Is Noodles & Company Cajun Alfredo Sauce High in Histamine?

Noodles & Company Cajun Alfredo Sauce

High histamine

This alfredo is high in histamine from aged parmesan, yeast extract, and balsamic 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

A creamy alfredo whose cream base is fine, but several aged and concentrated add-ins push it up.

Aged cheeses and yeast extract — parmigiano reggiano is aged and high, and autolyzed yeast extract is high as well, both driving the sauce upward.
Vinegar and peppers — balsamic vinegar is high, while roasted red bell peppers and paprika add moderate load on top of the cheese.

The heavy cream itself is gentle, but the cheeses and vinegar set the level here.
