Understanding Daily Sodium Recommendations
To determine what's too much sodium in your soup, you must first understand the daily recommended limits for overall sodium intake. According to the U.S. Dietary Guidelines and the American Heart Association (AHA), the daily recommended limit is less than 2,300 mg for most adults. However, the AHA suggests an ideal limit of no more than 1,500 mg per day for most adults, especially those at risk of high blood pressure. This is about half of what the average American consumes daily. A high-sodium diet forces your body to retain water, increasing blood volume and placing more pressure on your blood vessels, which can lead to high blood pressure.
The Problem with Store-Bought Soups
Canned and pre-packaged soups are notoriously high in sodium, added for flavor and as a preservative. It is not uncommon for a single 1-cup serving of canned soup to contain 700-800mg of sodium, and since many cans hold at least two servings, eating the whole can can result in consuming 1,400-1,600mg or more. This could amount to more than half of your daily sodium target in one meal alone, leaving little room for other foods. Even soups labeled as "reduced sodium" can still contain significant amounts; a reduced-sodium version can have up to 25% less sodium than the standard version but may still be high. For this reason, it is crucial to read labels carefully and not rely solely on marketing claims.
The Health Risks of Excessive Sodium
Overconsumption of sodium over time can have severe health consequences. High blood pressure (hypertension) is a primary risk factor, which increases the likelihood of heart disease and stroke. Excess sodium also puts a strain on your kidneys, which filter excess sodium from the bloodstream, potentially leading to kidney disease. Additionally, high sodium intake is linked to an enlarged heart muscle, osteoporosis, and an increased risk of gastric cancer. Short-term effects include bloating and increased thirst. For individuals with pre-existing conditions like hypertension or kidney disease, a low sodium intake (closer to 1,500 mg) is even more important.
How to Control and Reduce Sodium in Your Soup
Managing the sodium content in your soup is achievable with a few simple strategies, whether you're buying it from a store or making it at home. The most significant control comes from cooking your own meals from scratch, but there are smart choices you can make for convenience foods as well.
Comparison of Soup Sodium Levels
| Soup Type | Typical Canned Sodium (per 1 cup) | Low Sodium Option (per 1 cup) | Homemade (per 1 cup) |
|---|---|---|---|
| Chicken Noodle | 800-900 mg | 390-480 mg | < 200 mg (depending on broth/seasoning) |
| Tomato | 650-960 mg | 380-480 mg | 50-200 mg (if using unsalted ingredients) |
| Minestrone | 480-700 mg | 470-480 mg | < 250 mg (using no-salt-added canned goods) |
| Lentil | 690 mg | 460 mg | < 150 mg (using dry lentils & herbs) |
Tips for a Healthier Bowl
For Store-Bought Soups:
- Read the Label: Look at the % Daily Value (%DV) for sodium. The FDA considers 5% or less to be low and 20% or more to be high. Aim for soups with a low %DV per serving.
- Dilute: If you buy a regular canned soup, you can dilute it with unsalted broth or water to reduce the overall sodium concentration.
- Rinse: If using canned beans or vegetables for an add-in, rinse them thoroughly to wash off some of the sodium from the packing liquid.
- Look for Claims: Seek out products labeled as "low sodium" (140mg or less per serving) or "no salt added". Be wary of "reduced sodium" and always check the nutrition facts.
For Homemade Soups:
- Use Unsalted Broth: The key to controlling sodium is starting with a low-sodium or unsalted stock or broth. There are many good options available, such as Pacific Natural Foods and Swanson unsalted stocks.
- Add Flavor with Herbs and Spices: Instead of relying on salt for flavor, use fresh herbs like thyme, rosemary, parsley, and basil, or dried spices like cumin, garlic powder, and onion powder.
- Incorporate Acid and Sweetness: A squeeze of lemon juice or a splash of vinegar can brighten flavors and cut through saltiness. A small amount of sugar or honey can also help balance a slightly oversalted soup.
- Season in Layers: Add salt gradually throughout the cooking process, tasting as you go. This prevents over-seasoning at the beginning, especially as the liquid reduces and flavors concentrate.
Conclusion
Ultimately, the question of how much sodium is too much in soup depends on your individual health needs and overall daily intake, but most commercial options far exceed healthy limits. By being mindful of serving sizes, reading nutrition labels, and making simple adjustments—especially opting for homemade versions with low-sodium ingredients and flavorful alternatives—you can enjoy a warm bowl of soup without compromising your health. Taking control of your sodium consumption is a powerful step towards better heart health and overall well-being.

How to fix salty soup: a quick guide
Lists of ways to fix salty soup
- Dilute with More Liquid: The simplest method is to add unsalted water or low-sodium broth to the soup.
- Bulk it Up: Add more low-sodium ingredients like vegetables, uncooked rice, or pasta, which can absorb some salt.
- Add an Acid: A splash of lemon juice or vinegar can balance the salty taste.
- Incorporate Dairy: Stirring in a small amount of unsalted cream, milk, or yogurt can mellow the saltiness in creamy soups.
- Use the Potato Trick (with caution): While debated, adding a raw, peeled potato can absorb some salt. It's not a magic cure-all, but it can help subtly.
Final Takeaway Points
Read Labels Carefully: Always check the nutrition facts for sodium content, not just the front-of-package claims like "reduced sodium". Choose Low-Sodium Broth: Starting with an unsalted or low-sodium broth is the most effective way to control the sodium in your homemade soup. Prioritize Homemade: Making soup from scratch gives you total control over the sodium content, allowing you to use flavorful herbs, spices, and acids instead of excessive salt. Know Your Limits: Remember the daily recommendations (typically <2,300mg, ideally <1,500mg) and be aware of how one bowl of soup can contribute significantly to your total. Rethink Servings: Be aware that a can of soup often contains more than one serving, so if you eat the whole can, you'll be consuming double or triple the sodium listed on the label.
Frequently Asked Questions
What are the health risks of eating too much sodium in soup?
Consuming excess sodium can increase your blood pressure, which is a major risk factor for heart disease and stroke. It also puts a strain on your kidneys and can cause fluid retention, leading to bloating.
Is it better to make my own soup to control sodium?
Yes, making your own soup at home gives you complete control over the ingredients, especially the sodium. You can start with unsalted broth and use fresh herbs and spices for flavor, which is significantly healthier than most canned options.
What do food labels like "low sodium" and "reduced sodium" mean?
According to the FDA, "low sodium" means the food contains 140 mg or less of sodium per serving. "Reduced sodium" means the product has at least 25% less sodium than the regular version, but it may still be high in sodium.
Can I remove salt from a soup that is already too salty?
You cannot entirely remove salt once it is dissolved. The most effective method is to dilute the soup by adding more unsalted liquid or other low-sodium ingredients. Some acidic or creamy additions can also help mask the salty flavor.
How can I make my soup flavorful without using a lot of salt?
To enhance flavor without salt, use herbs (fresh or dried), spices, garlic, onions, or a squeeze of lemon juice or vinegar. You can also build flavor by using unsalted broth and roasting your vegetables before adding them to the soup.
How much sodium does a typical canned soup contain?
A standard 1-cup serving of canned soup can contain anywhere from 600 to over 900mg of sodium, sometimes more. Since a can often holds two servings, this can easily equate to more than a day's worth of sodium in one sitting.
Is homemade soup always low in sodium?
No, homemade soup isn't automatically low in sodium. If you use salty ingredients like high-sodium broth, ham, or large amounts of pre-made seasoning packets, the sodium level can be high. The key is to consciously control the salt added during cooking.
