Is Papa Murphy's Shredded Parmesan Cheese High in Histamine?

Papa Murphy's Shredded Parmesan Cheese

High histamine

This parmesan topping is high in histamine because parmesan is a long-aged hard cheese.

This is sold raw and you bake it at home, which is the freshest case on this whole list. Nothing sits in a warmer, and you control how long it waits between the shop and the oven. Refrigerate it as soon as you get home and bake it the same day, because histamine builds up as protein foods sit whether that happens in a kitchen or in your fridge.

Dairy

This is shredded parmesan made from pasteurized milk, cheese culture, salt, and enzymes.

Long-aged parmesan — parmesan is aged for a long time, and that maturing is exactly what makes it high in histamine.
The rest is mild — the milk and salt are quiet, but the aged parmesan sets the level by itself.

A fresh cheese is a much gentler choice here.
