Q: What is the relationship between sodium and heart disease? Is some salt necessary for good health?

A:  If you have been diagnosed with congestive heart failure, it’s essential to restrict your salt intake. That’s because salt promotes fluid retention, and excess fluid in the body contributes to the complications that can lead to congestive heart failure.

Cutting your salt intake also may play a role in managing high blood pressure. Several studies have shown just removing the salt shaker from the dinner table can reduce salt intake enough to lower blood pressure.

Bear in mind, salt is only part of the blood pressure management story, one that includes taking prescribed medication, a healthy diet, exercising and not smoking.

When cutting back on salt, remember sodium is hidden in many foods, including processed meats, snacks, canned foods and soups. Beware of foods with salty ingredients or preservatives such as monosodium glutamate, baking soda, baking powder, sodium citrate and sodium benzoate.

Of course, a small amount of salt—about one-third of a teaspoon per day—is needed to keep your body healthy. So, skip the excess salt. Bring out the flavor of food with herbs, spices and lemon juice.

If you’re still concerned about your salt intake, talk with your doctor. Together, you can work out a program that’s right for you.
