Tyramine is a monoamine compound found in foods that have been aged or fermented. High levels of tyramines can also be found in spoiled food. If you are on medication classified as monoamine oxidase inhibitors, also known as MAO-I, eating foods that contain tyramine can cause serious and even fatal reactions. Even consuming as little as 6 to 8 mg of tyramine can increase your blood pressure and heart rate.
