Iodised salt
The healthier salt is iodised; but the sea salt can be also iodised.
Iodised salt (sodium chloride) contain iodine (as potassium/sodium iodide or potassium/sodium iodate). The concentration of iodine is 20 +/- 5 mg/kg. Iodised salt is recommended to avoid idiocy.
Iodised table salt contain sodium chloride, potassium iodide (or iodate) and anticaking substances.
NO !!

Iodised salt is considered a mixture because it consists of two components: regular table salt (sodium chloride) and an added iodine compound, typically potassium iodide or potassium iodate. These components retain their individual properties and can be present in varying proportions. Thus, iodised salt does not have a uniform composition throughout, which is characteristic of mixtures.
Thankfully it is now very easy to get non-iodised salt at local grocery chains. Brands like Kroger, Harveys, and Publix all have store brand non-iodised salt. Lawreys and Morton also sell a non-iodised salt on their website.

Iodised salt contains a very small amount of iodine added to prevent iodine deficiency. When heated during cooking, the iodine content in iodised salt does not vaporize or sublimate significantly to create a health concern. Hence, the amount of iodine present in the food after cooking from iodised salt is negligible and safe.
KFC use fine iodised sodium chloride.
It is iodised so it flows easier and does not stick in clumps
