I can understand that the refined salts are ubiquitous and therefore require the predominant attentions, but I have a feeling that before too long, refined salt may go the way of such food products as trans-fats.It’s my understanding that whole sea salts are quite rich in balancing minerals such as calcium, magnesium, and potassium. In fact, it has ≈90 different minerals and trace elements compared with table salt, which has 2, sodium and chloride (not including anticaking agents and sometimes iodine). Some whole sea salts have as little as 74% sodium chloride compared with the ≈99% sodium chloride of table salt.The studies performed with the highly refined salt are using something that does not really exist in nature, although it has become the “norm” in food preparation and seasoning. Sea salt and mined salts have to be highly refined to become that which we have come to call table salt. (Some of the byproducts of salt refining are “more valuable” as industrial components such as rocket fuel.) The refining of salt has a relatively short history, and the change over to this highly refined product may be responsible for many diseases that result from the modern diet.Sea salt also has the distinct advantage of tasting a whole lot better than table salt, which tends to taste caustic. The best kind is still moist and has an off-white to gray color. Sea salts that have been refined and overwashed lose a lot of the beneficial minerals and elements and when dried lose their natural iodine. (If you live in landlocked areas, iodine from sea salt is recommended, but coastal dwellers are sometimes discouraged from using regular iodized salt as they get all they need from the airborne trace element.)As you can see, I’ve put some thought into this and, time allowing, would be glad to share more information with interested parties.

There is, however, evidence from animal experiments suggesting that the refined salt is more hypertensionogenic.1 Nevertheless, it is likely that excess salt intake, whether refined or not, will do more harm than good, but the interesting questions raised by Mr Holland deserved attention.
