Blue corn tortillas are a traditional Mexican flatbread made from masa harina ground from blue corn, a variety of maize with a deep purple-blue hue. They are typically made with just blue corn flour, water, and a pinch of salt, and are a staple in Southwestern U.S. and Mexican cuisine. Their distinctive color comes from natural anthocyanin pigments in the corn's hull.
These tortillas are a moderate source of complex carbohydrates and provide a good amount of dietary fiber, with a modest amount of plant-based protein. A single tortilla typically contains around 50-70 calories, making it a lighter alternative to many grain-based breads.

The blue color is due to anthocyanins, the same powerful antioxidants found in blueberries and red cabbage. Nutritionally, blue corn has been shown to have a lower glycemic index than white or yellow corn, which may help in managing blood sugar levels.
