Are Panera Bread Croissant Croutons High in Histamine?

Panera Bread Croissant Croutons

Moderate histamine

These croissant croutons are moderate, driven by the enriched flour, margarine, yeast, and vinegar.

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.

Dairy Gluten

These are baked croissant pieces made from enriched flour, margarine, sugar, and yeast.

Several moderate ingredients together — the enriched flour, yeast, and a touch of vinegar each sit at moderate, and combined they set the croutons at a moderate level.
Margarine adds to it — the margarine here also lands moderate, so it nudges the level along with the flour and yeast rather than the fresh butter you might expect in a croissant.

If you want a lower-histamine salad, ask for it without the croutons and add a fresh crunchy vegetable instead.
