I am also allergic to soy. I do not notice any symptoms when I eat it, but I tested allergic. I am allergic to peanuts and carry an epi-pen for that. Again have never had a reaction and had no idea I was allergic to any of this stuff before being tested. You should know that almost all fresh produce is waxed with a soy based product. This is to help slow the liquid from drying up out of the fruit so it stays good longer. You should wash (meaning *really* scrub these with hot water and soap) before eating or peeling. Apples, cucumbers and peppers come to mind right off. Also most newspaper ink is soy based so touching that and then touching your skin could make you itch. I am sure cosmetics have soy, most of them have corn, if that bothers you. Of course I can't tolerate the fragrance in most of these products anyway.
soy is another product similar to corn that is hidden in just about everything. Like corn I am sure it has a dozen fancy names and even after reading a label you still don't know what's in it! I have had to do a lot of research.
People get a strange look on their face when I tell them I am allergic to corn so I cannot drink soda. Really, what do people think soda is? Same with ice cream, it's corn. I read an ice cream label recently at Walmart that said "natural" on the front. The ingredients list corn syrup. Since when is corn syrup natural? I don't understand that.
