Histamine Tracker
Hard cheese (aged)
Aging is the key factor — the longer any hard cheese matures, the more histamine bacteria have time to produce.
As hard cheese ages, bacteria steadily convert the amino acid histidine into histamine — it's a natural part of the process.
-
Time equals accumulation — a cheese aged 12 months will typically contain more histamine than the same cheese aged 3 months, simply because the process has had longer to run.
-
Texture is a useful clue — the harder and drier a cheese feels, the more aged it likely is, and the higher its histamine content tends to be.
Soft, fresh cheeses are generally a more comfortable option for those watching histamine intake.
