Nutritional Showdown: Corn vs. Flour Tortillas
When evaluating which has lower carbs, flour or corn tortillas, it's essential to consider the full picture, including serving size and ingredients. While corn tortillas often get the nod for being the healthier, lower-carb option, the reality depends on the specific product and how it's prepared.
The Carbohydrate Breakdown
In a side-by-side comparison of similar weights, a corn tortilla typically contains fewer carbohydrates than a flour tortilla. For example, the USDA data, as summarized by Food Network, shows that a 48g serving of two corn tortillas contains about 22g of total carbs, while a 48g serving of one flour tortilla contains around 23.7g of total carbs. However, a key distinction lies in the standard portion sizes. Corn tortillas are traditionally smaller, often used for tacos, while flour tortillas are larger and used for burritos. A single large flour tortilla can therefore have a significantly higher carb count than the two smaller corn tortillas commonly eaten in a meal.
Fiber, Fat, and Calories
The nutritional differences extend beyond just carbs. Corn tortillas are made from whole grain corn, which is a key factor in their health benefits. This makes them higher in fiber and lower in fat and calories than their flour counterparts. Flour tortillas, conversely, often use refined wheat flour and contain fat from sources like vegetable shortening or lard, increasing their calorie and fat content.
For those managing blood sugar, the higher fiber content in corn tortillas is a benefit, as fiber helps to slow digestion and prevent sudden blood sugar spikes. Flour tortillas can be made healthier by opting for whole wheat varieties, which boost their fiber and nutrient content.
Ingredients and Dietary Considerations
Flour tortillas often have more ingredients than corn tortillas, which are typically made from just masa harina (ground corn), water, and salt. This difference in composition is important for those with specific dietary needs.
- Gluten-Free: Corn tortillas are naturally gluten-free, making them a safe choice for individuals with celiac disease or gluten sensitivity. Flour tortillas contain gluten from the wheat flour and must be avoided by those with gluten-related conditions.
- Sodium: Standard flour tortillas often contain a much higher sodium content than corn tortillas, where salt is typically used more minimally. This is an important consideration for individuals managing blood pressure.
- Fortification: While corn tortillas naturally contain some vitamins and minerals from the nixtamalization process, flour tortillas are often fortified with added iron and B-vitamins.
Corn Tortillas vs. Flour Tortillas: At a Glance
| Nutrient (per 48g serving) | Corn Tortillas (Two Small) | Flour Tortillas (One Medium) |
|---|---|---|
| Calories | 105 kcal | 147 kcal |
| Total Carbohydrates | 22 g | 23.7 g |
| Dietary Fiber | 3 g | 0.68 g |
| Total Fat | 1.2 g | 3.84 g |
| Protein | 2.7 g | 4 g |
| Sodium | 21.6 mg | 353 mg |
Culinary Usage and Portion Control
Beyond nutrition, the ideal choice depends on your culinary purpose. Corn tortillas are traditionally used for tacos due to their smaller size and distinct earthy flavor. They are more delicate and prone to breaking, making them less suitable for large, heavily filled items. Flour tortillas are prized for their softness, pliability, and sturdiness, which makes them ideal for burritos, enchiladas, and quesadillas.
Regardless of your choice, portion control is paramount. A single burrito-sized flour tortilla will contain far more calories and carbs than the several small corn tortillas that might be used for tacos. Pairing any tortilla with plenty of lean protein, healthy fats like avocado, and fiber-rich vegetables is the best way to create a balanced, nutrient-dense meal.
Conclusion: Which is the Healthier Choice?
For those focused strictly on a lower carbohydrate count and fewer calories per serving, corn tortillas generally come out ahead, especially given their higher fiber and lower fat and sodium content. They are also the definitive choice for those on a gluten-free diet. However, if a recipe calls for the unique pliability and strength of a flour tortilla, opting for a whole wheat variety is a healthier compromise that boosts fiber and nutritional value. Ultimately, both types can be part of a healthy diet when enjoyed in moderation and paired with nutritious, whole-food fillings. The best tortilla is the one that best fits your dietary goals and taste preferences.
For a delicious, healthier version of your favorite dishes, explore making your own tortillas from scratch using whole wheat flour or nixtamalized corn masa.

Low-Carb Tortilla Alternatives
For those adhering to very low-carb or ketogenic diets, even corn tortillas can be too high in carbs. Fortunately, several specialty and homemade options exist:
- Almond Flour Tortillas: Recipes using almond flour provide a very low-carb, gluten-free alternative.
- Keto Tortillas: Specialty recipes can utilize ingredients like psyllium husk powder, flaxseed, and coconut flour to create low-carb tortillas.
- Cheese-based Tortillas: Some keto recipes use melted cheese to create a pliable, low-carb base for wraps.
