For approximately 1 in 3 American adults managing diabetes, chronic kidney disease (CKD) also presents a significant health challenge. Navigating dietary choices can feel overwhelming, as the ideal diet for diabetes shares similarities with a CKD diet, yet crucial differences exist. This article aims to provide a comprehensive guide to a low-salt diabetic diet plan, incorporating the latest recommendations and practical tips for managing both conditions effectively.
Understanding the Basics
A healthy diabetes diet generally resembles a healthy diet for anyone, emphasizing fruits, vegetables, healthy fats, and lean protein while limiting salt, sugar, and refined carbohydrates. With a CKD diet, you'll avoid or limit certain foods to protect your kidneys, while including other foods to give you energy and keep you nourished.
Key Differences and Considerations
While both diets prioritize whole, unprocessed foods, the CKD diet often requires stricter limitations on sodium, potassium, phosphorus, and protein, depending on the stage of kidney disease.
The Importance of a Low-Sodium Diet for Diabetics
Individuals with diabetes are already at a higher risk for high blood pressure, and excessive sodium intake can exacerbate this risk. Therefore, a low-sodium diet is crucial for managing blood pressure, protecting heart health, and preserving kidney function.
Benefits of a Low-Sodium Diet
- Improved blood pressure control: High sodium intake can elevate blood pressure, which you are at higher risk for with diabetes.
- Reduced risk of cardiovascular disease: Having diabetes increases your risk of heart disease. Lowering sodium intake can help protect your heart health.
- Better kidney function: Diabetes can affect kidney function, and a high-sodium diet can worsen this over time. Lower sodium helps reduce stress on the kidneys.
How Sodium Affects Diabetes and Blood Pressure
- Fluid retention: Sodium attracts and retains water. When you eat excess sodium, your body holds on to more fluid, which can increase blood volume and potentially elevate blood pressure.
- Worsen insulin resistance: High sodium may worsen insulin resistance, leading to higher blood sugar levels and further diabetes complications.
- Cardiovascular strain: The combination of high blood pressure and diabetes can significantly increase the risk of heart disease such as stroke, heart attack, and heart failure.
Practical Tips for Reducing Sodium Intake
Reducing sodium doesn't mean sacrificing flavor. Here are some practical tips:

- Read Food Labels For Sodium Content: Get in the habit of checking food labels. Pay close attention to the nutrition facts label on food packaging and check for the sodium content per serving. Aim for products with lower values (sodium below 5% daily value is considered low-anything above 15% daily value is high).
- Avoid Processed And Packaged Foods: Processed foods, such as frozen meals, packaged snacks, and canned soups, often contain high amounts of sodium and sugar. Instead, choose fresh, whole foods whenever possible.
- Incorporate More Fruits And Vegetables Into Meals: Fruits and vegetables are naturally low in sodium and sugar and are packed with essential nutrients. Aim to make them a main part of your meals and snacks.
- Use Herbs And Spices To Add Flavor Without Salt: Have fun experimenting with various herbs, spices, and citrus juices to enhance the flavor of your dishes.

Here is a recipe for a sodium-free spice blend (makes about ⅓ cup):
- 5 teaspoons onion powder
- 2½ teaspoons garlic powder
- 2½ teaspoons paprika
- 2½ teaspoon dry mustard
- 1½ teaspoon crushed thyme leaves
- ½ teaspoon white pepper
- ¼ teaspoon celery seed
Salt-Free Flavor Pairings
Here’s are examples of salt-free flavors that pair well with chicken, beef, pork, eggs, fish, and vegetables:
- Chicken: Basil, cloves, cranberries, mace, mushrooms (fresh), nutmeg, oregano, paprika, parsley, pineapple, saffron, sage, savory, tarragon, thyme, tomato, turmeric.
- Beef: Basil, bay leaf, caraway, curry, dill, dry mustard, garlic, grape jelly, green pepper, mace, marjoram, mushrooms (fresh), nutmeg, onion or onion powder, parsley, pepper, rosemary, sage.

- Fish: Basil, bay leaf, chervil, curry, dill, dry mustard, green pepper, lemon juice, marjoram, mushrooms (fresh), paprika, pepper, tarragon, tomato, turmeric.
- Vegetables: Basil, dill, garlic or garlic powder, ginger, lemon juice, mace, marjoram, nutmeg, onion or onion powder, tarragon, tomato, sugar or sugar substitute, salt-free salad dressing, vinegar.
- Cook More Meals At Home: When cooking at home, you have greater control over your meals' ingredients and sodium content.
- Be Mindful When Dining Out: Restaurant meals can be surprisingly high in sodium. Ask for dishes to be prepared without added salt, request lower-sodium options, or ask for the sauce to be on the side.
High Sodium Foods to Avoid
Here are some common culprits that are high in sodium:
- Processed meats: Deli meats, bacon, sausage, hot dogs.
- Canned goods: Soups, vegetables, beans (look for low-sodium or no-salt-added options).
- Frozen meals: Pizza, dinners, appetizers.
- Packaged snacks: Chips, crackers, pretzels.
- Fast food: Burgers, fries, pizza.
- Condiments: Soy sauce, ketchup, salad dressings.
- Cheese: Especially processed cheese.
Other Tips for Reducing Sodium Intake
- Use fresh ingredients or foods with no salt added.
- For favorite recipes, you may need to use other ingredients and delete or decrease the salt you would normally add. You can take salt out of most recipes, but don't try it if the recipe calls for yeast.
- Try orange or pineapple juice as a base for meat marinades.
- Avoid canned soups, entrees, and vegetables; pasta and rice mixes; frozen dinners; instant cereal; and pudding, gravy, and sauce mixes.
- Select frozen entrees that have fewer than 600 milligrams of sodium per serving (140 mg of sodium per serving is considered low sodium). Check the nutrition facts label on the package for sodium content. Limit yourself to one frozen entree per day.
- Use fresh, frozen, or no-added-salt canned vegetables. You can use low-sodium canned soups.
- Avoid mixed seasonings and spice blends that include salt, such as garlic salt.
- After about 2 weeks, your body will adjust and you will not miss the added salt in your diet.

Other Considerations
Managing Potassium, Phosphorus, and Protein
Depending on your kidney disease stage, you may also need to reduce the potassium, phosphorus, and protein in your diet.
- Phosphorus: Limit meat, dairy, beans, nuts, whole-grain bread, and dark-colored sodas.
- Potassium: Limit oranges, potatoes, tomatoes, whole-grain bread, and many other foods are high in potassium. Apples, carrots, and white bread are lower in potassium.
- Protein: Eat the right amount of protein. More protein than you need makes your kidneys work harder and may make CKD worse. But too little isn't healthy either.
Herbal Supplements and Vitamins
Herbal supplements aren't safe if you have kidney disease. Some can hurt your kidneys and even make kidney disease worse. Some vitamins can cause kidney problems too and should also be avoided.
Fluid Intake
If you're on dialysis, you may need to limit how much fluid you drink. Fluid can build up in your body between treatments.
Blood Sugar Management in Late-Stage CKD
Your blood sugar levels can actually get better with late-stage CKD. This may happen because of changes in how your body uses insulin. But when you're on dialysis, your blood sugar can increase. This is because the fluid used to filter your blood is high in glucose (sugar).
Additional Tips
- Be mindful of salt substitutes: If you have kidney issues, talk with your doctor before using a salt alternative, as your kidneys may have trouble processing potassium.
- Gradual reduction is key: Gradually decrease your sodium intake to allow your taste buds time to adjust.
- Stay hydrated: Drinking plenty of water helps your kidneys flush out excess sodium.
The Role of a Dietitian
Learning how to follow a low-sodium and diabetic diet can feel overwhelming. Talking with a registered dietitian can help you learn how to effectively improve your eating to support your health.
How a Dietitian Can Help
- Individualized meal planning.
- Recipe modifications to create delicious ways to keep eating your favorite foods.
