Sea salt no better than regular salt - both are sodium chloride

Nutrition Health Review, Fall, 1990

Sea Salt Not Better Than Regular Salt

Sea salt is not more healthful than regular salt. Salt is sodium chloride, no matter from what its derivation.

Sea salt is essentially sodium chloride, and refined salt, obtained from the sea, has little nutritional advantage.

Sea salt does contain some minerals not present in ordinary table salt such as magnesium, sulfur, calcium, and potassium, but the amount of these trace minerals is practically undetectable.

Many products that purport to be healthful emphasize sea salt as part of the contents. Consumers who are eager to avoid the problems of salt overload should be aware that sea salt makes the same contribution to kidney problems as table salt.
