Sodium: How to tame your salt habit

Use salt substitutes wisely

A salt substitute is made by replacing some or all of the sodium with potassium, magnesium or another mineral. These table salt substitutes help lower the amount of sodium you get, and potassium and magnesium help lower blood pressure. But they need to be used carefully. You can use too much if you are trying to get the same salty taste as you would from table salt.

The potassium in some salt substitutes may be a problem for some people. Too much potassium can be harmful for people with kidney problems. It also can be bad for those who take medicines that cause the body to hold on to potassium. These include medicines used to treat high blood pressure and congestive heart failure.
