There is a lot of hype out there about sea salt right now. Some of it is true and some of it is not. The truth is that you typical white sea salt is really no better than your traditional white table salt. In fact, it may be less beneficial as it doesn’t have the iodine. Iodine is a trace mineral that is normally part of sea salt. The iodine, as well as all of the other trace minerals that are part of natural sea salt, provide added health benefits to the salt. In white sea salt, all of these trace minerals are stripped from the salt. Natural sea salt still has all of these trace minerals, and it also has color. These colors may very drastically, but typically they are pink or a light grey. So when your sea salt has color, and these natural trace minerals, it is far healthier than table salt as these trace minerals all have added health functions. These trace minerals include things like iodine, magnesium, calcium, chromium and copper (to name a few). Many of them are important for optimal metabolic function and weight loss. Iodine for instance is necessary to make thyroid hormone, whereas magnesium and chromium are needed for utilizing sugar and fat for energy. Zinc and magnesium are both needed for testosterone and adrenal hormone production. And the list goes on.
What about purity? There is a lot of talk about contaminants in the oceans. Near coastal regions of industrial countries, this may be true. However, all in all, the world’s oceans are relatively clean. The simplest reason is dilution and that the organisms near the coastline tend to absorb much of this. The salt mined from beneath the earth is likely to initially have slightly less contaminants before being mined, but once you introduce explosives and/or combustion powered machinery that is no longer the case.
So in short, you just want a sea salt that has some color to it. It does not have to be harvested from 20,000 feet below the earth’s surface by yogi’s that meditate 22 hours a day and mine with an ice pick and a hammer. It just has to have some color. Celtic sea salt is a good, inexpensive option, but there are plenty of other good options as well.
