The use of wheat in Mexico varies greatly with latitude: the further south you go, the easier it becomes. Wheat is used much more in the north of the country. The staple food in Mexico is corn . Tortillas are as common in Mexico as bread is in the rest of North America or Europe. Corn tortillas are the most common in central- and south-Mexico; wheat tortillas are more common in north-Mexico. You should be careful everywhere you go though, as wheat tortillas can be found anywhere.
