I can answer that one, DMark.
As a kid, I was allergic to so many foodstuffs that it’s a wonder my parents found anything to feed me at all. The list:
Corn (and all corn products, including corn syrup and the like), Wheat (and all wheat products), Chocolate (which has corn syrup in it anyway, so…), Mushrooms, Eggs (and consequently everything with eggs in it) and cow’s milk.
I outgrew the allergy to milk and eggs by kindergarten, the allergies to corn, wheat and their products by early elementary school and the allergy to chocolate in my middle teens. I am still allergic to mushrooms and probably always will be.
The allergist (special allergy doctor) who originally diagnosed my allergies tested me on a twice yearly basis (with these horrible “scratch tests” involving needle pricks on the back) to determine if I was still allergic to those specific foods. He also checked to see if I had developed any new allergies.
Food allergies tend to run in families, just as environmental ones do. My younger half-brother was allergic to all of the things I was, but was also allergic to a host of other foods. Like:
Pork, Beef, Red Food Coloring and Coconut .
He outgrew most of those by late elementary school. At 21, he is still allergic to coconut and is mildly lactose intolerant.
So, yes, thank Og- You can outgrow food allergies. Otherwise, I’d still be sustained on rice cakes and carob. Yuck.
