Most commercial canned or packaged chicken broths are surprisingly high in sodium, with levels often ranging from 700 to 900 milligrams per cup. This high salt content is added primarily for flavor enhancement and as a preservative, making the product more appealing to consumers and extending its shelf life. For someone on a regular diet, just one cup of broth can represent a significant portion of their recommended daily sodium limit. For those with health conditions requiring low-sodium diets, this poses a considerable challenge.
Why is there so much sodium in chicken broth?
The high sodium content in many store-bought chicken broths isn't an accident; it's a deliberate part of the manufacturing process.
- Flavor enhancement: Sodium is a powerful flavor enhancer that makes the broth taste rich and savory, even if it is made with lower-quality ingredients. It can also block bitter notes that naturally occur in the broth.
- Preservation: Salt has been used for centuries to preserve food. Its high concentration in broth inhibits microbial growth, allowing the product to remain shelf-stable for long periods.
- Consistency and binding: In some cases, especially with powdered bouillons or concentrated bases, sodium and other binding agents help create a consistent product.
The difference between homemade and store-bought broth
When you make broth at home, you have complete control over the ingredients, including how much (if any) salt is added. This allows you to create a much healthier product while still extracting rich flavors from the chicken bones, meat, and vegetables. Homemade broth can have a naturally rich, complex flavor without the need for excessive sodium.
Comparison Table: Homemade vs. Store-Bought Broth
| Feature | Homemade Chicken Broth | Store-Bought Chicken Broth | 
|---|---|---|
| Sodium Content | Fully controllable (can be salt-free) | Often very high in sodium; low-sodium options available | 
| Flavor Control | Customize herbs, spices, and vegetable ratios | Flavor profile is pre-determined by the manufacturer | 
| Ingredients | Use fresh vegetables, herbs, and chicken parts | May contain artificial flavors, yeast extract, or MSG | 
| Cost | Often cheaper, using leftover bones and scraps | Priced for convenience, can be more expensive long-term | 
| Health Benefits | Naturally rich in gelatin and controlled nutrients | Less nutritious due to processing and high sodium levels | 
| Shelf Life | Refrigerate for up to a week, freeze for months | Stable for months or years unopened | 
Health implications of high-sodium intake
Excessive sodium consumption is a well-documented risk factor for several serious health issues, particularly for people with hypertension or other cardiovascular concerns.
Cardiovascular health
High sodium intake can lead to water retention, which increases blood volume and puts extra strain on the heart and blood vessels. This can lead to elevated blood pressure, increasing the risk of heart disease and stroke over time.
Kidney health
The kidneys play a vital role in balancing sodium levels in the body. Overloading them with excess sodium can impair their function, especially for individuals with existing kidney disease.
Stomach cancer
Some research has suggested a link between excessive sodium consumption and an increased risk of developing stomach cancer.
How to make a low-sodium choice
If you want to reduce sodium intake without giving up chicken broth, you have several options:
- Choose "low-sodium" or "no-salt-added" versions: Many brands now offer low-sodium varieties. Read the labels carefully; "low-sodium" products must contain 140 mg or less of sodium per serving. Some brands also offer "no-salt-added" options for maximum control.
- Make your own broth: As the comparison table shows, making your own broth from scratch is the best way to control sodium. You can use chicken bones, vegetable scraps (onions, carrots, celery), and fresh herbs.

- Dilute regular broth: If you can't find low-sodium broth, you can dilute regular broth with water. This will reduce the sodium concentration per serving, though it may also weaken the flavor.
- Use concentrated bases sparingly: Some products, like Better Than Bouillon, offer low-sodium chicken bases. These are very potent, so a little goes a long way. Using them in moderation can help you manage sodium intake.
Conclusion
Yes, standard commercial chicken broth typically has a high sodium content, which serves to enhance flavor and prolong shelf life but can contribute to health risks associated with excessive sodium intake. However, consumers have excellent alternatives to reduce their consumption, from opting for low-sodium packaged versions to preparing flavorful, salt-free broth from scratch at home. Ultimately, managing sodium levels in your diet is about awareness and making informed choices, and understanding the sodium content of a staple like chicken broth is a great place to start.
