If you have high blood pressure or heart, liver, or kidney problems eating too much salt can be bad for you. Look for these words on labels: low-sodium, sodium-free, no salt added, sodium-reduced, or unsalted. Check all labels for how much salt or sodium foods there is per serving. Also, avoid foods that list salt near the top of the list of ingredients. A product with less than 100 mg of salt per serving is good.
