A: Yes, it depends. All three kosher salt, sea salt, and table salt all contain approximately the same level of salt. That is, one teaspoon of kosher salt produces approximately the same quantity of salt as one teaspoon of sea salt. (The larger crystals of kosher salt may also be tingly sticky).
B: Yes, that's true, but kosher salt contains a lot more sodium than sea salt does. This is due to the concentration of the substance. Sea salt is basically very pure sodium, kosher salt is substantially diluted and the various species of kosher salt have different sodium properties. Therefore when you cook with kosher salt you are actually using much less salt than if you used sea salt or table salt.
C: I suppose you could make your own kosher salt by adding the right amount of baking soda to the salt in a recipe and re-making it. There are a couple of problems with this method, however. For one thing, it creates a salty taste in your food and secondly it strips away some of the natural flavors of kosher salt. Also, the baking soda tends to give saltiness to anything it is added to. This means that sea salt will actually taste better if you haven't added any baking soda. So, since we know kosher salt has its own benefits, why not use sea salt?
D: As for the second question, why not just use regular table salt? Well, there are several major benefits to regular table salt which are hard to ignore. For starters, most of us already know that regular table salt lacks the beneficial minerals that kosher salt contains. In addition, most people recognize the fact that regular table salt is lower in magnesium and other important minerals that help keep our body healthy.
The only problem is that people just don't like the taste. For one thing, regular table salt doesn't have a very salty taste to it. This makes sea salt seem much more appealing. And, since sea salt has so many health benefits, it's really hard to imagine anyone preferring to eat regular table salt all day long.
E: Another issue with regular table salt is that it's actually quite a bit more expensive than kosher salt. Most people can't afford to splurge on the latter and therefore turn to cheaper alternatives. However, cheaper does not always mean healthier. Unrefined sea salt tends to taste far better than regular table salt and it actually contains a lot more nutrients. Therefore, instead of opting for cheap table salts when cooking, why not invest in quality sea salt?
F: We tend to consume way too much salt in our diets. This causes a number of health issues high blood pressure is one, excessive sodium can cause diabetes and/or heart disease, fatigue, and other physical problems. As a result, people who suffer from high blood pressure, kidney disorders, or heart problems should try to reduce their sodium consumption. On the other hand, people who are trying to lose weight should also choose sea salts over table salts when cooking. By using sea salts in place of regular table salt, you can drastically reduce your calorie intake without sacrificing taste!
G: Iodine is a crucial element in keeping our body's cells healthy and functioning properly. In fact, iodine is said to be one of the keys to memory. High levels of iodine are associated with poor thyroid function and other serious health issues. Fortunately, kosher salt contains enough iodine to ensure your diet is rich in this essential mineral. This is especially important during the cold season when iodine is most important. By choosing sea salts as your table salt, you'll be able to ensure you get enough iodine on a regular basis.
