Table salt is a type of salt manufactured by the evaporation process of seawater. It's commonly used for seasoning cooking, baking, cosmetics, and even for preserving food. It's also known as kosher salt, sun salt, or marine salt. Its manufacture is dated back to prehistoric times when people first learned how to evaporate water. Evaporated water contains molecules of salt which have been separated from the surrounding atmosphere.
It's not just necessary for table salt to taste good though. Scientific research has shown that high blood pressure can be brought on by excess sodium intake. This is because salt raises the amount of water in our bodies, making it harder for our organs to efficiently process food. It can also make our cells more permeable, permitting cholesterol to pass through them instead of being absorbed, which can increase the buildup of plaques that lead to heart disease.
There are two main differences between table salt and kosher salt. The main differences come from, how they are processed and what they contain. Sea salt comes directly from the sea and does not need to be processed at all. It retains much of its original texture, including its mineral content like iron, magnesium, calcium, manganese, and sodium.
Many people believe table salt is less expensive than sea salt because it does not have to undergo any processing. However, there are several processing methods used for sea salt which can increase its price. These include passing it through an ocean acidification machine and undergoing high heat treatment, both of which can reduce the concentration of sodium and result in salt with less volume and a lower quality texture.
On the other hand, table salt actually has to go through a series of different processes. Natural salt mines often mine their own natural salt by boiling the rock and then straining it until it can be drained. Most table salt comes from areas that are salty in nature, and these come directly from the sea. It also has to undergo numerous other chemical processes and be enriched with various minerals such as potassium, magnesium, zinc, and sodium.
So which is better? Each has its own main differences, but the bottom line is that they both are healthy alternatives to salt. Of course, if you're on a low-salt diet you should avoid table salt entirely, but many people eat too much of the wrong things to make any distinction. Eating too much salt can actually harm your body. Sodium is necessary for many bodily functions and eating too much can actually leave you deficient and dehydrated.
However, sea salt is a completely natural product, grown on the seafloor. No mining is required, no chemicals used, no boiling, and no straining! These salts have been found to have very high levels of sodium chloride around 2 times more sodium chloride than you would find in regular table salt! This makes sea salt one of the healthiest alternatives to sodium chloride. Also, these salts are much cheaper than table salt due to the high demand and lower cost per ton.
If sea salt comes from seawater, it is even more environmentally friendly than table salt does. The salt does not use up any of the Earth's energy or create any new pollution. It's better for the environment overall and helps to slow down climate change. It's a much greener alternative than many other options.
Some table salt does contain an iodine reduction agent. Iodine is essential for human beings. When we eat processed foods that have additives and preservatives, iodine deficiency can result. Sea salt contains more iodine because it has been processed and more processing means less iodine is lost during the process of curing it.
The main differences between sea salt and table salt come down to its main ingredients and the processing it goes through. Sea salt is much higher in magnesium and Bicarbonate than table salt is. Processed food often removes some of these important minerals from the food. Sea salt is high in magnesium and Bicarbonate and contains hardly any processing by-products such as lactic acid and mono hydroxyl ether (Methylisothiazolinone).
So the main differences between sea salt and table salt really come down to the processing. Sea salt has more refined, processed foods in it and therefore more iodine. Table salt, on the other hand, has fewer processed foods in it, so it lacks iodine. With more iodine in sea salt and less processing, it retains more of the mineral and thus has a higher mineral content than table salt.
