What to know about corn flour
Corn flour, cornmeal and masa are naturally gluten-free, which makes them a go-to for baking, breading and thickening when wheat is off the table. The milled corn itself is clean on histamine, salicylates, FODMAPs and the other common food-chemistry triggers, so the real questions are not about a reaction to the flour. Two things are worth knowing: whole-ground corn flour is fairly high in lectins, and packaged corn flour is often milled alongside wheat, so cross-contact can quietly undo the gluten-free advantage if you have celiac disease.
Watch for
- Naturally gluten-free, but frequently milled in facilities that also handle wheat, so look for a certified gluten-free label if you have celiac disease or react to trace gluten
- Whole-ground corn flour is fairly high in lectins, which can unsettle a sensitive gut; thorough cooking lowers them
- A refined starch that sits on the SIBO borderline and is mildly pro-inflammatory, so treat it as a background carb rather than a gut-calming choice
