Cucumber (fresh)
UnloadedSterilized cucumber
Fermentation can increase histamine content.
Caution
May cause symptoms in more sensitive people. Track your own reaction.
Sterilized cucumbers are pickled in vinegar, which itself can irritate or block the DAO enzyme. However, if the cucumbers are fermented, the histamine content in them increases dramatically due to the activity of bacteria. Caution is therefore necessary with HIT for both variants, but fermented ones are more risky.
