Just a little anecdote about why tyramine can cause a hypertensive crisis:
In humans, if monoamine metabolism is compromised by the use of monoamine oxidase inhibitors (MAOIs) and foods high in tyramine are ingested, a hypertensive crisis can result as tyramine can cause the release of stored monoamines, such as dopamine, norepinephrine, epinephrine. The first signs of this were discovered by a neurologist who noticed his wife, who at the time was on MAOI medication, had severe headaches when eating cheese. For this reason, the crisis is still called the "cheese syndrome," even though other foods can cause the same problem.Foods high in tyramine include cheese, wine, many meats, chocolate and soy. So yea, basically everything has tyramine in it. Good luck, people on MAO inhibitors.
