Is Panera Bread Classic White Loaf High in Histamine?

Panera Bread Classic White Loaf

Moderate histamine

This white loaf is moderate, driven by the American cheese and annatto coloring.

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 Dairy

This is a classic white miche layered with processed yellow American cheese, cream, and a little coloring.

Pasteurized process American cheese — the processed cheese lands moderate, which is the main thing lifting this above a plain loaf.
Annatto and paprika coloring — the added coloring also runs moderate, nudging the overall rating up alongside the cheese.

The white bread itself is a fresh base and not what drives the number; a plain loaf without the cheese layer would sit lower.
