Grana Padano
Long aging allows bacteria to build up significant histamine in this hard Italian cheese.
Grana Padano is aged for at least 9 months, giving bacteria plenty of time to produce histamine from proteins in the milk.
-
Extended aging — the longer a cheese ages, the more histamine accumulates. Grana Padano sits in the same high range as Parmesan and other long-aged Italian hard cheeses.
-
Freshness doesn't help here — unlike some foods where buying fresh lowers histamine, the high levels in aged hard cheese are built into the process itself.
Smaller portions, paired with lower-histamine foods, may help with tolerance.
