WebMD – Signs Your Eating Too Much Salt

Salt is a seasoning that can flavor food and act as a preservative. It’s about 60% chloride and about 40% sodium. Nearly all unprocessed foods — think veggies, fruits, nuts, meats, whole grains, and dairy foods — are low in sodium. The salt that we do eat helps relax and contract muscles, lends a hand with nerve impulses, and balances the minerals and water we take in.
