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

Ingredient notes

What to know about xanthan gum

Xanthan gum is one of the genuinely quiet additives. Our data grades it low FODMAP and clean on gluten, lactose, dairy protein, sulfites, nitrites and nightshades, with a scattering of borderline marks and one real caveat: it is a fermentable fibre, and it is graded borderline for SIBO. It is not a plant extract. The bacterium Xanthomonas campestris is fed sugar in a tank, secretes a long-chain polysaccharide, and that slime is precipitated, dried and milled. A fraction of a percent by weight turns a batter into something that behaves like it has gluten, which is why gluten-free bread exists in its current form. The two things worth knowing are what sugar it was fed on, and how much of it you are actually eating.

Watch for

Graded borderline for SIBO fermentation.Xanthan gum is a soluble fibre, so the quarter teaspoon in a loaf is a non-event while a heaped tablespoon stirred into a smoothie can produce real gas, bloating and looseness.
The fermentation substrate never appears on the label.Corn is the most common feedstock, but wheat, soy and dairy sugars are all used commercially, and people with severe corn, soy or wheat allergy sometimes need to ask the manufacturer directly.
Certified gluten-free products use a non-wheat substrate and processing removes protein residues, but plain bulk xanthan gum sold without a gluten-free claim is worth verifying if you have coeliac disease.
Xanthan gum thickeners are not for premature infants.The FDA warned in 2011 after cases of necrotising enterocolitis in preterm babies given a xanthan gum based feed thickener.
Graded low FODMAP with no gluten, lactose or dairy protein.If a gluten-free baked good upset you, the flour blend (often chickpea, lupin, inulin or sorghum) is a far more likely culprit than the gum holding it together.
