from wikipedia:
Because sea salt generally lacks high concentrations of
iodine, an ion essential for human health
[1], it is not necessarily a healthy substitute for regular iodized table salt, which is usually supplemented with the element, unless another source of dietary iodine is available. Iodized forms of sea salt are now marketed to address this concern.
**** sea salt lacks iodine (I was mistaken). Sea food has lot's of it. So if one does not eat sea food regularly, iodized table salt is a good idea ****
