Intro
Histamine is, what makes your cheeks and ears flush after drinking a few sips of red wine or sect. I also greatly observed it on chocholate, green and black tea, vinegar, cheese, joghurt, soy sauce, yeast, sourdough, sauerkraut or other fermented foods. Histamine grows in stale or reheated foods. It is in eggs, seafood, spinach, tomatoes, tomato sauce, ketchup, eggplant and avocado.

IT’S IN ALMOST EVERYTHING EVERYONE LOVES!!!

Besides of developing a flush, people like I, also develop brain fog, rashes, eczema and runny nose. It makes very tired, sleepy and closed out. Histamine, can be the reason for headache, migraine, diarrhea, dysmenorrhea and a lot of other diseases.
Histamine might also accumulate, if one has a shock or is highly stressed or traumatized. 

As an example: I do develop it if I’m standing in front of a crowd or even just a person and have to give a lecture. My brain just shuts down and I don't remember anything I wanted to say. It's to much attention, information and stress at once.
You can imagine, that some of the things, that nowadays are promoted for developing self–confidence, seem terrible to me. And you can imagine that there are certain jobs/fields I should not work/be in. Even artificial light sources can cause me irritation. But you can also imagine that there are certain jobs/fields, I should work in, because of this kind of awareness.
