Sensitivity notes

Why low fermentation food checker matters

SIBO (Small Intestinal Bacterial Overgrowth) diets focus on reducing fermentable foods that feed bacteria in the small intestine. Low-fermentation foods help manage symptoms like bloating, gas, and abdominal discomfort.

  • Low-fermentation eating reduces food for overgrown bacteria
  • Meal spacing (4-5 hours) allows the MMC to clear the gut
  • Avoid grazing - structured meals are better
  • Some find the elemental diet helpful under medical supervision
  • Address underlying causes with your healthcare provider

What to know about 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
