The Sodium Content of Subway American Cheese
For a standard 6-inch sub, adding American cheese contributes approximately 210 milligrams (mg) of sodium. This figure is based on a standard two-triangle serving of the processed American cheese used by Subway. While this might seem moderate on its own, it's important to consider that this is a single ingredient in a sandwich that also contains sodium in the bread, meats, and sauces. For someone trying to limit their daily sodium, which the American Heart Association recommends as a maximum of 2,300 mg per day for healthy adults, this one ingredient represents a meaningful contribution.
Factors Influencing Processed Cheese Sodium
Processed American cheese differs from natural cheese in both its production and ingredients, which directly impacts its sodium levels. The inclusion of sodium-based additives is crucial for achieving its signature smooth texture and long shelf life. For instance, the ingredients list for Subway's American cheese includes sodium citrate and salt, both of which increase the overall sodium content.
A Deeper Look at Processing
- Emulsifying Agents: Additives like sodium citrate are used to prevent the cheese from separating and to create a uniform, meltable product. These agents, by their nature, are sodium-rich.
- Preservatives: Sodium-containing preservatives, such as sorbic acid, are included to inhibit mold growth and extend the shelf life of the product.
- Flavor Enhancement: Salt is added for flavor, a standard practice in cheesemaking, but processed cheese often relies on it more heavily for taste than its natural counterparts.
Subway Cheese Sodium Comparison
When building a sandwich, choosing a different cheese can significantly lower the final sodium count. Here is a comparison of the approximate sodium content per 6-inch serving for various Subway cheese options, based on recent nutritional data:
| Cheese Option | Approximate Sodium (per 6-inch sub) |
|---|---|
| American Cheese | 210 mg |
| Pepperjack | 140 mg |
| Cheddar | 95 mg |
| Provolone | 50 mg (older data suggests ~248mg, use caution) |
| Swiss | 35 mg |
Note: Nutritional information can vary by region and over time. The figures are intended for comparison purposes. This comparison table clearly illustrates that Swiss cheese is the most low-sodium option available at Subway, while Provolone can be a lower alternative to American, though nutritional data should be checked for the most recent values.
Smart Strategies for Lowering Sodium at Subway
For those who enjoy Subway but need to watch their sodium intake, several strategies can help manage the salt content of your meal. The cumulative effect of ingredients can add up quickly, so making informed choices is crucial.
Practical tips for a low-sodium sub:
- Choose the right cheese: As the comparison table shows, opting for Swiss cheese is the simplest way to reduce sodium from your cheese choice.
- Load up on fresh vegetables: All of Subway's fresh vegetables—including lettuce, tomatoes, cucumbers, and onions—are naturally low in sodium. Piling them on adds flavor, nutrients, and volume without contributing significant salt.
- Be selective with sauces and dressings: Many sauces are packed with sodium. For example, some dressings or sauces can add hundreds of milligrams of sodium. The best low-sodium choices are simple oil and vinegar.
- Rethink the meat: Some meats are higher in sodium than others. When building a custom sandwich, be mindful of options like processed Italian meats, which are typically high in sodium, versus choices like oven-roasted chicken or roast beef.
- Portion control: Ordering a 6-inch sub instead of a footlong automatically cuts the sodium content of all ingredients in half. This is a straightforward and effective way to manage intake.
The Health Context of Sodium
Excessive sodium intake is linked to high blood pressure, a major risk factor for heart disease and stroke. While enjoying a Subway sandwich with American cheese occasionally is fine for most people, those with specific health conditions such as hypertension, heart failure, or kidney issues should be more vigilant about their sodium consumption. The information provided here helps in making those informed decisions.

Conclusion
The American cheese at Subway adds a significant amount of sodium to any sandwich, contributing approximately 210mg for a standard 6-inch serving. For those monitoring their salt intake, it's wise to consider lower-sodium alternatives like Swiss cheese (35mg) or Cheddar (95mg). By making careful choices with cheese, sauces, and portion sizes, it is possible to enjoy a Subway meal while keeping sodium levels in check. Understanding the nutritional impact of each ingredient is the first step towards a healthier, more balanced diet.
