Coeliac disease, and the words on a label that are gluten

Coeliac disease is the one condition Munchable checks where the answer is not a matter of degree. A gluten grain is a gluten grain wherever it appears on the list, so there is no dose grading here. What is uncertain is the label, not the science.

Why this rule set works differently

Every other condition Munchable checks is about amount. A trace of onion and a bulb of it are different questions for someone with IBS, so the engine reads where an ingredient sits on the label and grades accordingly. Coeliac disease is not like that. The legal threshold for a gluten-free claim is 20 milligrams per kilogram, which is a quantity you cannot see on an ingredients list, so wheat flour ninth on the list is flagged exactly as firmly as wheat flour first.

That makes the interesting work the vocabulary rather than the arithmetic. Gluten hides behind words that do not contain the word gluten: semolina, couscous, bulgur, spelt, kamut, farro, seitan, rusk, panko, malt extract, malt vinegar. Munchable keeps one curated list of those words, shared with the gluten allergen check, so the two halves of the app can never disagree about what a grain is.

Oats, and the words that do not say

Oats do not contain gluten, and they are listed with the gluten cereals in EU and UK law anyway, because they are grown, milled and transported alongside wheat. Pure oats are a separate supply chain and a pack that has paid for it says so. So Munchable treats plain oats as a caution rather than an avoid, and clears them when the pack claims gluten free. Oat milk, oatmeal, oat bran and muesli are read the same way.

A second group of words gets the same treatment for a different reason: they name a form of food rather than the grain it was made from. A tortilla is corn or wheat. Soba is buckwheat, often cut with wheat flour. Brewer’s yeast is a barley by-product, while yeast extract is not and stays quiet. In each case the honest answer is that the label has not said, and a caution says that where an avoid would be guessing.

What the pack says about itself

Reading ingredients alone gets coeliac disease badly wrong in one direction. Certified gluten-free bread is made with specially processed wheat starch, gluten-free beer is brewed from barley, and gluten-free oats are oats. All three read as an avoid from the ingredients alone, and all three are exactly what a coeliac shopper is looking for. So Munchable reads the gluten-free claim off the pack and attributes it to the manufacturer, because it is their legally defined statement and not Munchable’s.

Where a claim and an ingredient genuinely disagree, the product is held at a caution rather than cleared or condemned. One of the two readings is wrong and the packet in your hand is the only thing that can settle it.

What Munchable will not say

Munchable never reports a product as gluten free. Every coeliac verdict carries a line saying so. A good fit here means nothing on the listed ingredients is a gluten grain, which is a different sentence: it cannot see a shared production line, a recipe change since the data was captured, or the half of the pack that was not photographed.

For the same reason the gluten allergen check is a separate layer that runs alongside this one and is deliberately less forgiving. It warns on oats and on certified gluten-free oats, because an allergen warning only ever adds caution, and over-warning is the error that layer prefers to make.

What Munchable reads off the label

  • Wheat and every name for it: semolina, couscous, bulgur, durum, spelt, kamut, einkorn, emmer, farro, seitan
  • Barley and rye, including malt, malt extract, malt flavouring and malt vinegar
  • Wheat starch, wheat protein and wheat bran, which the taxonomy files away from the grain
  • Bread, breadcrumbs, rusk, panko, pasta, noodles, dough, pastry, biscuits, cake, wafers, pretzels and beer
  • Oats, oat milk and muesli as a caution, cleared by a gluten-free claim
  • The words that name a form rather than a grain: tortilla, soba, brewer’s yeast
  • The pack’s own gluten-free claim, attributed to the manufacturer
  • The printed "Contains" and "may contain" lines, read independently of the ingredients
  • Rice, maize, buckwheat, quinoa, millet, sorghum, teff and polenta left alone, along with the wheat glucose syrups that EU law exempts

How certain is this?

Gluten avoidance for coeliac disease is not a matter of degree, so there is no dose grading here. What is uncertain is the label, not the science: a word that names a form of food rather than a grain is cautioned rather than cleared.

The rule set behind this page is versioned (0.1.0-draft) and cites its basis: Regulation (EC) 41/2009 and (EU) 828/2014: the 20 mg/kg gluten-free claim; EU Regulation 1169/2011 Annex II: cereals containing gluten, and the wheat glucose syrup exemptions; Coeliac UK food and drink guidance (oats as a separate supply chain). Every verdict is produced by those fixed rules, never by a language model.

Ingredients Munchable flags for this

Each one has its own page with the answer at the top, because the amount and the position on the label decide how much it matters.

Questions

Does a good fit mean the product is gluten free?

No, and Munchable says so on every coeliac verdict. It means nothing on the listed ingredients is a gluten grain. It cannot see a shared production line, a recipe change since the data was captured, or a part of the pack that was not read.

Why are oats a caution rather than an avoid?

Oats do not contain gluten but are routinely contaminated with wheat in growing and milling, which is why EU and UK law lists them with the gluten cereals. Uncontaminated oats are a separate supply chain and a pack that uses them says gluten free, so Munchable cautions on plain oats and clears them when the claim is there.

Why is wheat glucose syrup not flagged?

Because the processing removes the gluten, which is why Annex II of the EU food information rules exempts wheat-based glucose syrups, dextrose and maltodextrin from allergen declaration. Flagging them would put an avoid on a great deal of ordinary confectionery for no benefit.

Should I use this instead of a gluten-free certification?

No. A certification scheme audits a production line and Munchable reads a label. Use it to narrow down what to pick up and read, not to replace the claim on the pack.

Is coeliac disease the same as the gluten allergen setting?

They answer the same question from the same curated list of grains, and they do different things with it. The condition grades what it finds and explains it; the allergen layer only ever adds a warning and never clears anything. Turning on coeliac disease switches on the gluten allergen too, so you get both.

The bit we have to say

Munchable is a wellness tool, not medical advice. It does not diagnose or treat anything and is not a substitute for your doctor or dietitian. It warns about the allergies you list when the product data names them, but it never tells you a product is free from one, so always read the physical label.
