Despite the fact that sea salt is often promoted as being a healthier type of salt, it has the same basic nutritional value as table salt. In fact, by weight sea salt and table salt contain comparable amounts of sodium. The main differences between sea salt and table salt are in their taste, texture and processing. Whichever type of salt you enjoy, do so in moderation. The Dietary Guidelines for Americans recommend limiting sodium to less than 2,300 milligrams a day.
