Is Panera Bread Rocky Road Syrup High in Histamine?

Panera Bread Rocky Road Syrup

Low histamine

This rocky road syrup is low in histamine, made mostly of sugar and glycerin.

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.

This is a flavoring syrup built from sugar, glycerin, salt, citric acid, and caramelized sugar syrup.

Nothing flagged — none of these ingredients are histamine drivers, so the syrup sits comfortably at the low end.
Simple sweetener base — the citric acid here is a small acidulant, not a citrus fruit, so it does not act as a liberator the way lemon or lime would.

This is an easy pick when you want a flavored drink without the histamine load.
