How to Read a European Gluten-Free Food Label

A European food label is more honest than it looks, once you know which words are doing legal work and which are just marketing. The good news for anyone shopping gluten-free in the EU or UK is that the two most important terms — gluten-free and the list of bold allergens — are defined in law, not left to the manufacturer’s goodwill. The confusion comes from the words around them. Here is how to read the whole thing.

“Gluten-free” is a regulated claim — and a low number

In the EU and UK, a product may only say gluten-free if it contains no more than 20 mg/kg (20 ppm) of gluten. That threshold is set by Implementing Regulation (EU) No 828/2014 and it is the same limit recognised internationally by the Codex standard. It is not a vague reassurance; it is a measured ceiling the manufacturer must be able to stand behind.

You may also see “very low gluten”, a separate legal category allowing 21–100 ppm, used mainly for some wheat-starch-based products. For most people with coeliac disease the everyday choice is the gluten-free tier at ≤20 ppm. When a product carries that claim, it is suitable for a gluten-free diet — the number is the point.

The bold allergens are your fastest scan

Regulation (EU) No 1169/2011 requires the 14 major allergens to be emphasised in the ingredients list — usually bold, sometimes capitals or a different colour. Four of the fourteen are the gluten-containing cereals: wheat, barley, rye and oats (plus their hybrids like spelt and kamut, which appear as “wheat”).

This is the single most useful habit: don’t hunt the whole label, scan the bold words. If none of the four cereals appears in bold, the product contains no declared gluten source. If one does, it’s in there and named — the law makes hiding it non-compliant.

The crossed-grain symbol is a bonus, not the law

The crossed-grain symbol — an ear of wheat inside a circle, often with a code — is a private certification mark licensed by national coeliac societies and the European umbrella body AOECS. It signals independent verification against their standard, which is a genuinely stronger assurance than the printed words alone. But its absence means nothing: plenty of compliant gluten-free products never pay to carry it. Treat the symbol as a helpful extra, not a requirement.

“May contain” is voluntary — and not an instruction to avoid

This is where most people over-restrict. Precautionary allergen labelling — “may contain traces of gluten”, “made in a factory that also handles wheat” — is voluntary. It is not harmonised across the EU, there is no legal threshold behind it, and it is not an automatic red light. A manufacturer may add it out of genuine cross-contact risk, or simply out of caution and liability, and the label gives you no way to tell which.

That means “may contain” is a judgement call, not a rule. A product can legally carry a valid gluten-free claim — a measured ≤20 ppm — and a precautionary “may contain” line at the same time, because the two statements answer different questions. Reading every “may contain” as disqualifying rules out a large part of the accessible shelf for no regulated reason. Weigh it against your own sensitivity rather than treating it as a stop sign.

The ingredients that sound alarming but are exempt

Some wheat-derived ingredients are so heavily processed that the gluten is gone, and EU law reflects this. Annex II of Regulation (EU) No 1169/2011 exempts the following from allergen declaration entirely, on the basis of EFSA assessments that they are unlikely to cause a reaction in people with coeliac disease:

• Wheat-based glucose syrups (including dextrose)
• Wheat-based maltodextrins
• Glucose syrups made from barley

So maltodextrin, despite the “malt” in its name, is not a hidden gluten source — even when it’s wheat-derived. The same goes for glucose syrup and dextrose. You can stop scanning for these.

A couple more that trip people up:

• E-numbers do not indicate gluten. They’re additives identified by a code; the code tells you nothing about a cereal source. If an additive were derived from a gluten cereal in a way that mattered, the cereal would have to be declared.
• “Wheat-free” is not the same as gluten-free. A wheat-free product can still contain barley or rye. Only the regulated gluten-free claim covers all the gluten cereals at once.
• Barley malt extract — common in cereals and some sauces — is a gluten source and must be declared. This is the one that’s genuinely worth watching, not maltodextrin.

A word on oats

Oats are naturally free of wheat gluten, but standard oats are routinely cross-contaminated during growing and milling. Only oats specially produced as certified gluten-free oats meet the ≤20 ppm standard. Most people with coeliac disease tolerate certified gluten-free oats well, but a minority react to avenin, an oat protein — so introduce them cautiously and watch your own response. On a label, look for oats named specifically as gluten-free, not just “oats”.

Your thirty-second label routine

• Look for the regulated gluten-free claim (≤20 ppm). If it’s there, that’s the strongest single signal.
• Scan the bold allergens for wheat, barley, rye, oats.
• Treat “may contain” as voluntary information to weigh, not an automatic no.
• Ignore maltodextrin, glucose syrup, dextrose and E-numbers as gluten worries; do watch barley malt extract and wheat flour used as a thickener or bulking agent.
• Remember wheat-free ≠ gluten-free, and that the crossed-grain symbol is a welcome extra rather than a legal must.

This is educational, not medical or legal advice, and labelling rules can change — if you spot something here that no longer matches a current label, tell us and we’ll re-check. Outside the EU and UK the terms differ, which is a subject for its own guide.
