Thanks a lot for your replies everyone, that's very helpful!

People here are basically taught that iodized salt is the best for you because you need iodine. Little do most people know how much more they eat than they need.
Exactly!! It's the same here in Germany, and we have no chance to avoid it as it's everywhere in our food. Most people think it's good for them, but you cannot control how much of it you actually eat. And people who have to avoid it due to certain thyroid conditions, or who react sensitive to iodine really have a problem here.
