Sea salt or Kosher salt is chemically treated salt produced by evaporation from seawater. It's commonly used for cooking, seasoning foods, cosmetics, and also for preserving food. It's also known as black salt, coastal salt, or marine salt.
Evaporating sea salt contains a lot of sodium chloride. When it evaporates into the air, the salt goes with it literally. People don't notice a huge difference in taste between freshly-prepared sea salt and ordinary table salt because sea salt's taste goes away on contact. Unfortunately, this characteristic isn't to be missed when it comes to regulating blood pressure. Scientific research has proven that the concentration of salt in a person's blood can affect how much salt in his blood contains.
Sea salt and table salt differ primarily due to the way they undergo evaporation. Sea salt follows the natural process of evaporation, which makes it much slower and less noticeable. On the other hand, table salt goes through more processing to make it available to us in supermarkets and markets.
Evaporated sea salt (with a few exceptions) does contain trace minerals. However, not all trace minerals are beneficial to humans, especially in large amounts. The trace minerals found in seawater are difficult to absorb through human skin. And even if nutrients could be absorbed through human skin, most of these trace minerals would be lost in the chemical process that table salt undergoes.
High blood pressure is a condition that can be controlled. However, the only way to do so is through taking prescribed medications. Salt is definitely less harmful than sodium, but people with high blood pressure should avoid table salt and choose sodium-free alternatives.
Sodium and potassium are found naturally in a wide range of foods. For example, kosher salt, sea salt, and table salt have high mineral contents. In addition to containing these two minerals, evaporating seawater also contains sodium and potassium. But these two elements are lost during the chemical processing of table salt and sea salt.
The only way to get sodium and potassium is through eating healthy foods. However, avoiding table salt altogether is not recommended. It can still be used as an ingredient in cooking. And it is important to know which types of food are higher in sodium than others. People with high blood pressure should limit their sodium consumption. And people with lower blood pressure should opt for low-salt products.
While artificial enhancements to table salt may help increase the number of trace minerals, there is no scientific evidence that these additives improve health. Artificial additives can contribute to environmental pollution. And there is some evidence that they increase the occurrence of hypertension. In addition, sodium contributes to bone loss in aged animals.
There are two types of table salt. One type is typically mined in the US. This type of table salt is more refined and processed. It typically mines saltpans and salt springs. These minerals usually contain some degree of sodium.
The second type of table salt is derived from coastal areas. This type of table salt is typically mined offshore. It does not contain any trace minerals other than sodium. Some companies extract it from seawater.
Companies typically mine coastal areas offshore from Northern California to the Mexican beach resorts. In order to extract it from seawater, the company uses a process called sand lathering. The resulting salt deposits are processed and made into table salt.
However, these types of table salt deposits do not come from natural seawater. Rather, they are typically mined from rock salts that have been trapped under the ocean's bottom. When the salt is wet, it is easy to remove it from the sea bed. This is how most table salt is derived from sea salt deposits.
