Sea salt, also known as bay salt, is produced by the process of evaporation of salt water bodies. It is darker in color as compared to refined salt due to the absorption of essential minerals from the clay lining of the body of water. Normally, the harvesting of refined table salt involves heavy processing, including mining followed by iodizing, bleaching, and diluting with anti-caking agents. More chemicals are added during the processing of salt, which often steals all of its beneficial minerals and trace elements, except sodium and chloride.
Unlike refined salts, the preparation of sea salt usually includes very little processing, so it retains its moisture and mineral treasure. These minerals are present in a form that is easily utilized and absorbed by the human body. The climate and the geographical location of the region also play a significant role in the quality and combination of minerals offered by the sea salt.
