Jeepers; just found this out - Avocados and bananas contain high concentrations of tyrosine and should not be eaten when over-ripe by people who are tyramine intolerant.... "Tyramine is a compound that is produced when the tyrosine in tyrosine-containing foods breaks down over time. The amount of tyramine in a product increases significantly when the food is fermented, over-ripe or aged. For some people, foods containing a high concentration of tyramine can trigger intolerance symptoms that include bloating, diarrhea, nausea and stomach pain. Food intolerances are not caused by an abnormal immune response, but by a negative physiological reaction to a component in the food, according to a review published by the Oxford Journals.
TYRAMINE INTOLERANCE TREATMENT:
To prevent the bloating associated with tyramine intolerance, doctors advise avoiding foods that have a high tyramine content, as well as over-ripe foods that contain large amounts of tyrosine. Tyramine-rich foods include aged, dried, pickled or smoked meats and fish such as salami, pepperoni or pickled herring; alcoholic drinks such as ale, beer, vermouth or burgundy; fermented soy products such as soy or teriyaki sauce; all types of nuts; and any aged cheeses such as blue cheese, brie or mozzarella..." & of course the above mentioned bananas & avocados http://www.livestrong.com/article/554406-tyrosine-bloating/
