Sea salt does contain some trace minerals, but it is bad to eat. Sea salt is the result of evaporation of seawater that accumulates on the shores of the sea. While sea salt contains some trace minerals, significant amounts of its iodine evaporate due to exposure to open air and sunlight. Therefore, sea salt does not have enough iodine to meet the daily iodine needs of individuals. In addition, sea salt contains various impurities, including heavy metals such as lead, mercury, and arsenic, which have been proven to be carcinogenic. On the other hand, the entry of industrial waste into the sea and oceans is another source of sea salt pollution.
Is sea salt harmful even if it is prepared hygienically?
Answer: If sea salt is hygienically purified in industrial factories and heavy metals and extra minerals are removed, it will be harmless. However, this action alone is not enough, and to compensate for the iodine deficiency, adding iodine salts to the salt is necessary. This purification and iodine addition process means the production of purified iodized salt, which is recommended for consumption. If the salt is taken from rock salt or the sea and is properly purified and iodized, both types of salt will be suitable for desirable consumption.
