Sea Salt

What is sea salt? – Sea salt is a type of salt that is made by evaporating seawater or salt water lakes, unlike regular salt that is taken from sedimentary deposits.1 Sea salt is a popular seasoning in many dishes as it is known for having a coarse texture and strong flavor. For those wondering, does sea salt have iodine in it? Yes, sea salt does contain iodine just like regular table salt, however it contains much less iodine. Most table salt is iodized, which means they add extra iodine into the product during processing.

You may wonder, is sea salt healthy?  Many believe that sea salt contains less sodium than most regular salts however this has been proven to be incorrect. Sea salt nutrition facts show that a ¼ teaspoon of sea salt contains about 575 mg of sodium.

The main difference between these salts is that sea salt is made with very minimal processing, and contains sea salt minerals like magnesium, potassium and calcium.1

It is reported as being one of the rarest types of sea salt on earth because its collection process can only be carried out during certain times of year.
