Understanding the Salt in Tomato Paste
Tomato paste is a concentrated product made from cooked tomatoes, with the seeds and skin removed. While plain, unsalted tomatoes are naturally low in sodium, the concentration process often involves adding salt for flavor enhancement and preservation, which can significantly increase the sodium level in the final product. This is why the question, "Is tomato paste high in sodium?" doesn't have a simple yes or no answer. The key lies in understanding the difference between standard and 'no salt added' varieties and knowing how to read the nutrition label.
The Hidden Sodium in Standard Tomato Paste
Standard, store-bought tomato paste is often a hidden source of sodium. A single 1-tablespoon serving can contain about 9.4mg of sodium, but since it's a concentrated ingredient, it's easy to use more than one tablespoon in a recipe. For a larger reference, a 100g serving of standard tomato paste contains about 59mg of sodium, which is 3% of the daily recommended value. While this might seem low, remember that this is a small amount of a concentrated ingredient that is often added to dishes that already contain other sodium-rich ingredients. When adding a whole 6-ounce can to a sauce, the total sodium contribution from the paste alone can become substantial.
How to Decode the Label for Low-Sodium Options
Fortunately, for those monitoring their salt intake, many brands offer a "no salt added" version of tomato paste. These products rely on the natural, rich flavor of tomatoes and often contain a negligible amount of sodium. It is crucial to always check the nutrition facts label, as sodium levels can vary widely. According to the NHLBI, foods with 5 percent or less of the Daily Value for sodium per serving are considered low. When comparing products, use this percentage to quickly assess and choose the healthiest option. Also, consider the serving size listed on the label, as a small serving size can sometimes mask a higher sodium density.
Comparison: Regular vs. No Salt Added Tomato Paste
| Feature | Regular Tomato Paste | No Salt Added Tomato Paste |
|---|---|---|
| Sodium Content (per 100g) | Approx. 59mg | As low as 20mg or less |
| Flavor Profile | Rich and savory, with salt added to enhance taste | Unadulterated, pure tomato flavor, slightly more acidic |
| Preservation | Salt often acts as an additional preservative | Rely on the cooking and canning process for preservation |
| Best For... | Recipes where you don't mind adding a pre-seasoned element, or need a flavor boost | Health-conscious cooking, homemade recipes where you control the seasoning |
| Overall Health Impact | Can contribute significantly to daily sodium intake | Much healthier for those watching their sodium levels |
Benefits of Using No Salt Added Tomato Paste
Using the no-salt-added variety provides several health and culinary benefits:
- Better Control: You have complete control over the amount of salt in your recipes. This is ideal for those with high blood pressure or other health concerns.
- Pure Flavor: The unadulterated tomato flavor shines through, allowing you to appreciate the natural taste of the ingredient.
- Flexibility: It gives you the freedom to build flavors with herbs and spices rather than relying on a salty base.
Practical Ways to Reduce Sodium in Your Recipes
If you only have regular tomato paste on hand, or are looking for other ways to reduce sodium, here are some helpful tips:
- Start with Less: Use half the amount of regular tomato paste and supplement with another tomato product, like no-salt-added diced tomatoes or fresh tomatoes.
- Add Other Flavor Boosters: Use herbs, spices, garlic, onions, or a splash of vinegar to enhance flavor without adding salt. Cooking with aromatics can create a richer, deeper flavor profile.
- Make Your Own: For ultimate control, consider making your own tomato paste at home. It allows you to add as much or as little salt as you desire, or none at all. You can find easy recipes online that require only tomatoes and an oven or stovetop, like this one from Food Network.
- Use Water to Dilute: For sauces and soups, you can reduce the amount of tomato paste and use water or a low-sodium broth to thin the consistency, minimizing its sodium contribution.
Conclusion: The Final Verdict
In short, while tomato paste itself is not inherently high in sodium, many conventional varieties are processed with added salt, which can significantly raise the sodium content of your dishes. The solution is to be a vigilant consumer by checking nutrition labels and opting for "no salt added" options whenever possible. By taking control of the ingredients you use, you can enjoy the rich, concentrated flavor of tomato paste while keeping your sodium intake in check. For those concerned with their heart health or simply looking to eat cleaner, this simple swap is a powerful step toward healthier cooking.

Final Takeaways
- Read the Label: Always check the nutrition facts, especially the sodium per serving and the Daily Value percentage.
- Choose 'No Salt Added': Opt for the low-sodium or 'no salt added' version for the healthiest choice, giving you control over seasoning.
- Sodium is Added: The salt in standard tomato paste is added for flavor and preservation, not naturally occurring in high amounts.
- Don't Judge by Serving Size: Be wary of products showing low sodium for a small serving size, as you may use much more in a full recipe.
- Homemade is Best: Making your own tomato paste is the best way to ensure there is no added sodium.
- Reduce and Season Differently: If using regular paste, use less and rely on other herbs and spices to build flavor.
Practical Application
- For Sauces and Stews: Use a no-salt-added paste and build flavor with roasted garlic, onions, and fresh herbs.
- For Flavor Base: For browning tomato paste to enhance flavor, start with a no-salt-added variety to control the saltiness from the beginning.
- For Last-Minute Fixes: If you accidentally use regular paste and your dish is too salty, consider adding a potato or a little sugar to balance the flavors, but the best approach is prevention.
Final Summary
Your standard tube or can of tomato paste often contains added sodium for flavor and preservation. However, numerous brands offer a 'no salt added' alternative which contains very little sodium, derived only from the tomatoes themselves. By reading nutrition labels and actively seeking low-sodium versions, you can use tomato paste as a rich, flavorful ingredient in your cooking without significantly increasing your sodium intake. For maximum control, a homemade paste is the most reliable option.
