Dietary Recommendations for Reduced Sodium


Under certain conditions, excess sodium can cause the body to retain too much fluid. This can be harmful for people with conditions such as high blood pressure, heart disease or cirrhosis. Restricting the total amount of sodium in the diet to 4 grams/day may be adequate. However, some patients may need to restrict their intake to 2 grams/day.

  • Table Salt is used in the kitchen during food preparation, and added at the table. It is also added to many commercially canned and frozen foods. It must be restricted in these diets because table salt is about one-half sodium.
  • Sodium occurs naturally in many foods, but some foods contain more sodium that others. As a helpful guide: for the 4 grams/day diet, purchase products with no more than 300mg of sodium per serving. And for the 2 grams/day diet, purchase products with no more than 200mg of sodium per serving.
  • Sodium compounds, in addition to table salt, are often added to commercially processed foods. Some of those more commonly used are baking soda, brine, monosodium glutamate (MSG), baking powder, disodium phosphate or sodium benzoate. Please read food labels before purchasing or using.
  • Common medications such as antacids, laxatives and cough remedies often contain sodium compounds. Check with a physician or pharmacist if there is any question.
  • Avoid fast food restaurants because they tend to serve food that is very high in sodium. When dining in sit-down restaurants, ask that no salt be used in the preparation of your meal.
  • Never use a salt substitute unless your physician has approved it. These may replace the sodium with another mineral that could also be harmful to certain patients. Herbs and spices may be used in place of salt to add flavor and variety to meals.
  • Water softeners exchange the calcium in hard water with sodium from salt brine. Avoid drinking home or commercially softened water. Do not use softened water to prepare foods or beverages. When purchasing bottled water, check the label to be sure it contains so sodium.
