You probably think of corn chips and potato chips as salty foods, but the surprising fact is that Frito-Lay snacks contain less salt than you might think. For instance, a 1 oz serving of Lay's® potato chips contains less than 1/12th of a teaspoon of salt. That's less salt than in a serving of wheat crackers.
It might sound strange, but it's true, potato and corn chips taste saltier than some other foods because the salt in chips is sprinkled on the surface, rather than baked in, so it is one of the first tastes your tongue detects.
It's also important to know exactly what salt is, and the role it plays in your body. Sodium chloride, what we call salt, helps maintain our body's fluid volume and electrolyte balance. The 2010 Dietary Guidelines recommend that Americans consume no more than 2300 mg of sodium per day (about 1 tsp of salt).
