When I was growing up I used to eat pineapple and never really noticed anything. My mother never had any in the house but I would eat it at school and so on.
When I was 16 I had eaten fruit cocktail at my school and suffered a severe allergic reaction. After some time I realized it was pineapple that was making me get splotchy and made it hard for me to breathe. After telling my mother of this, she told me pineapple made her nauseous and sometimes vomit. We both have GERD as well.
I avoided pineapple at all costs. Soon I began to get splotchy and have trouble breathing with sweet and spicy foods, BBQ sauce, and fruit punch. When I was 18 I had a severe reaction to Hawaiian Punch.
I now have EPI pens and I have to closely watch out. I am compiling a list of foods which are safe and what may cause a problem.
I have read about pineapple allergies to raw pineapple and such, but I have never found anyone who is hospitalized for pineapple in BBQ sauce like me. Is there anyone who has a problem like this? My doctors are clueless because they haven't seen anything like it.
