Corn tortillas are a kidney stone staple: 1 mg oxalate each, cheap, and the foundation of an entire cuisine. Tacos with grilled chicken or fish, topped with onion, cilantro, and a squeeze of lime — that's a meal under 5 mg total oxalate. Flour tortillas are similarly low in oxalate. The tortilla itself is never the oxalate problem in a Mexican meal. It's what you put inside (watch for excessive cheese sauce sodium, skip spinach fillings) and how many you eat.
