Kidney Disease: Eating Less Sodium

Choose a preferred language

Sodium is a mineral. Your body needs it in small amounts. But most people eat far more salt than they need. There's often a lot of salt in packaged foods and in restaurant foods. If you cook with fresh foods at home, it's easier to control your salt.

Eating too much sodium can make your body retain fluid. It can put stress on your kidneys. People with chronic kidney disease are often told to eat less sodium. This sheet can show you how.

People with chronic kidney disease should have less than 1,500 milligrams (mg) of sodium daily. Table salt is sodium chloride. One level teaspoon of table salt has 2,300 mg of sodium.

When you shop for food

When you’re food shopping:

  • Buy fresh foods when you can. They have no added salt. Cook them at home instead of buying prepared foods.

  • Choose canned or frozen vegetables with no added salt.

  • Choose fresh or frozen poultry, seafood, and lean meats.

When you're buying packaged foods:

  • Read the Nutrition Facts label. It will tell you how much sodium a food or drink has. Check the sodium amount per serving. Then check how many servings there are in the package.

  • Check the sodium content of drinks as well as food.

  • Pick foods with 140 mg or less of sodium per serving.

  • Don't choose foods with more than 400 mg of sodium per serving.


When you cook at home

You can season foods without salt and still have tasty meals. Try these herbs and spices in these foods:

  • Basil: tomatoes, squash, eggplant, soups, fish.

  • Curry: soups, rice, lentils, chicken.

  • Dill: beets, cucumbers, green beans.

  • Garlic: sauces, beans, vegetables, meats, fish.

  • Ginger: carrots, chicken, cooked fruit, white sauces.

  • Lemon: asparagus, artichokes, broccoli, spinach, fish.

  • Mint: cold soups, salads, fruit dishes.

  • Oregano: eggplant, chicken, salads, sauces.

  • Thyme: chicken, fish, lean meats, soups, stews.

If you use salt at home, keep these things in mind:

  • Food with salt added during cooking tastes less salty than when salt is added at the table. So use less salt when you cook. Sprinkle salt at the table if needed.

  • Don't use seasoned salt or salt substitutes. They may contain potassium. This is a mineral people with kidney disease often need to limit.

But you may need to be more aware of foods that make your stool more watery than normal and foods that cause gas or odor. You also need plenty of fluids and vitamins.
