tyramine is not metabolized by mao-A. RIMA's like harmine and harmaline only inhibit mao-A and only mao-B at high doses..and even then tyramine will easily outcompete harmine or harmaline for the mao-B..the whole tyramine thing is not to worry about really..so yeah you can eat meat etc.
What you have to worry about is other stimulants like caffine etc..many other psychoactive substances interact with harmalas..and many foods contain stimulants etc so be aware of what spices and herbs you are eating durring that time.
Beans and salsa are fine for me.
Avoid cured/smoked meats etc if you are worried about tyramine still..some chicken/fish has been fine for me.
Avoid caffine directly before and after..might want to hold off on cannabis also for your first few times at least.
Fruits and veggies are fine..grapefruit may have some kind of interaction going on I am not entirely sure about that one..same with pomegranite juice..they wont hurt you though, they might just have some weird synergy.
Rice, fruits, veggies, beans, some chicken etc..thats all okay.
Long live the unwoke.
