As I understand it the real reason that they iodized salt is nuclear weapons. By overloading a person's body with safe iodine, it prevents the body from picking up radioactive iodine in the event of a nuclear war.
It's actually interesting, a lot of our food has been corrupted by Total War. It isn't just about salt and sugar and fat, there are military technologies designed to help produce shelf-stable rations that food company is routinely use in their standard foodstuffs because it ensures that that food is shelf stable a lot longer. You can really see the difference between industrially produced bread or the bread made at the local bakery (or in your own oven). The industrially produced bread lasts forever, but the local bread or the bread that you make in your own house has a very short shelf life before the fact that it is food means that stuff like mold starts to grow.
