Salt and Kidney Disease
Americans love salt. Fast food and prepared foods are loaded with it. While these foods are cheap and tasty, when you’ve got chronic kidney disease, salt is not your friend. Why? Because salt is mostly sodium, and your kidneys may have trouble keeping your sodium and water in balance. That can mean feeling thirsty, fluid weight gain, and high blood pressure (HBP).

America: Land of the Super Saltshakers
The average American consumes 3,400 mg of sodium a day. The recommended daily allowance for people on dialysis or living with CKD varies from 750 mg - 2000 mg per day.
TIPS TO REDUCE YOUR SALT INTAKE
Limiting the amount of salt in your diet is important when you’re on dialysis. Learn simple ways to shake off the salt!
Tips to toss that saltHere’s how to cut salt from your diet:
Cook with herbs and spices for flavor instead of salt. Believe it or not, the less salt you use, the less you will crave. Some people don’t even miss it after a while—or they notice many prepared or restaurant dishes are too salty to enjoy.
Look at food labels for sodium. Some foods may not taste salty, but still contain a lot of salt.
Cut back on convenience foods and prepackaged or frozen meals. They’re salt central. Again, read the labels.
Try to avoid fast food, but if you decide to indulge on occasion, look at the nutritional information posted inside the restaurant or on their website.
WAY TO THRIVE
How much is too much salt? For packaged foods, simply look at the label.
Look for foods with less than 10% Daily Value (DV) for sodium to select lower sodium items.
Chili powder—tastes great in chili or taco meat flavoring. Also try it in rubs. View a recipe using this spice.
Smoked paprika—adds a smoky flavor to marinades, gives brown color to breadcrumb casserole toppings and is great for barbecue rubs, or seasoning blends for sautéing or searing proteins. View a recipe using this spice.
Lemon zest—adds a lively taste to breadcrumbs, breaded chicken tenders, fish sticks and kidney-friendly vegetables (eggplant, string beans). Lemon zest is also great in dressings, marinades and when added to dry spices for rubs. View a recipe using this spice.
Dried oregano—enhances flavor of scampi sauces and combines well with lemon zest. Gives steamed vegetables and tossed salads a fresh, earthy taste and aroma. Add it to fajita seasonings with chili powder, cumin, cayenne and lemon zest. View a recipe using this spice.
Italian seasoning*—a blend of thyme, oregano and basil is great for finishing off sauces such as a stroganoff or gravies. Works well on baked, grilled or sautéed proteins with lemon zest and a little oil. Add it to lemon zest, lemon juice and olive oil to make delicious dressings. View a recipe using this spice.
*Check to be sure you are using a salt-free product.
Salt alternatives (not substitutes!)
There are many salt alternatives, including flavorful spices and seasonings. However, “classic” salt substitutes simply switch out sodium for another mineral, potassium. Unfortunately, that’s also a problem when you have chronic kidney disease. It’s important to steer clear of salt substitutes made with potassium if your dietitian or doctor has recommended a low potassium diet.
Salty foods to watch out for
Learn the reduced-salt lingo
- Sodium-free—only the tiniest amount of sodium per serving
- Very-low sodium—35 mg or less per serving
- Low sodium—140 mg or less per serving
- Reduced sodium—foods where the level of sodium is reduced by 25%
- Light or “lite” in sodium—foods where the sodium is reduced by at least 50%
Remember, “reduced” sodium, as well as “light” or “lite in sodium" are relative to their full-sodium counterparts. For example, “lite” soy sauce is better than “regular” soy sauce, but “lite” soy sauce is still high in sodium. Always check the label to see how many milligrams of sodium it contains.
It's best to ask your dietitian since everyone's needs are different.
