< Liver (and maybe other organ meats as well) are high in Tyramine, a known

I think tyramine may not be present in fresh liver.  Liver seems to be the
first thing eaten by hunters, perhaps for this reason.
Also i think if we cook it the tyramine is rendered inactive, though we
would
have to check that.  i know i can take cooked cheese without problems
whereas raw cheese is risky.
