Why Canned Foods Contain High Sodium
Salt, or sodium chloride, is added to many canned goods for several key reasons, including preservation and flavor enhancement. For decades, it has been a reliable, inexpensive preservative, preventing the growth of bacteria and ensuring products remain safe for long-term storage. However, this practice often results in canned foods containing a significantly higher sodium content compared to their fresh or frozen counterparts. While convenient, this added sodium can contribute to health issues like high blood pressure for some individuals.
Practical Methods for Reducing Sodium
Fortunately, it is possible to drastically reduce the sodium content of canned foods without sacrificing convenience. The most effective methods involve simple preparation steps that you can incorporate into your cooking routine.
1. Draining and Rinsing
This is the simplest and most effective technique for vegetables, beans, and some meats. The process involves two steps to maximize sodium removal.
- Step One: Drain. Open the can and pour the contents into a colander or fine-mesh sieve over the sink. Allow all the canning liquid to drain away completely. A significant portion of the sodium is dissolved in this brine.
- Step Two: Rinse. After draining, hold the colander under cool, running water. Toss and rinse the food for at least 30 seconds, or until the water runs clear. Studies show that draining and rinsing can decrease sodium in beans by up to 43% and vegetables by up to 23%.
2. Diluting with Other Ingredients
For canned foods where rinsing isn't an option, like soups or sauces, dilution is a great alternative. By adding low-sodium or salt-free ingredients, you can spread the sodium content over a larger volume, reducing the per-serving amount. For example, if a canned soup is too salty, you can add some unsalted broth, water, or extra vegetables to the pot. This approach also works well for canned tomatoes or chilis.
3. Using Acidic or Flavorful Additions
Enhancing dishes with other flavors can distract your palate from the absence of salt, or even counter the salty taste. Instead of relying on salt for flavor, use other ingredients to create a more complex, satisfying profile.
- Acidic ingredients: A squeeze of lemon or lime juice or a splash of vinegar can brighten a dish and balance a salty taste.
- Herbs and spices: Fresh or dried herbs like parsley, oregano, or basil, along with spices such as garlic powder, onion powder, or paprika, add layers of flavor without any sodium.
- Roasting vegetables: For soups, roasting vegetables like onions, carrots, and potatoes before adding them can create a rich, caramelized flavor that reduces the need for added salt.
4. The Potato Trick (for Soups and Stews)
This old-fashioned method can help draw out excess salt from a liquid-based dish. To do this, simply add a peeled, halved, or thickly sliced potato to the pot while simmering. The starchy potato will absorb some of the excess sodium from the cooking liquid. Once the potato is cooked and has done its job, remove it before serving.
Comparison of Sodium Reduction Techniques
| Technique | Canned Food Type | Effectiveness | Best For | Considerations |
|---|---|---|---|---|
| Draining & Rinsing | Beans, vegetables, tuna in brine | High (up to 43% for beans) | Legumes, corn, peas, tuna | Flavor can be washed away with salt; simple and quick. |
| Dilution | Soups, sauces, broths | Moderate (depends on dilution ratio) | Canned soups, tomato sauces | May require adjusting consistency with thickeners. |
| Adding Acid | Any dish | High (flavor balancing) | Finishing touch for soups, stews, sauces | Taste preference is subjective; use in small amounts. |
| Flavorful Herbs/Spices | Any dish | High (alternative flavor source) | Most recipes with canned ingredients | Requires knowledge of flavor pairings. |
| The Potato Trick | Soups, stews | Moderate (absorbs excess salt) | Soups, hearty stews | Requires a longer simmer time; potato must be removed. |
Making Conscious Choices at the Store
The best way to reduce sodium is to choose low-sodium options from the start. Many canned goods now come in varieties labeled as "no salt added" or "low sodium". While these may not be completely sodium-free, they contain significantly less sodium than their regular counterparts. Read the nutrition label carefully, paying attention to the milligrams of sodium per serving and the serving size. You can also opt for frozen vegetables, which are often packed without added salt, or use fresh produce whenever possible.
Conclusion: Simple Steps, Big Impact
Reducing the sodium in canned food is an achievable goal that can have a positive impact on your health. By incorporating simple steps like draining and rinsing, using low-sodium versions, and adding other flavorful ingredients, you can enjoy the convenience of canned goods without the excessive salt. These small adjustments can lead to a healthier diet and a more mindful approach to cooking.
Beyond the Can: A More Mindful Approach
Adopting these practices can also inspire broader healthy cooking habits. You'll become more aware of how much sodium is in processed foods and more confident in creating delicious, healthier meals from scratch or with less salt. As your taste buds adjust over time, you may find that you prefer the natural, vibrant flavors of food that aren't masked by excess salt.

Important Considerations
While these methods are effective, remember that they work best in conjunction with a generally healthy diet. Consuming a variety of fresh foods and limiting other high-sodium culprits like processed meats and pre-packaged meals is key for overall wellness. Consistency is important, but making a conscious effort to apply these strategies even most of the time is a great starting point for anyone looking to improve their health.
Final Thoughts
Ultimately, the goal isn't to demonize canned food but to use it wisely. With these simple tips and a little practice, canned goods can remain a convenient and healthy part of your diet, helping you reduce your sodium intake one meal at a time.
How to get rid of sodium in canned food: the takeaway
Taking a few extra minutes to drain and rinse canned foods can dramatically cut your sodium intake. Combining this practice with using low-sodium products and flavoring dishes with herbs and spices will result in a healthier, more flavorful meal.
