Idahoan Instant Mashed Potatoes
These instant mashed potatoes are high in histamine because of the aged cheddar cheese.
This is dried potato flakes with butter, whey, and cheese seasoning, and the cheese is the issue.
-
Cheddar cheese leads — cheddar is an aged cheese, and aging builds histamine, so it carries the whole product up on its own.
-
The rest is milder — the potatoes, whey, and butter are gentle fresh-dairy and starch ingredients, and only the onion powder and garlic powder add a moderate note.
A plain instant mash without the cheese blend, or fresh potatoes mashed with butter, sits much lower.
