Understanding the Sodium in Your Taco Shells
While many people believe corn tortillas are a low-sodium choice, the sodium content in a hard-shelled corn taco can vary dramatically. This difference is primarily due to the manufacturing process, added ingredients, and whether the shell is fried. The journey from a soft corn tortilla to a crispy, ready-to-eat taco shell often involves adding salt for flavor and preservation.
Store-Bought vs. Homemade Corn Taco Shells
There is a significant and important distinction between store-bought and homemade taco shells when it comes to sodium. A fresh corn tortilla, the base for a corn taco shell, naturally contains very little sodium. When made at home from masa harina, water, and a pinch of salt, the sodium content is minimal and fully controlled by the cook. However, the process for creating a commercial, shelf-stable, hard taco shell involves different ingredients and techniques.
Commercial producers add salt for multiple reasons:
- Flavor enhancement: Salt is added to make the otherwise bland corn flavor more appealing.
- Preservation: Sodium acts as a preservative, extending the shelf life of the packaged shells.
- Processing aid: Salt can influence the texture and pliability of the finished product.
Factors Influencing Sodium Content
Several factors contribute to the final sodium count listed on a taco shell's nutritional label:
- Brand and Recipe: Each brand uses its own proprietary recipe. Brands like Ortega and Old El Paso, for instance, have different sodium levels per shell.
- Size: Larger taco shells will naturally contain more sodium than smaller, miniature versions, even from the same brand.
- Frying Process: Some manufacturers fry their shells in oil, and salt is often sprinkled on immediately after frying to make it stick. This adds another layer of sodium not found in a fresh, un-fried tortilla.
Sodium Levels in Popular Corn Taco Shells
To illustrate the variability, here is a comparison of different corn taco shells based on available nutritional data. Note that serving sizes can also vary, so always check the product's packaging.
| Brand/Type | Serving Size | Approximate Sodium (mg) | Source |
|---|---|---|---|
| Signature SELECT (Jumbo) | 1 Shell | 25 mg | |
| Ortega (Yellow Corn) | 2 Shells | 160 mg | |
| Old El Paso (Crunchy) | 3 Shells | 125 mg | |
| Generic/Homemade (Miniature) | 1 Shell | ~23 mg | |
| Simple Truth Organic | 1 Shell | 0 mg |
Note: Values for commercial brands may change based on product updates. Always consult the most recent packaging for the most accurate information.
What About the 0mg Sodium Shells?
Some nutritional labels may report 0mg of sodium, like the Simple Truth Organic example. This is most often the case for plain corn tortillas rather than hard-fried shells, which are typically very low in salt. For a hard shell to have zero sodium, no salt would have to be added during manufacturing, making it a very specific and less common product.
How to Minimize Sodium When Making Tacos
For those watching their sodium intake, there are several simple strategies to keep your tacos healthy:
- Choose the right shell: Opt for low-sodium or no-salt-added store-bought shells. For ultimate control, use plain corn tortillas and either bake them or toast them lightly in a pan without added salt.
- Make your own shells: The simplest and most effective way to control sodium is to make your own hard shells. All you need is masa harina, water, and a press. You control the amount of salt, if any, that goes in.
- Rinse canned ingredients: If using canned beans, corn, or other ingredients, rinse them thoroughly under cold water. This can reduce the sodium content by up to 40%.
- Use natural flavor enhancers: Rely on a variety of spices like cumin, chili powder, and paprika, as well as fresh herbs such as cilantro, instead of relying on heavily salted seasoning packets.
- Be mindful of other ingredients: Condiments and toppings can hide a lot of sodium. Choose low-sodium salsas, make your own guacamole from fresh ingredients, and be sparing with salted cheese.
The Health Impact of Excess Sodium
Consuming too much sodium has been linked to numerous adverse health outcomes. The World Health Organization recommends adults consume less than 2,000 mg of sodium per day, equivalent to just under a teaspoon of salt. The average American, however, consumes significantly more. A high-sodium diet is a major contributing factor to high blood pressure, which increases the risk of cardiovascular diseases, stroke, and kidney disease. Controlling the sodium in foundational ingredients like taco shells is an excellent starting point for reducing overall intake.

Conclusion
The sodium content in a corn taco shell is not a fixed number, but a variable dependent on brand, size, and preparation method. While plain corn tortillas are naturally low in sodium, commercially produced hard shells can contain a significant amount due to added salt for flavor and preservation. The good news is that by making informed choices, such as checking nutrition labels, choosing low-sodium brands, or preparing your own shells at home, you can easily manage the sodium in your tacos. This simple step contributes to better overall health and allows for a more flavorful, conscious approach to your meals.
