My aunt is allergic to corn! She can have things with High Fructose Corn Syrup and the like, but things like corn tortillas and such give her an allergic reaction.

I myself am not allergic to anything, but I am very sensitive to certain foods, like candy that is strongly grape or pineapple flavoured or oily tree nus (I love cashews, though). I can't eat doughnuts, certain cookies, or cake unless I'm craving it. All of these foods (plus some others I'm not thinking of) give me bad headaches that progress into strong migraines if I don't treat it with something strong near the beginning. It's even worse if it's hot, if something's on my forehead, or if I'm staring at a screen (I.e. TV, Gameboy, computer...)

My youngest sister is allergic to nectarines. It was way worse when she was younger, though. She would break out into hives all over her face.

My other younger sister has wierd time periods every few years where she's violently lactose intolerant. It usually leaves in a few months, though.

My grandmother (on my mom's side) is (was) lactose intolerant, and so is my father. I find it strange that I'm not.

My grandmother used to drink milk every day when she was younger (teens, I believe) but one day she just woke up and was lactose intolerant. She couldn't have ice cream, or even too much cheese. She was like that for 30-40 years. In the last year or so she hasn't been lactose intolerant at all. It just disappeared, oddly enough.

Another one of my aunts is allergic to tree nuts, but she can have small portions of walnuts.

Whew! That was a fun (long) post. I guess my entire family is weird. O_o
