Sea salt and pink Himalayan salt are the natural, healthy choice, lower in sodium and packed with minerals, while plain table salt is the processed bad guy. The fancy crystals cost five times as much, so they must be five times better for you.
Gram for gram, sea salt, Himalayan salt, and ordinary table salt contain about the same amount of sodium, because they are all basically sodium chloride. The fancy ones do carry tiny traces of other minerals, but the amounts are so small they make no meaningful nutritional difference; you would have to eat a dangerous mountain of salt to get a useful dose of anything from them. If anything, table salt has one genuine health edge: it is usually fortified with iodine, which most fancy salts are not, and iodine deficiency is a real problem the iodisation of table salt was introduced to fix. The differences people pay for are crystal size, texture, and colour, which can matter for cooking and looks, not health. So the pink salt grinder is buying you aesthetics and a slightly fancier crunch. Your blood pressure cannot tell the difference, and your wallet definitely can.
