The Manufacturer's Stance: No Added MSG
First and foremost, Swanson explicitly states on its packaging and official website that it does not add monosodium glutamate (MSG) to its broth products. The company highlights its use of 100% natural, non-GMO ingredients, with no artificial flavors, colors, or preservatives. For consumers specifically seeking to avoid the direct addition of MSG, this is a clear and reassuring message.
The Fuller Picture: Natural Glutamates from Yeast Extract
This is where the conversation becomes more nuanced. While pure MSG is not added, the ingredient list on many Swanson broth varieties includes "Yeast Extract". Yeast extract is a common ingredient used in many foods to add a savory, umami flavor. The key takeaway is that yeast extract is a natural source of glutamates.
From a chemical perspective, the glutamate molecule found in yeast extract is identical to the glutamate molecule in added monosodium glutamate. The human body metabolizes both sources of glutamate in the exact same way. The distinction lies entirely in the source. Because the glutamate from yeast extract is considered naturally occurring, manufacturers are not required by the FDA to label it as "monosodium glutamate". For most consumers, the difference is trivial, but for those with a self-reported sensitivity to MSG, it is an important distinction to make. Many find that small amounts from natural sources do not trigger symptoms, but it is worth noting the ingredient's presence.
Decoding the Ingredients Label
Understanding the subtle differences in labeling is key for informed purchasing. When checking a carton of Swanson chicken broth, here's what to look for:
- No Added MSG: Look for the explicit "no added MSG" claim on the packaging, which Swanson prominently displays.
- Yeast Extract: Scan the ingredient list for "yeast extract," as this is the primary source of natural glutamates. Also be aware of other ingredients that may contain natural glutamate, though they are less common in broth, such as soy extracts or hydrolyzed protein.
- Natural Flavoring: The term "natural flavoring" is a broad category, but it can sometimes be used to describe flavors derived from natural sources that contain glutamates.
A Comparison of Broth Products
To help understand how Swanson compares to other brands and types, the following table breaks down key features. This is a simplified comparison, and specific ingredients can vary by product line, so always read the label.
| Feature | Swanson Chicken Broth (e.g., Regular) | Swanson Unsalted Chicken Broth | Pacific Foods Organic Chicken Broth | Homemade Chicken Broth |
|---|---|---|---|---|
| Added MSG? | No | No | No | No |
| Natural Glutamates? | Yes (Yeast Extract) | Yes (Yeast Extract) | Often has Yeast Extract | Yes (Naturally Occurring in Chicken/Veggies) |
| Sodium Level? | High | Low | Varies (often low-sodium options) | Completely Controllable |
| Artificial Flavors? | No | No | No | No |
| Control Over Ingredients? | No | No | No | Yes |
Beyond MSG: Other Factors to Consider
When evaluating Swanson chicken broth, there are other aspects to weigh beyond the glutamate question:
- Sodium Content: Standard Swanson chicken broth has a relatively high sodium content, which can be a concern for those watching their intake. Swanson does offer lower sodium and unsalted varieties.
- Container Concerns: For canned products, some groups like the EWG have raised concerns about potential BPA contamination from the can liners, though Swanson may use BPA-free options for some products.
- Flavor Profile: The presence of yeast extract adds a specific savory depth. Some consumers prefer the cleaner, more subtle flavor of a simple homemade broth made from meat, bones, and vegetables.
- Gluten-Free Status: For those with celiac disease or gluten sensitivity, it is important to note that while Swanson offers many gluten-free products, it is necessary to check the specific product label to ensure it is verified as gluten-free.
For the Home Cook: Alternatives to Consider
If you prefer to have complete control over your ingredients, or are very sensitive to natural glutamates, here are some alternatives:
- Make Your Own Broth: This is the most controlled option. Simmer chicken bones, meat, and vegetables like carrots, celery, and onions for a rich, flavorful broth without any additives.
- Opt for Bouillon: Bouillon cubes or granules can be a quick substitute, but be mindful that many contain MSG. Check the label carefully, especially if using a brand other than Swanson.
- Utilize Vegetable Stock: Use vegetable stock instead for a glutamate-free alternative.
- Add Flavor Naturally: Boost flavor in your recipes using ingredients like mushrooms, parmesan rinds, or tomatoes, which all contain natural glutamates.
Conclusion: Read the Label and Understand the Difference
In summary, Swanson chicken broth does not have monosodium glutamate (MSG) added as an ingredient. However, varieties that contain "Yeast Extract" will naturally contain glutamates, which provide a savory umami flavor. The human body does not differentiate between added MSG and naturally occurring glutamates, so for most, this is not an issue. For those who are particularly sensitive, checking the ingredients list for yeast extract is the most effective approach. Ultimately, understanding the ingredients is the best way to make the right choice for your diet and health needs.
