Dietary restrictions that should be observed when a patient is receiving monoamine oxidase inhibitor(MAOI)therapy, Alcoholic Beverages,Banana peels,BeanCurd,Fava Bean Pods,Smoked Herring,Pickled Fish, Caviar,Ginseng,Protein Extracts,NON-fresh meat or Liver,Sausage,Bologna,Pepperoni,Salami,Sauerkraut,Shrimp Paste,....Cured Ham is O.K.,Yeast,(Yeast used in Baking is O.K.),.....Raspberries contain TYRAMINE, and small amounts are expected to be safe....Blueberries were not on the list of foods with HIGH LEVELS of TYRAMINE.

I wonder if the biochemical content of blueberries changes with cooking. Overripening of some fruits changes the biochemical content so that tyramine is created or released. Can heat or the addition of sugar with heat change the biochemistry of blueberries and create tyramine.
