What is the difference between blue and white tortillas?
White tortillas are 75% starch, while blue tortillas are only 68%. They lower the glycemic index (GI). This indicator evaluates carbohydrates according to their effects on blood sugar levels.
Blue corn, known for its distinctive color, offers several health benefits thanks to its high content of anthocyanins, which are antioxidants. These antioxidants may help reduce the risk of chronic diseases, such as heart disease and diabetes, and have also been associated with anticancer and anti-inflammatory properties. Additionally, blue corn typically has a lower glycemic index than white corn, which means it can help regulate blood sugar levels and reduce glucose spikes.
To identify if a tortilla is made from authentic blue corn, you can use a simple trick: squeeze a little lemon over it. If the tortilla turns a pink or purple hue, it’s likely made from natural blue corn, as citric acid reacts with anthocyanins, the natural pigments in blue corn. If it doesn’t change color, or turns gray, it’s likely a blue-painted tortilla.
