Why lactose food checker matters
Lactose is the natural sugar in milk and dairy products. People with lactose intolerance lack sufficient lactase enzyme to digest it, leading to bloating, gas, and digestive discomfort after consuming dairy.
- Try lactose-free dairy products - they're real dairy with lactase added
- Hard aged cheeses are naturally lower in lactose
- Lactase enzyme supplements can help when eating dairy
- Yogurt and kefir may be better tolerated due to probiotics
- Your tolerance level is personal - some can handle small amounts

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
