Table salt is an important part of a healthy diet. It varies in various forms depending on where it comes from and how it's prepared. Although table salt can be purchased at most any grocery store, it is better to buy organic unsalted table salt and avoid using packaged table salt in your cooking.
Sea salt is seawater that has gone through evaporation. It's most often used for seasoning cooking, baking, cosmetics, and maintaining food in its fresh state. It's also known as mined salt, sea salt, or marine salt. Like other refined sugars, the production of sea salt dates back to prehistoric times when men first discovered how to use rock salts to taste better. Today, sea salt contains much less sodium than table salt does and is much healthier for you.
Oceanic table salt doesn't contain any form of potassium. This is because potassium, like sodium, is required by the body for various functions. Potassium helps make nerve cells work properly and helps maintain muscle strength. It's also good for regulating heart rate and for regulating blood pressure.
However, oceanic table salt does contain trace minerals that are good for our health. For example, magnesium and potassium make up a reduced version of our own mineral sodium. In addition to these trace minerals, trace elements such as uranium, chromium, iron, and selenium are also found in trace amounts in many types of table salt. In recent years, however, many people have become concerned about the amount of iodine found in processed table salt as this element is considered a threat to thyroid health.
Oceanic table salt does contain a certain amount of iodine, but it's not enough to be of any health threat. Iodine is found in seawater and the levels naturally in seawater are extremely low. Anytime you see table salt labeled as "kosher" or "halal", it's likely that it contains some level of iodine. But this iodine doesn't have any dangerous effects on human health. So, when shopping for table salt, it's a good idea to read the labels carefully and look for the "kosher" or "halal" symbol underneath the name of the salt in the list of ingredients.
The other type of table salt that has no harmful effects is the "natural" variety that we see on grocery store shelves. The most commonly available varieties of kosher salt do not contain any additives or preservatives, although they may still contain some color. For instance, rock salt is naturally gray. But, table salt with natural color will taste better and add to the flavor of food. Most natural table salt has a slightly salty taste. It usually has more minerals and trace elements than an artificially colored variety.
The trace amounts of potassium and magnesium found in seawater are also found naturally in table salt. Rock salt does not contain any of these trace amounts, because its brine water content is too low. Saltworks by bringing out the flavor and acidity of the foods we eat without adding any extra sodium.
