Why do Apples and Other Fruits Make My Mouth Itch?

Wow doesn't the fruit in the farmers markets and grocery stores look delicious?  It's such a treat to see fresh cherries, nectarines, and peaches.  But for many, biting into these fruits can make their mouth and lips itch! In some cases, small blisters might form. Bizarre right?  And isn't it funny that they can eat them when they are cooked or peeled? 



So what's going on?  Can you really be allergic to raw fruit?  Yes!


Why do Apples and Other Fruits Make My Mouth Itch?

• This is a common problem called oral allergy syndrome. 
•  People allergic to raw fruits are most likely also allergic to tree or weed pollens.
• The protein that causes the allergy is heat sensitive.  Heating it changes it so that it doesn't cause a reaction.
• Many people think it's the pesticides on the fruit that causes the itching. 
• Actually the protein is also present on many tree fruits and nuts.  Apple being the most common offender, but any of the stone fruits (cherries, plums, nectarines, and peaches) and other "tree" fruits like pears can cause the problem.
