I have gotten to the point where I don't often think about my allergies a whole lot until someone feels bad for me that I miss out on all these foods..... then ah, what I would do to eat some fresh fruit again.
I have what is termed in the medical world Oral Allergy Syndrome.... and let me tell you, it sucks.
My particular bane is birch pollen, which means I can't eat so many of the fresh fruit most people take for granted in my area. Peaches, apples, cherries, plums, kiwis, carrots, parsnips, and many others and some, like pears and celery that have the same protien that I just haven't reacted to yet.
The human immune system is a wonderous thing indeed, there are so many things that it does and functions perfectly at, while there are some where you just have to say... "what is wrong with you!"
