Is Gourmet Seasoning Worth Its Salt?

Does it matter which salt you use? Chefs think so, which is why you'll find rock salt, sea salt and fleur de sel in shops. Prices of up to $14 a kilo prove that some consider the flavour special. (Save them for finishing dishes rather than for cooking: once melted they lose their subtle flavour.) But are they healthier? "Sea salt is no better for you than table salt," says Catherine Collins of the British Dietetic Association. "Some producers boast that their salt contains minerals such as calcium and magnesium, but you'd have to eat an enormous amount to get your recommended daily intake this way."
