Sodium, or salt, is a mineral found in many foods, sometimes in very high amounts. The typical American eats much more salt than the body needs. If you're eating more than a pinch of salt a day -- about a teaspoon -- you are eating more than recommended. Too much salt in your diet affects your body's fluid balance and can lead to serious health problems, including high blood pressure and kidney disease. A healthy diet is one that is low in sodium. For most adults that means no more than 1,500 milligrams per day. Follow the links below to find WebMD's comprehensive coverage about sodium, including tips for following a low-sodium diet, and much more.
