suggested replacement is pollock, which does contain iodine. If the list you provided includes food you eat in the right quantity to get enough iodine every day then you would be OK. But read the label of your bread. The one I've always bought does not list iodine nor does some of the other brands I inspected. Same with cereal, yogurt and cheese. Being that iodine has its own designation on the Periodic Table, it should be listed if included. Instead it's just sodium. Sometimes ingredients are not listed if too low in quantity, but I notice that potassium gets listed when it's added to food and that's something we don't need everyday, so why don't they list iodine even if low in quantity????
I was going to be contacting some manufacturers and posing the question to them about whether they use iodized salt in their manufacturing process. I don't expect an answer, however, but will post any answer(s) I receive.
As for eating seaweed, yuck, but I don't like sushi either!
