I have minor allergies to all sorts of things (mostly medicines....probably due to how many times I had to use antibiotics when little so now I break out in minor hives to some of them...it also may be the die used in the pills). I think I may have one minor food allergy, though I am not sure to what, but until it becomes serious, I am not going to stop eating food I like. I am worried it is dairy, so that is why I try to remain in the dark about it.
I think chemicals etc. have a lot to do with allergies, as well as overexposure to stuff.
That is why my dad, who did beekeeping as a hobby when real young, is deadly allergic to bees now, whereas when he first started, they did not bother him at all.
er...."dye," not "die."
