Are you allergic to latex? They can go hand in hand. Pineapple would be rash, itchiness, diarrhea, vomiting, low blood pressure problems breathing. Kiwi us similar but can have abdominal problems as well. See your doctor to get tested. Good luck
If you think you are allergic to pineapple or kiwi, try making sure that you don't get a rash from eating it, or smelling it. if a rash, bumps, or another allergic reaction occurs, then you will know that you are allergic to them.
Why do you think you may be allergic? It can be very dangerous to be allergic to foods (and insects). Anaphylactic shock is when the throat starts to swell and close up. Your face, eyes and lips may swell as well. You must always carry an Epi-pen if you have ever had this reaction!
If you eat some and have an allergic reaction (rash, hives, swelling, difficulty breathing, congestion, and/or itching), you'll know. If you are allergic, you should avoid it because an allergic reaction can get stronger with repeated exposure.
