Doctors will tell you that there is no significant difference between sea salt and mined (regular table) salt, except that mined salt typically has iodine, which is necessary for good thyroid health.
But a recent report stated that there is no reason for drastic cuts in sodium intake, and that there is just as much danger from getting too little salt as too much. This contradicts what doctors, including my own, have been telling us for years.
I don’t really know if sea salt is that much better for you, but it is obvious that it provides many trace minerals. Here is a sea salt site that talks of the benefits of sea salt. Decide for yourself. I’m switching to sea salt because it tastes better, and because if there really is a benefit, I don’t want to miss out. It couldn’t hurt.
