Amazingly, Velveeta, the poster child for processed food, contains no soy.
Here’s the wikipedia article, I’d rather post from velveeta’s own site, but this will do for now:
I'm trying to track allergen information for every restaurant that we eat at. With my son's soy allergy, each time we eat at a restaurant, it can take up to 30 minutes to figure out what he can eat. Especially since most restaurants don't accurately represent their usage of soy.
We're tracking what soy free (including soybean oil free) foods our son can eat at all restaurants we go to. If you've got a soy allergy in your family and have any information you can share, please contact us.
