Overview
About Bread
Bread grades E for gluten, so ordinary wheat, rye and barley loaves are out with coeliac disease or gluten sensitivity.
The grade that explains more people is the quieter one: bread scores C for fructans and C for FODMAPs, and blinded trials in people who feel unwell after wheat but test negative for coeliac disease have pointed at wheat fructans, not gluten, as what actually reproduces the bloating. That distinction changes what you do about it, because gluten is all or nothing while fructans are dose dependent. If one slice is fine and two leave you distended, you are reading a FODMAP threshold rather than a gluten problem. Bread also collects a row of borderline B grades (histamine, tyramine, salicylate, nickel, free glutamate, lectin) from yeast fermentation and from being a many ingredient food, and it grades E for eosinophilic esophagitis compatibility because wheat is one of the standard foods removed in that elimination diet.

How Bread scores
Watch for
What trips people up
- Gluten graded E: standard wheat, rye and barley bread is unsafe in any amount with coeliac disease, including crumbs from a shared toaster or cutting board
- Fructans and FODMAPs graded C, so bread behaves as a dose. A single slice sits under the low FODMAP threshold for many people while two do not, which is why portion often beats total avoidance for IBS.
- High fiber and high protein loaves frequently add inulin or chicory root fiber, which is concentrated fructan. A healthier sounding bread can hit you harder than plain white.
- Yeast fermentation lifts histamine and tyramine to B, and sourdough goes further: we grade sourdough bread C for histamine and D for tyramine, so long fermentation is not automatically the gentler choice.
- Bread carries passengers that never make the product name: milk powder, honey or glucose syrup, soy flour, seeds and malted barley are all common label surprises

FAQ
Common questions about Bread
Is it the gluten or the fructans in bread that bothers me?
With coeliac disease it is gluten and the answer is strict lifelong avoidance. If coeliac disease has been ruled out and you simply feel better off wheat, fructans are the more likely culprit: a double blind crossover trial in people with self reported non coeliac gluten sensitivity found that fructans, not gluten, reproduced their bloating and pain. The practical tell is dose. A gluten reaction does not care about portion size, a fructan reaction does.
Is sourdough bread gluten free or easier to digest?
Sourdough is not gluten free. We grade it E for gluten, identical to ordinary bread, because it is still wheat. Genuinely long fermented sourdough does break down part of the wheat fructan content, which is why certain slow fermented loaves test low FODMAP, but most supermarket sourdough is proved far too quickly to earn that, and our grade for it stays at C for fructans. Fermentation also cuts the other way: sourdough grades C for histamine and D for tyramine, higher than regular bread, so it is the worse pick on a low histamine or MAOI diet.
Why does gluten free bread still upset my stomach?
Taking out the gluten does not take out the FODMAPs. We grade gluten free bread B for fructans and B for FODMAPs, better than wheat bread but not zero, and manufacturers often add inulin, chicory root fiber, apple fiber or honey to rescue the texture, all of which ferment in the colon. Read the ingredient list before concluding that gluten was never your problem.
Does toasting or freezing bread make it easier to digest?
Freezing bread and then toasting it does raise resistant starch and lower the blood sugar response, which is a genuine effect and widely reported. It does not alter the gluten and it does not remove fructans. If bread is a trigger for you, how much you eat and which loaf you buy will move the needle far more than how you store it.
