What to know about corn tortilla
Corn tortillas are the reliable gluten-free wrap. Made from nixtamalized masa, corn cooked in limewater, they contain no wheat, so they are the standard swap for flour tortillas when you avoid gluten. They also test low FODMAP at normal servings, which is why a sensitive gut usually handles a couple of them where a wheat flour tortilla loaded with fructans would cause bloating. Nixtamalization even tames some of the lectins in corn, so a corn tortilla is gentler on the gut than raw cornmeal.
Watch for
- Genuinely wheat-free, but read the label: some tortillas sold as corn are actually corn-and-wheat blends, and shared production lines can mean cross-contact for celiacs
- Low FODMAP at one or two tortillas, making them a smart taco base when wheat flour tortillas upset your gut
- A refined-corn carb that sits on the SIBO borderline, so it is a neutral everyday staple rather than an anti-inflammatory food
