Be careful of histamine... is in all fermented foods, veg, fruits, meat, alcohol, vinegar, Kombucha...
Many people in the health food movement are a bit obsessed by fermentation, but also many develop after some time problems related to histamine intolerance. Histamine is a neurotransmitter, important for brain, braking down food, connected with the sleep rhythm. I got hyper, unfocused, sleeping disorders etc, so don't over do it.
Ah, yes, forgot to say: cheese is really bad if you this sensitivity (and all other fermented dairy products). Which makes it hard to consume dairy, as many people cannot tolerate milk.
It's not necessary to go totally histamine-free if you have this problem (kind of hard actually), because we actually really nead it...
