Carbohydrates in tortillas vary slightly, depending on if you have a flour or corn tortilla. You get approximately 14.5 grams of carbohydrates from a medium 6-inch flour tortilla or 14 grams from a similar size corn tortilla. A medium 6-inch flour tortilla has a total of about 90 calories and nearly 70 percent of the calories come from carbohydrates.
If you eat two 6 flour tortillas (220 calories, 42 grams of carbohydrate) this is NOT the same as consuming two 10 flour tortillas (346 calories and 66 grams of carbohydrate). Flour tortillas tend to have more carbohydrate than corn tortillas of the same weight. If you eat one 10 flour tortilla, you have consumed 173 calories and 33 grams of carbohydrate (2 carbohydrate exchanges). If you consume three 6 corn tortillas, you will have taken in 150 calories and the same amount of carbohydrate (33 grams) as the one 10 flour tortilla. Also, hard-shell tortillas, which have typically been fried in oil, will have more fat and calories than a soft tortilla of the same weight.
