No, but we eat a lot of seaweed. It's high in iodine, probably too high. Also, unless you cook every single thing from scratch you will get iodine from processed foods. Not just junk food- there is salt in cereal, bread, tomato sauce.. Lots of basic staples used by most ordinary people.

(I might be slightly more cautious about making sure to get enough if you're pregnant because your needs go up a bit).
