Corn vs. Flour: A Street Taco Tortilla Carb Comparison
When calculating the carb content of a street taco tortilla, the type of tortilla is the most important factor. Street tacos often use small, soft corn tortillas, though flour versions are also common. The ingredients, corn masa versus wheat flour, create a nutritional difference.
The Nutritional Details of Corn Tortillas
Many nutritionists consider corn tortillas healthier, because they're made from whole grains and go through nixtamalization. This process increases nutritional value, including niacin and calcium.
A standard serving of three small, 4-inch corn street taco tortillas from a major brand like Mission has approximately 19 to 20 grams of total carbohydrates. This number is consistent across brands and is due to the whole-grain corn masa. The fiber content is also beneficial, with roughly 2 grams per three-tortilla serving, which helps manage blood sugar. The net carbs for this serving are often around 17-18 grams.
The Carbohydrate Count in Flour Tortillas
Flour tortillas, made from refined wheat flour, usually have more carbohydrates than corn tortillas. The small street taco size can be misleading, as it is easy to eat more. Two Mission flour street taco tortillas have a carbohydrate count of 26 grams, which is higher than the carb count of three corn tortillas. The fiber content in regular flour tortillas is also lower, at only 1 gram per two-tortilla serving.
For low-carb diets, check the label. Many brands offer low-carb or "carb balance" flour tortillas that significantly reduce net carbs by using alternative flours or adding fiber. These are processed and may not offer the traditional street taco experience.
Factors That Influence a Tortilla's Carb Count
- Size: The size is the biggest factor. While street tacos use mini 4-inch tortillas, some restaurants or brands might use larger ones, increasing the carbohydrate count. Always check the nutrition label or ask about the size.
- Brand: Different brands use different recipes. The specific blend of flours, added ingredients, and processing can change the carb and fiber content. Check the nutrition facts for your preferred brand.
- Whole Wheat: Some flour tortillas use whole wheat flour. These can be a healthier alternative to white flour tortillas, providing more fiber. They will likely have more carbs than corn tortillas of a similar size.
Comparison Table: Corn vs. Flour Street Taco Tortillas

| Gluten-Free? | Yes | No |
Navigating Street Tacos on a Low-Carb Diet
Enjoying street tacos doesn't have to mean eating too many carbs. With a few changes, you can lower the carbs in your meal.
Choose Corn Tortillas over Flour
As the table shows, corn tortillas are better for lower carbs. They have fewer total carbs, and their higher fiber means fewer net carbs per serving. Their lower carb count also makes tracking your intake easier.
Embrace Low-Carb Tortilla Alternatives
For an even lower-carb option, consider almond flour tortillas or zero-carb street taco tortillas. These are designed for ketogenic and low-carb diets. While the taste and texture may vary, they offer a very low-carb option for fillings.
Build a Better Taco: Low-Carb Fillings
Your fillings are where you can most change the meal's carb count. Low-carb-friendly toppings and fillings include:
- Grilled chicken, steak, or fish
- Carnitas or shredded pork
- Shredded cheese
- Pico de Gallo (often zero or very low carb)
- Avocado or guacamole (adds healthy fats)
- Diced onions and cilantro
- Lettuce wraps (for a tortilla-free option)
Conclusion
In summary, the number of carbs in a street taco tortilla depends on its type and size. Traditional corn street taco tortillas have approximately 19 grams of carbohydrates per three-tortilla serving. Those on strict low-carb diets should use low-carb tortillas or lettuce wraps. By choosing your tortillas and fillings carefully, you can enjoy street tacos while following your dietary goals.
