There are three main salt categories: table salt, regular sea salt / kosher salt and then finishing salt. Gram per gram table salt, sea salt & finishing salts have the same amount of sodium. However, per teaspoon sea salt and finishing salts typically contain less sodium. The main differences between any salt is the processing, texture, flavor and iodine content.
SEE SALT fleur de sel, a type of sea salt, is great used as a finishing salt to boost the flavor of a meal right before serving. Waiting to season your meal with sea salt right before serving (versus during the cooking process) is an excellent way to monitor sodium intake & use less overall. Larger crystals of sea salts & finishing salts may result in an individual consuming less overall as well.
