The USDA recommends 2,400 mg or less of sodium (salt) a day. If you need to limit the amount of salt and sodium in your diet, here are some suggestions from the National Heart, Lung and Blood Institute:
Read the food labels to help you pick foods lower in sodium.
Pay attention to the serving size listed on the label. If you eat two cups of a food, but the serving size is one cup, you'll need to double the amount of sodium listed.
Look for foods that use one of these terms on the label: sodium-free, very low sodium, low sodium, reduced sodium, light in sodium or unsalted.
