Tyramine is a normally occurring monoamine compound and derived traces of amine which come from amino acid. It acts as a noradrenalin, adrenaline releasing agent. Somehow it is unable to cross the blood brain barrel which results in non-psychoactive peripheral sympathomimeric effects. When foods rich in tyramine is taken with monoamine-oxides inhibitor (MOI), it’s caused something famously called the “cheese-effect” or tyramine allergy
Contrary to what most people think, allergies are not the inability of the body to handle a particular stimulus. Rather, it is the hypersensitivity to a stimulus that causes the body to react in its effort to expunge the irritant. It is classified as a disorder afflicting the immune system. Note, it is a disorder, not a deficit. In the case of cheesecake allergies, it is the hypersensitivity to chemicals and substances in the cheese.
