Sodium (salt) is already added to a lot of processed food so check the labels. The FDA recommends 2300 mg/day max for a low sodium diet, which is a challenging goal considering 1 can of soup could exceed that. Look for ways to control your salt intake such as; low sodium cheese and cold cuts, less sauces, less high carb/high sodium snacks, and obviously taste before you add salt to your food. One teaspoon is equal to about 2300 mg of salt. A lower sodium diet can lower your blood pressure, avoid excess 'water' weight, and is an integral part of a balanced and healthy diet.
