How is Salt Made??
Today there are two main methods for obtaining salt, evaporation from sea water and mining salt from the earth. Most common table salts and salts used for industrial purposes are obtained through mining, while specialty or gourmet salts are still produced via evaporation of sea water.

This was because their soil levels were extremely low in iodine, and people weren’t eating iodine rich foods
