Carbs by portion
| Portion | Total carbs | Fiber | Net carbs |
|---|---|---|---|
| 1 medium flour tortilla, 7-8 inch (49g) | 24.2g | 1.7g | 22.5g |
| 1 tortilla (117g) | 57.8g | 4.1g | 53.7g |
| 1 tortilla (48g) | 23.7g | 1.7g | 22.0g |
| 1 oz (28g) | 14.0g | 1.0g | 13.0g |
| 100 grams | 49.4g | 3.5g | 45.9g |
Net carbs
One medium flour tortilla has about 22g of net carbs, which is total carbs (24g) minus fiber (2g). The USDA data here is for standard flour tortillas. Corn tortillas have about 10 to 12g of net carbs per tortilla and more fiber. See the net carbs guide.
Glycemic index of a tortilla
The glycemic index of a tortilla is about 30. Flour tortillas have a surprisingly low glycemic index partly because the fat content (from lard or shortening) slows digestion, and the flour is not fully gelatinized the way it is in bread. Corn tortillas tend to have a similar or slightly higher GI.
For diabetes
One medium flour tortilla is about 24g of carbs. A burrito shell (10 inch) is about 35g of carbs before any filling. The low GI of 30 means the rise is slower than you might expect from a flour-based food. Still, two tacos in a medium tortilla is about 48g of carbs from the shells alone. Count the shell, the beans, and the rice as separate items. See the diabetes carb-counting guide.
Keto and low carb
One medium flour tortilla has about 22g of net carbs, which fills most of a strict keto day's budget. Flour tortillas do not fit keto. Low-carb tortilla alternatives made with almond flour or psyllium husk typically have 4 to 6g of net carbs, but read labels carefully.
Good to know
Flour tortilla size varies widely. A small street taco tortilla (about 30g) has roughly 15g of carbs. A large burrito wrap (about 72g, 10-inch) has about 36g. The tortilla is often the single biggest carb contributor in a taco or burrito meal, bigger than the rice or beans if they are kept to a moderate portion. Corn tortillas are lower in carbs and higher in fiber than flour tortillas of the same diameter.
