Sodium is an important factor in the diet and in your health. Although we require some sodium for the normal functioning of our bodies, the average American diet has much larger amounts of sodium than is necessary. In many people, this high sodium intake contributes to kidney failure, as well as heart attacks, heart failure and stroke. Most patients with chronic kidney disease, high blood pressure, heart failure, stroke or swelling need to limit their sodium intake.

A normal American diet contains about 5 grams (5,000 milligrams) of sodium per day!   This is much too high even if your blood pressure is normal.

Most people with high blood pressure are aware that sodium may be raising their blood pressure.  There is an incorrect belief that if one is not using a salt shaker or adding salt while cooking, that this can be considered a low sodium diet.

Did you know that less than 10% of the average person’s total sodium intake comes from the salt shaker, while over 90% is hidden in foods, most of which are prepared and/or packaged?

It is important to reduce your sodium consumption to 2,000 milligrams a day or less.  Sodium restriction at this level is also important in many patients with chronic kidney disease even if their blood pressure is well controlled, to prevent the development of high blood pressure, fluid overload and swelling, and worsening of your kidney function.

Although a low sodium diet may seem bland and tasteless initially, it does not take long for most people to become accustomed to low sodium foods. If the low sodium diet is followed carefully, it becomes relatively easy to recognize or taste foods containing high amounts of sodium and to avoid them.

In general, foods that are high in sodium and should be avoided are processed and prepared foods such as soups, sauces, pickles, fast food, pizza, prepared meats including bacon, ham, hot dogs, sausages, deli meats, and other processed foods such as cheese, crackers, pretzels, chips, bread, and most snack foods. The list of high sodium foods is far too long to list, so the only way to be sure to avoid sodium is to read all labels on any packaged foods and to ask about sodium content in menu items whenever you eat out. A very short sample of foods and their sodium content is provided below, to emphasize the large amounts of sodium found in commonly consumed foods.

The National Kidney Foundation also has a great deal of information and tips to help you lower the sodium in your diet.  Click here to access this site.
