Pepperoni
Pepperoni is a fermented, dried sausage — fermentation and long curing are two of the biggest drivers of high histamine in cured meats.
The fermentation and drying process that gives pepperoni its flavor is exactly what drives histamine levels up.
-
Fermentation — bacteria present during production convert histidine, a specific amino acid, into histamine through a process called decarboxylation, a natural byproduct of microbial activity
-
Compared to fresh meats — fresh pork or chicken contain far less histamine because they haven't undergone the same microbial activity; pepperoni is essentially at the opposite end of that spectrum
Pepperoni is one of the higher-histamine items in the cured meat category, so even small amounts may be enough to notice a reaction.
