Tortillas, a staple in Mexican cuisine, have gained immense popularity in the United States, with an increasing number of health-conscious options available. They are a thin flatbread traditionally crafted from either corn or wheat flour. This article aims to explore the nutritional aspects of corn tortillas, helping you make informed dietary choices.
The Essence of Corn Tortillas
Corn tortillas have deep roots, passed down from the Aztecs. Traditionally, their production begins with nixtamalization, a process where corn (maize) is soaked and cooked in an alkaline solution of calcium hydroxide (limewater). This softens the kernels and enhances the nutritional profile, increasing calcium, niacin, and resistant starch content. The corn is then stone-ground into masa (corn dough), shaped into thin disks, and baked.
Most commercially available corn tortillas are made using an industrial approach to nixtamalization. While traditional tortillas are 100% corn, mass-produced versions may include dehydrated corn flour (masa harina) with some wheat flour.
