Overview
About Gluten-free bread
Gluten-free bread is made without wheat, rye or barley, and it grades clean on gluten, lactose, dairy protein, histamine, salicylates and sulfites.
What it is not is automatically low FODMAP. Gluten is the protein that gives an ordinary loaf its structure, so gluten-free bakers have to replace that structure with something, and the usual replacements are inulin, chicory root fibre, psyllium and pea or bean flour. Inulin and chicory root are concentrated fructans, which is the exact FODMAP that upsets most people who feel bloated after normal bread. That is why we grade gluten-free bread moderate on FODMAPs and fructans rather than clean. If gluten was your problem, this is a genuine fix. If fructans were your problem, swapping wheat bread for an inulin-enriched gluten-free loaf can leave you exactly where you started, or occasionally worse.

How Gluten-free bread scores
Watch for
What trips people up
- Moderate on fructans and total FODMAPs, usually from added inulin or chicory root fibre rather than from the flour itself, so a gluten-free loaf can still bloat a sensitive gut
- Clean on gluten: products carrying a certified gluten-free claim are held under 20 ppm and are appropriate for coeliac disease
- Moderate on nickel, because gluten-free blends often lean on chickpea, buckwheat, oat or teff flour, all of which sit higher in nickel than white wheat
- Read the fibre line on the label, not just the front of the packet. Loaves built on rice flour and tapioca starch behave very differently from loaves built on chicory root and pea protein
- Not paleo or AIP compliant, and only a moderate fit for DASH and Mediterranean patterns given how refined most gluten-free starch blends are

FAQ
Common questions about Gluten-free bread
Is gluten-free bread low FODMAP?
Not by default. Gluten and FODMAPs are two unrelated things: gluten is a protein, fructans are a fermentable carbohydrate, and removing one does nothing to the other. We grade gluten-free bread moderate on fructans because so many commercial loaves add inulin or chicory root fibre for texture and fibre content, and both are concentrated fructans. A gluten-free loaf built on rice flour, tapioca and psyllium is a much better low FODMAP bet than one whose ingredient list starts with chicory root.
Why do I still bloat after switching to gluten-free bread?
Because the thing that was bothering you may never have been the gluten. Wheat carries both gluten and fructans, and in people without coeliac disease the bloating and wind usually track the fructans. Switch to a gluten-free loaf that has been fortified with inulin or chicory root and you have removed the protein you were not reacting to while keeping, or increasing, the fructan load. Check the ingredient list for inulin, chicory root fibre, chicory inulin or added pulse flours.
Is gluten-free bread safe if I have coeliac disease?
Yes, when it carries a certified gluten-free claim. We grade it clean on gluten for that reason. The claim is a legal threshold rather than a marketing word, and certified products are tested to sit below 20 ppm of gluten. The gaps to watch are unlabelled bakery bread, shared toasters and shared slicing equipment, none of which the packet can protect you from.
Is gluten-free bread lower in histamine than sourdough?
Generally yes. We grade gluten-free bread clean on both histamine and histamine liberation, while sourdough sits moderate on histamine because a long wild-yeast and bacterial fermentation is exactly the condition that builds biogenic amines. If you are managing histamine intolerance, a quickly leavened gluten-free loaf is the calmer choice, and the trade is that you take on its fructan load instead.
