Sensitivity notes

Why oxalates food checker matters

Oxalates are compounds found in many plant foods that can bind with calcium to form crystals. High oxalate intake may contribute to kidney stones in susceptible individuals and can cause other symptoms in those with oxalate sensitivity.

  • Stay well-hydrated to help prevent oxalate crystal formation
  • Pair high-oxalate foods with calcium-rich foods to bind oxalates
  • Cooking and boiling can reduce oxalate content in some foods
  • Spread oxalate intake throughout the day rather than one large dose
  • Consider probiotics - some gut bacteria break down oxalates

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
