Sensitivity notes

Why fodmaps food checker matters

FODMAPs are fermentable carbohydrates that can cause digestive distress in sensitive individuals. They include fructose, lactose, fructans, galactans, and polyols. These sugars are poorly absorbed in the small intestine and ferment in the colon, potentially causing bloating, gas, and discomfort.

  • Start with a 2-6 week elimination phase, removing all high-FODMAP foods
  • Keep a detailed food and symptom diary to track your reactions
  • Reintroduce one FODMAP group at a time to identify your specific triggers
  • Remember that threshold varies - you may tolerate small amounts
  • Work with a dietitian trained in the low-FODMAP diet for best results

What to know about gluten-free soy sauce

Gluten-free soy sauce, usually tamari, solves one problem and leaves another. It swaps out the wheat of regular soy sauce, so it is genuinely gluten-free and low-FODMAP. But it is still a long-fermented soy product, which makes it very high in histamine, high in tyramine and very high in free glutamate. So it is a good pick for gluten or FODMAP concerns and a poor one if your trigger is histamine, tyramine or umami/MSG-type reactions.

Watch for

  • Very high in histamine, because the long fermentation that makes soy sauce also builds histamine, a common cause of flushing, headaches and congestion after Asian meals
  • High in tyramine, which matters if you take an MAOI or get tyramine-triggered migraines
  • Very high in free glutamate, the natural umami that acts like MSG for people who react to it
  • The upside: unlike regular soy sauce, tamari is made without wheat, so it is gluten-free and low-FODMAP
