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

Serving size, prep, and portion notes for corn
Corn is naturally gluten-free, so the common worry that it contains gluten is a myth, though corn products milled in wheat facilities can pick up gluten by cross-contact. The real triggers are different: corn is high in free glutamates, the same savory compound behind MSG reactions, and moderately high in salicylates. It is also high in lectins and sits on the pro-inflammatory side, which is why some people feel bloated or headachy after corn even though it passes as a safe grain.
Watch for
High in free glutamates, so it can provoke the same headaches or flushing that people blame on MSG / Moderately high in salicylates, a trigger if you react to aspirin or salicylate-rich foods / High in lectins, which can bother people who are sensitive to them / Naturally gluten-free, but processed corn products can be cross-contaminated with wheat, so check labels if you have celiac disease
