Kidney Stone Prevention: Low Sodium (Salt) Recommendations
Last reviewed
The below recommendations are not applicable to all patients and all stone types. Please consult with your provider to determine if these suggested dietary adjustments are applicable to you and your stone.
Why does salt matter?
- It helps regulate water and other minerals in your body.
- The amount of sodium in urine affects calcium levels in urine. Lowering sodium helps lower the amount of calcium.
What should my salt intake be?
- The 2020 to 2025 Dietary Guidelines for Americans suggests less than 2,300 milligrams (mg) of salt each day.
- The American Heart Association suggests a limit of 1,500 mg each day for most adults.
How do I lower my salt intake?
- Eat more fresh foods. Limit processed, pre-made, and frozen foods. About 70% of your salt intake comes from these.
- Use less salt when cooking. Do not keep a saltshaker on the table at meals. Add flavors to your food without adding salt.
- Try salt free seasonings, such as garlic powder, onion powder, and black pepper.
- Use lemon juice, lime juice, or vinegar.
- Dry or fresh herbs add flavor. Try dill, basil, rosemary, dry mustard, and paprika.
- Check the nutrition label before buying foods. Look for food packages that say:
- Salt free or sodium free. This means it has 5 mg of salt or less per serving.
- Very low sodium. This means it has 35 mg of salt or less per serving.
- Low sodium. This means it has 140 mg of salt or less per serving
