So, your doctor told you to start following a low sodium diet. You are probably wondering how you can make your food taste good without the salt! The good news is that you absolutely can (and should!) eat flavorful, delicious meals on a low sodium diet. You just need to learn some new kitchen tricks!
Here is a complete list of healthy salt substitutes for kidney patients. And, which salt substitutes to avoid.
Low Sodium Diet for Kidney Disease
A low sodium diet is a pillar of healthy eating for nearly every health condition that affects the kidneys. People with Chronic Kidney Disease, Polycystic Kidney Disease, FSGS, nephrotic syndrome and kidney stones should all avoid too much salt.
A high salt diet can cause high blood pressure, which is harmful to kidneys. In fact, high blood pressure is the second leading cause of Chronic Kidney Disease in the United States. In addition, a high salt diet can make uncomfortable swelling, or water retention, worse for people with kidney disease.
For most people, a healthy daily sodium goal is 1,500-2,300mg per day. Only 1 teaspoon of salt has around 2,300 mg of sodium. This is less than half of what most people in the United States eat every day!
It is very important to realize that most of the salt we eat is already in our food. The best place to start removing salt from your diet is to eat foods low in sodium in the first place! Then, make those foods tasty with a healthy salt substitute for kidney patients!
Salt Substitute for Kidney Patients to Avoid
Artificial Salt Substitutes
Products marketed as “salt substitutes” or “low sodium salt” can actually be dangerous for kidney patients. Most of these products replace sodium chloride (salt) with potassium chloride. For many kidney patients, these salt substitutes provide far too much potassium for kidneys to handle. Although not all kidney patients need to limit how much potassium they eat, I do recommend avoiding artificial potassium for anyone with kidney disease.
Salt substitutes can have a surprising amount of potassium in them. “Nu Salt” contains 3,180mg of potassium per teaspoon, which is more than many patients with kidney disease should eat in an entire day!
Examples of salt substitutes made with potassium. Kidney patients should avoid all of these salt substitutes.
- Nu Salt (3,180mg potassium per teaspoon)
- No Salt (2,560mg potassium per teaspoon)
- Morton’s Lite Salt (1,400mg potassium per teaspoon)
- Morton’s Salt Substitute (2,440mg potassium per teaspoon)
- Diamond Crystal Salt Sense (unable to find potassium amount)
In addition, many of these salt substitutes have a somewhat bitter or metallic taste. Personally, I don’t love the flavor!
Read Food Labels for Potassium
How do you know if your salt substitute has potassium in it? Check out the “Ingredients” section of the Nutrition Facts label. Look for potassium chloride, potassium iodide or any other ingredient that contains potassium.
Additionally, many low sodium food products are made with salt substitutes. For example, Healthy Choice canned soups are made with potassium chloride. A single cup of Healthy Choice Chicken & Dumplings soup contains 380mg of potassium. Make sure to check all food labels for potassium additives.
Spice Blends with Salt
Most spice blends you buy at the grocery store contain salt. For example, taco seasoning has a surprising amount of sodium in it. Many other spice mixes such as grilling seasoning, BBQ rubs, Italian seasoning, mesquite seasoning and stir fry seasoning have salt in them.
Not only do spice blends with salt add unnecessary salt to your food, they are expensive! Salt is very inexpensive, compared to dried herbs and spices. Salt is used as a filler in many spice blends. Save money and make your own salt free version at home!
Not all spice blends have salt in them. It is very product-specific. Always make sure to read Nutrition Facts labels to check for sodium content. You can also check out the ingredients to make sure salt is not added.
It is better to mix your own seasoning blend at home. Try this salt-free taco seasoning. Or, you can find many salt-free seasoning blends in the grocery store as well (keep reading for great salt-free options!).
There are many salts available that may appear to be healthier than traditional iodized salt. However, all of these specialty salts are still salt. They are not any healthier than regular salt.
Specialty salts for kidney patients to avoid. These all have the same amount of salt as plain salt!
- Himalayan pink salt
- Kosher salt
- Sea salt
- Rock salt
If you cook your food from scratch and choose primarily low sodium ingredients, there is room in a low sodium diet to add a small amount of salt to your food. If you prefer the taste of any of these fancy salts, then go ahead and use it! But, know that it is not any healthier than regular salt.
Lemon Pepper Seasoning
Traditional Lawry’s Lemon Pepper seasoning contains a surprising amount of sodium. One teaspoon has 320mg of sodium.
Try Mrs. Dash’s Salt Free Lemon Pepper*. Or, try making your own lemon pepper seasoning instead. Black pepper and fresh lemon juice is another great option.
Lawry’s Seasoned Salt has a large amount of salt (1,520mg of sodium per teaspoon) in it. It also has artificial phosphorus (via tricalcium phosphate) in it. Artificial phosphorus is harmful to people with kidney disease.
Top Salt Substitute for Kidney Patients
Herbs and Spices
Simple, but true. Herbs and spices are the single best salt substitute for kidney patients. The best way to add flavor to your food without adding salt is to use them. A lot of them.
Any herb or spice is a wonderful option for people with kidney disease or kidney stones. Try experimenting with new flavors. You might find some new tastes you love. Here are my personal favorite herbs and spices to use.
- Garlic & Onion Powder
- Garlic and onion powder are great universal flavors that go on just about anything. Sprinkle these on chicken, steak, pork, fish or vegetables before (or after!) cooking.
- Dill Weed
- Probably one of my favorite flavors, dill also goes on just about anything. My favorite foods to season with dill are any kind of fish (especially tuna salad). Dill is also wonderful on chicken or pork. Try these roasted dill carrots!
- Cumin has a wonderful smoky, almost spicy, flavor. I love to add cumin to any Mexican inspired dish such as taco filling or breakfast tacos with onions and peppers. Cumin also goes wonderfully with beans and greens (try collards or mustard greens or kale). I also love it in these vegetarian stuffed peppers.
- Cumin is frequently used in Indian dishes as well, along with many other tasty spices. Try this Indian Chicken Curry!
- Chili Powder
- Chili powder can be used for much more than just chili! Try making some butternut squash and poblano pepper tacos with a mix of chili powder and cumin to add flavor.
- Rosemary & Thyme
- Perfect for nearly all poultry dishes. Also delicious on fish and white beans.
- Cinnamon & Nutmeg
- Smoked Paprika
- If you have never tried smoked paprika, pick it up next time you are at the grocery store. A little bit of this potent condiment goes a long way! Add it to soups, stews, greens or beans in place of smoked meat or sausage to mimic that smoky flavor!
- Crushed Red Pepper Flakes & Cayenne Pepper
- If you love spicy food, these two are your new best friends! Be careful, the longer you cook these spices, the hotter they get! Low sodium hot sauces are also an option for spicy food lovers.
Fresh vs. Dried Herbs
Both dried and fresh herbs and spices are wonderful additions to a low sodium, kidney healthy diet. Although fresh herbs tend to taste better, I generally use more dried herbs because they are cost-effective compared to fresh. However, I do love having fresh cilantro to make my own pico de gallo or to throw on top of Thai or Indian curry dishes. Also, what is better than the smell of fresh basil?
If you are able, growing your own herbs is a wonderful, cheap way to have fresh herbs at your disposal. I also love being able to harvest just the amount I need for a recipe.
It ultimately is a personal decision to use dried or fresh herbs. There is not a real nutrition benefit either way.
You can substitute dried for fresh herbs in recipes. A good rule of thumb is to use 1 teaspoon of dried herb, for every 1 tablespoon of fresh in a recipe. For example, if a recipe calls for 2 tablespoons of chopped fresh oregano, use only 2 teaspoons of dried oregano. Dried herbs are more potent than fresh!
Salt-Free Seasoning Mixes
There are many salt-free seasoning mixes available. The key is to never assume a spice does not have salt – always read the nutrition facts label! Here are some of the more more common salt-free seasoning blends available. Plus, some of my favorite brands!
Mrs. Dash has become practically synonymous with a low salt diet. For good reason! Every Mrs. Dash seasoning blend is salt free and a great salt substitute for kidney patients!
If you haven’t checked out Mrs. Dash in awhile, make sure to go down the spice isle next time you are grocery shopping. There are a ton of different flavors available, other than the original Table Blend*. Some popular flavors are:
- Garlic & Herb*
- Onion & Herb*
- Lemon Pepper*
- Taco Seasoning*
- Fiesta Lime* (great for making elote!)
- Steak Seasoning*
- Spicy Jalapeno*
- Southwest Chipotle*
McCormick Salt Free Seasoning Mixes
Not all of McCormick’s seasoning mixes are salt free, but they do have many wonderful salt free choices. Notably, McCormick makes a salt-free onion & herb*, garlic & herb* and roasted garlic and bell pepper* seasoning mix. Make sure to pick the salt-free version of these mixes.
Recently, McCormick has released their “Perfect Pinch” seasoning mixes in many enticing flavors such as Caribbean Jerk, cajun and roasted garlic and bell pepper. Unfortunately, most of these mixes have salt in them. The Italian* flavor of the Perfect Pinch line is the only exception.
If you haven’t heard of Penzey’s Spices, definitely give them a look. Penzey’s is known for their tasty seasoning blends for every occasion and unique combinations.
Not all of Penzey’s spice mixes are salt-free, but many are! Some great no salt options are:
- Chili Con Carne Seasoning
- Berbere (super spicy!)
- Sunny Spain
- Tuscan Sunset
- Mural of Flavor
- Jerk Chicken & Fish
- Pasta Sprinkle
Vinegar is perhaps the most underestimated salt substitute for kidney patients. Using a splash of vinegar near the end of cooking adds a ton of bright flavor to nearly any dish.
Here are my personal favorite flavors of vinegar:
- Balsamic Vinegar
- A classic! Try making your own salad dressing with balsamic vinegar. It is also delicious on poultry and fish. Balsamic vinegar is slightly sweet, so pairs wonderfully with bitter veggies like spinach, collards or kale. It can also help enhance the sweet flavor of slightly sweet veggies like sweet potatoes, butternut squash or pumpkin.
- Grilled or caramelized onions with a splash of balsamic vinegar is a wonderful topping for sandwiches, pasta or salads. Or, just served as a side dish!
- Also, if you haven’t tried balsamic drizzle before, you are missing out! Balsamic drizzle is basically just balsamic vinegar boiled down until it is thick, sweet and even more full of flavor! You can make your own balsamic drizzle by bringing 1-2 cups of balsamic vinegar to simmer and cooking until thickened, 30-45 minutes. Or, you can buy it at most grocery stores. Trader Joe’s Balsamic Drizzle* is my favorite.
- For a fancy balsamic vinegar, try O White Balsamic Vinegar*. This vinegar is even sweeter than most balsamic vinegar, and a less harsh, acidic flavor.
- Red Wine Vinegar
- Red wine vinegar can add a ton of flavor to your food. Add some at the end of tomato based sauces or soups to elevate the flavor.
- Sherry Vinegar
- If you’ve never tried sherry vinegar, you haven’t lived. Sherry vinegar has a slightly sweet, mellow vinegar flavor and is delicious to use on nearly anything. Add it to homemade sauces, soups or even egg dishes to truly elevate the flavor. O Aged Sherry Vinegar* is my favorite.
No Sodium Salad Dressing
Flavored vinegar makes a wonderful low sodium salad dressing. Simply whisk 1 tablespoon of your favorite flavored vinegar with 3 tablespoons oil (choose olive oil for a heart healthy fat!) and you are good to go!
If you would like to stop your vinaigrette from separating, add 1-2 teaspoons of Dijon mustard or mayonnaise to help it stay emulsified.
Fresh Lemon & Lime Juice
This is one of my favorite tricks for low sodium cooking. Citrus juices are wonderful salt substitutes for kidney patients. Try sprinkling fresh lemon juice on chicken noodle soup right before you eat it. Or, add it to baked chicken, fish, nearly any vegetable or pasta dish.
Add fresh lime juice on Indian or Thai curry for an amazing bright flavor. Lime juice also goes wonderfully with most Mexican-inspired dishes.
Fresh citrus will give you much more flavor. However, for convenience sake, bottled lemon or lime juice from concentrate also works!
Fresh Onion & Garlic
It may be odd to think about using onion and garlic as a salt substitute. However, using very flavorful ingredients like these help your food taste delicious without added salt.
A staple to nearly all types of cooking, you can’t go wrong with fresh onion and garlic. Use these ingredients as a base for homemade soups, stews and sauces. I always recommend sauteing or roasting onion and garlic, as this will bring out even more flavor! For example, starting a soup with sauteing onion in some oil will add much more tasty flavor compared to adding them directly in the broth.
This trick works for dried spices as well! Toasting your spices in a small bit of oil (or even just in a dry pot) for a few minutes will enhance their flavor.

Is Spike a good seasoning to use in a ckd diet?
Spike seasoning has 160mg sodium per 1/4 teaspoons – this is a low sodium seasoning option, but not as low as actual herbs and spices (which have 0mg sodium!). If you love this seasoning, I’m sure it could be incorporated into a healthy kidney diet by just taking that sodium into account for your daily total. Ask your dietitian what is best for you!
What is your opinion of green salt?
It does have less sodium than regular salt! However, there is still a fair amount of sodium in there. If you like it, it can certainly be used in moderation!
I’d also add Trader Joe’s “21 Seasoning Salute” to your list of good spices. No salt, plus it contains lemon juice powder, oil of lemon, and citric acid! I’m addicted to it and put it on just about everything, but it’s especially tasty as a topping to Ezekiel Bread toast with sunflower seed butter, tahini (yeah, I know that’s high in oxalates :-(), or avocado. See https://www.amazon.com/Trader-Joes-Seasoning-Salute-Blend/dp/B00ICTMA0E, but it’s only about $2 at Trader Joe’s itself.
PS – I could have sworn there was a way to search your site, but I can’t find it now.
PPS – I could have sworn I’ve posted a few comments that seem not to have made it into the site. I guess you can’t respond to every post, and maybe you’ve had other things to do recently – twins perhaps! – but is there any way to see all the comments I’ve posted using my email address?
Hi John! I love that seasoning from TJs! You can search my site on a laptop – but not the mobile version. You should always be able to search in the top right. I do have to manually approve all comments (this helps keep the spam down!), so yes, twins are the reason for the delay in you seeing your comments 🙂
I’m still not seeing any way to search on the menu bar, which for me, contains these items from left to right: About, Blog, Kidney Healthy Recipes, Shop, Resources, Contact. I’m using a browser on a PC laptop.
Hi John! Thank you for bringing this to my attention. The search bar actually disappeared and I just got it back. It should be working now!
I’m hoping that you will have some advice. My 88 yo father has stage IV kidney failure and also end stage CHF. He lives in an ALF and is struggling with the food having no seasoning/taste. He cannot use the salt substitutes/lite salts because they contain so much potassium which is horrible for his kidney failure. And his cardiologist is telling him to avoid salt due to his CHF. We have tried Mrs. Dash, and he absolutely hates it. Being in an ALF, fresh herbs aren’t really an option. Do you have any ideas? Thanks
I’d try supplying him with a variety of dried spices and herbs to put on his food! Things like garlic powder and onion powder go on pretty much anything!
I recommend playing around with citric acid, which you can find in international markets and is very cheap (or should be). Mixing it with your favorite salt (called ‘sour salt’ commercially), you can reduce your sodium intake without losing what salt brings to food. Citric acid is used in a lot of Middle Eastern and Asian cuisines. It functions in the same way as vinegar or lemon/lime juices, in adding acid to your food to enhance flavor. I use it in place of salt in my chicken salad and my wife, who loves salty food, can’t tell the difference (the mayo and poached chicken both have sodium).
I have high oxalate in urine test, do some (dried) herbs and spices have to be avoided for oxalates? I ask because I am used to cooking with a lot of herbs and spices in rather large quantities so it could potentially influence my oxalate?
The amount of oxalate you get from spices and herbs used in cooking is truly minimal and not a concern for most people. Ask your dietitian what is best for you!
Give us more information on these seasonings and dialysis patients.
Hi Ronald! All of these salt-free seasonings are wonderful options for dialysis patients!
I love the Tajin seasoning…unfortunately it has a lot of Salt (even the low salt version). Do you have a recipe with no salt version?
I love that seasoning as well! The low sodium version only has 120mg per 1/4 teaspoon – which isn’t crazy. But, I agree we can do better! The ingredients in Tajin seasoning are chili peppers, lime and salt. I bet you could get similar flavor with cayenne, chili powder and lime zest!
The low sodium Tajin has ‘potassium salt’ … ? The original blend does not have it. 190 vs 120 is not a huge difference, is it? Since this seasoning is sprinkled on food, not used by the tsp I wouldn’t think.
Hi Sherry! Certainly a little of any kind of salt can be used – it just needs to fit in your daily sodium limits. A sprinkle of the original is likely fine!
What about using extra virgin coconut oil? Is it a good choice for cooking or instead of butter?
Hello! I do not recommend coconut oil over butter. Coconut oil actually has more saturated fat in it than butter! I would use it sparingly, just like unsalted butter. Hope this helps!
