Sea salt is seawater salt that has been extracted from evaporated seawater. It's most common use is as cooking salt or seasoning in cooking, baking, cosmetics, and even for preserving food. It's also known as black kosher salt or rock salt. Sea salt was first mined from fossilized marine corals millions of years ago.
Like table salt, it's naturally occurring. But it's also one of the world's largest importers. Since it's so easy and inexpensive to ship worldwide, it's shipped all over the world. From its beginnings on a remote island in the Pacific to its current popularity as a kitchen ingredient, kosher salt comes from everywhere even the United States.
Most sea salt used on land comes from countries with sandy soils and rich deposits of calcium carbonate. The places where seawater is drained have little or no trace of these natural minerals. In order to increase the amount of magnesium and sodium in table salt or as a recipe ingredient, manufacturers extract these minerals from seawater, then ship it all over the world. While the process can be crude and may not be healthy, it's much easier than mining the country's depleted deposits.
Global sea salt imports have helped keep global iodine supplies stable. Because there are only a few purest deposits, it's difficult to get them. Some countries, like the United States, are trying to increase their imports of iodine and other trace minerals. But the problem is that it's difficult to monitor the levels of these minerals in seawater, which is why it's so hard to find a dependable source of iodine. In the United States, iodine content usually varies between states.
Because some people are iodine poor, sea salt helps. High amounts of calcium and potassium may prevent hypothyroidism from happening. It's been proven that a person with a deficiency of both essential minerals calcium and potassium, does not digest enough food in order to maintain regular bodily functions. Sea salt seems to help, because of its extremely high levels of iodine and sodium.
Salt is processed differently in different parts of the world. Certain countries, such as the United States, have more regulations regarding the ways table salt and other sea salts are processed. For example, many are less sodium than traditional sea salt is since it has to go through more alteration to make it less sticky and therefore less likely to form lard. Processed table salt also doesn't contain as much iodine, as it does when it comes from springs and rivers.
Iodine intake is important because this mineral is a major source of maintaining thyroid function. High amounts of iodine have been linked with developmental problems, including hyperthyroidism and even cancer. People who get too little iodine don't get enough of the other minerals and essential nutrients that they need, so switching to sea salt instead of refined table salt can benefit your health by increasing iodine intake and balancing your mineral levels.
Salt crystals are different from regular table salt in many ways. You might think that crystal salt is coarse and does more harm to the body than regular table salt. Actually, sea salts have fewer crystals than regular table salt and the fewer crystals there are, the more concentrated the nutrient is. Crystal salt is a powerful antioxidant, helping to rid the body of harmful free radicals, which have been linked with age and various diseases.
Crystal salt is also a powerful detoxifier. Studies have shown that salt crystals help to reduce the buildup of heavy metals like lead in the bloodstream. This is because the salt contains large amounts of iodine, which is a natural disinfectant. The fewer crystals you find in sea salt, the less iodine there is, which means it's more difficult for the body to eliminate toxins. If you need to lower your blood pressure, add sea salt to your diet to help remove those heavy metals out of your system.
The main thing to remember about sea salt is that it is naturally full of minerals, like table salt, but without the additives and unnecessary chemicals that we've become accustomed to in our food. The world is getting less natural, less processed, and more polluted by the day, and we're not getting any healthier. Making sure that you're getting as many natural nutrients as possible is a good way to ensure that your body's systems work as best as they can. Sodium chloride is one of the easiest ways to do that.
Of course, sodium isn't the only mineral that we need to keep us healthy. Calcium, for instance, is necessary for strong bones. But when you cook food with high levels of sodium chloride, it can actually take the calcium out of the food. So, if you want to ensure that you get plenty of calcium from your sea salt and you should make sure that you eat plenty of unprocessed seawater, as well as a variety of other fruits and vegetables. It's the simplest, most effective way to get your daily calcium requirements met.
