Allergic to Fruits and Vegetables?

Who would think that delicious fruit or vegetables could cause anyone any trouble?

I listed numerous food allergies but found out about a new one -- one I do not have.  Allergies to some fruits and vegetables.  I was sitting with my cousin and found out she was allergic to pineapple and experienced something similar to anaphylaxis when she ate it.  I was surprised.  I had heard of oral allergies before from other members of my family.  The allergy was just a tickle in the throat once a raw piece of fruit or vegetable was eaten.  The less ripe the fruit or vegetable the stronger the reaction. I did some research and found a good article explaining the effect fruits and vegetables can have on someone who has an allergy.  Below is the link to the article.
