.
