Really? Your an expert and that is what you told someone???? Sea Salt is the best choice overall. Yes, Kosher Salt does have less sodium than sea salt but sea salt has less sodium than table salt and you do want to limit salt all together. Sea Salt retains all its trace minerals because the way it is harvested and this allows it to interact with the bodys cells. Table Salt is processd and stipped of all the trace minerals and does not interact with our cells and can leave some attached to our organs such as our heart and kidneys. Dont take my word for it, look it up there are plenty of scholarly articles that say the same thing
