Hazelnuts
Hazelnuts are listed by some sources as potential histamine liberators, though this isn't consistent across major references like SIGHI.
Like many tree nuts, hazelnuts are thought by some sources to act as histamine liberators rather than containing large amounts of histamine themselves, though major references like SIGHI rate them as well-tolerated.
-
Histamine liberation — they appear on some histamine intolerance food lists as foods that may trigger the body to release stored histamine, which is why reactions can feel disproportionate to the amount eaten
-
Common pairings — hazelnuts frequently appear with chocolate and cocoa in products like spreads, both of which are also histamine liberators, making those combinations particularly worth noting
Plain hazelnuts are easier to assess on their own than when they appear in processed products.
