Parmesan Intolerance Check
Full breakdown across 16 food intolerance detectors.
Known trigger for some intolerances
Flagged Intolerances
Aged 12+ months, histamine concentration increases steadily with maturation time.
Parmesan is one of the most histamine-rich foods because of how long it ages. As the cheese matures, bacteria break milk proteins down into amino acids, and the amino acid histidine is converted into histamine. The longer the ageing, the more builds up.
A true Parmigiano-Reggiano ages a minimum of 12 months, often 24 to 36, so histamine keeps accumulating the whole time. There is no low-histamine version of a long-aged hard cheese, because the age is the point. Younger, fresher cheeses sit far lower on the scale.
Rated very high (dose-score 3) in the histamine detector, alongside other long-aged cheeses and cured foods.
Contains casein and whey; very high in concentrated milk proteins per gram.
One of the highest tyramine foods; bacterial cultures produce it during long ageing.
Reaction worse before your period?
If Parmesan triggers symptoms more in the second half of your cycle, that is a histamine + oestrogen interaction, not a simple food trigger. Here's what's happening biochemically.
