Tips for People with Chronic Kidney Disease - Sodium (Fact Sheet)

What Is Sodium?

Sodium is a part of salt. Sodium is found in many canned, packaged, and "fast" foods. It is also found in many condiments, seasonings, and meats.

Why Is Sodium Important for People with CKD?

Eating less sodium helps lower blood pressure and may slow down CKD. Talk with your provider about the right blood pressure goal for you.

One of the kidneys' important jobs is to filter sodium out of the body and into the urine. Damaged kidneys cannot filter as well as healthy kidneys can. This can cause sodium to stay in your body and make your blood pressure go up.

How Much Sodium Should I Eat Every Day?

Most people need to eat less sodium than they are eating. Aim for less than 1,500 milligrams of sodium each day. Much of the sodium you eat does not come from a salt shaker. Sodium is added to the prepared foods you buy at the supermarket or at restaurants.

Foods Lower in Sodium:

• Fresh or frozen fruits and vegetables
• Rice, noodles
• Cooked cereal without added salt
• Fresh meat, poultry, seafood
• Low-fat, low-sodium cheese
• Unsalted nuts
• Low- and reduced-sodium frozen dinners, peanut butter, salad dressings
• Air-popped popcorn

Foods Higher in Sodium:

• Bacon, corned beef, ham, hot dogs, luncheon meat, sausage
• Bouillon, canned, and instant soups
• Boxed mixes, like hamburger meals and pancake mix
• Canned beans, chicken, fish and meat
• Canned tomato products, including juice
• Canned and pickled vegetables, vegetable juice
• Cottage cheese
• Frozen meals
• Frozen vegetables with sauce
• Olives, pickles, relish
• Pretzels, chips, crackers, salted nuts
• Salt and salt seasonings, like garlic salt
• Seasoning mix and sauce packets
• Soy sauce
• Salad dressings, bottled sauces, marinades
• Some ready-to-eat cereals, baked goods, breads
• Ready-to-eat boxed meals and side dishes

How Do I Lower the Sodium in My Diet?

• Buy fresh foods more often.
• Cook foods from scratch, instead of eating prepared foods, "fast" foods, frozen dinners, and canned foods that are higher in sodium.
• Use spices, herbs, and sodium-free seasonings in place of salt. Check with your healthcare provider about using salt substitutes.
• Rinse canned vegetables, beans, meats, and fish with water to remove extra sodium.
• Always read the Nutrition Facts label to compare foods. Choose foods with the lowest Percent Daily Value (%DV) for sodium. The %DV lets you see if a food is high or low in sodium. 5% or less is low and 20% or more is high.
• Check the label on fresh meats and poultry. Sodium additives can be used to make meat last longer.
• Look for foods labeled: sodium free, salt free, very low sodium, low sodium, reduced or less sodium, light in sodium, no salt added, unsalted, and lightly salted.
