Three different claims wearing one phrase
The words free from, and their variants, do very different regulatory work depending on what follows them. Failing to separate the cases is the source of most confusion in this area.
Gluten. Statements about gluten content are subject to specific rules with defined thresholds. Gluten-free is a controlled description, and there is a further defined term for very low gluten. This is the most tightly specified case.
Nutrients. Absence claims about nutrients, such as sugar-free, fat-free or salt-free, are nutrition claims. They may only be used when the specified conditions for that claim are met, and the conditions are numerical.
Other ingredients and allergens. Statements that a product is free from an allergen other than gluten, or free from a category of ingredient, are not on a defined list. They rest on the general requirement that food information must not mislead, backed by whatever controls and verification the business has in place.
Why gluten is different
Gluten-free is defined because it needed to be. The description is used by people managing a condition where the relevant quantities are extremely small, and a claim without a threshold would have been unusable.
The rules therefore fix a maximum gluten content for a food described as gluten-free, and a separate, higher, threshold for the very low gluten description. Both are numerical and both are testable analytically.
That is the whole reason the term is reliable in a way that other free from wording is not. It has a number behind it, an analytical method, and a legal consequence for exceeding it. What it does not do, and cannot do, is tell any individual whether a food is appropriate for them. That is a clinical question and belongs with a GP, a specialist or a registered dietitian.
| Claim | Mechanism | Checkable from the pack |
|---|---|---|
| Gluten-free | Defined legal threshold | Not directly, but the threshold is public and enforceable |
| Very low gluten | Defined legal threshold, higher than gluten-free | As above |
| Sugar-free, fat-free, salt-free | Nutrition claim with a numerical condition | Yes, against the nutrition declaration |
| Free from a named allergen other than gluten | General misleading rule plus business controls | No |
| Free from an additive category | General misleading rule plus the ingredients list | Yes, by reading the list |
| Free from something the category never contains | Rules on claims implying special characteristics | Yes, by looking at comparable products |
Structure set out by this newsroom from the published rules named in the sources below. It is not a survey, a measurement or a market study.
Nutrient absence claims
Sugar-free, fat-free, salt-free and their relatives sit inside the nutrition claims list, and each has a defined condition expressed per 100g or per 100ml. A product may use the claim only if it meets the condition, and only in a form of wording with the same meaning as the permitted claim.
Two implications follow. First, these claims are checkable directly against the nutrition declaration on the same pack, which is a rare piece of internal consistency. Second, they are not statements that the product contains none of the nutrient in an absolute sense. The condition is a threshold, and thresholds are not zeroes.
There is also a category of related claims about reduction rather than absence, which carry their own conditions, typically requiring a defined difference from a comparable product. Where a comparison is being made, the comparator matters, and the claim rules address how it must be identified.
Allergen absence claims outside gluten
This is the largest and least standardised group. A statement that a product is free from a named allergen other than gluten has no prescribed threshold in law and no prescribed verification method.
What sits behind such a claim in practice is a business's allergen management: separated production, cleaning regimes, supplier specifications, analytical testing where a suitable method exists, and documentation of all of it. A serious claim rests on a serious system. The pack itself cannot show you which you are looking at.
This creates a genuine asymmetry with precautionary wording. A may contain statement is voluntary and unstandardised, and so is a free from statement about the same allergen. Both describe the same underlying reality of shared equipment and supply chains, from opposite directions, and neither is anchored to a number.
For an individual managing an allergy, what to do with that is not a labelling question. It is a clinical one, and this publication will not answer it. The NHS and an allergy specialist are the right sources.
Free from as positioning
There is a fourth use of the phrase which is neither a legal threshold nor an allergen assurance, and it is now very common: free from an ingredient category that the product was never likely to contain, or that carries a negative association in current marketing.
The rules that apply here are worth knowing. A nutrition claim may not be made if it is misleading, and there are provisions dealing with claims that imply a food has special characteristics when all similar foods share them. Advertising rules address the same territory, since implying that a product is distinctive on a dimension where it is not is capable of misleading.
The reading habit for a shopper is straightforward. Ask whether comparable products would also qualify for the claim. Where the answer is that essentially all of them would, the claim is describing a category rather than a product.
Putting it together
Free from wording should be read by first identifying which of the four situations applies. A defined threshold, a nutrition claim condition, a business assurance, or a category characteristic presented as a product feature. The phrase looks identical in all four cases and means something entirely different in each.
Only the first two can be checked from the pack itself. The third depends on systems you cannot see. The fourth can be tested by looking at the shelf around the product.
Where this stops
Nothing here tells you whether a food is suitable for you, and it is not intended to. Free from claims intersect directly with medical circumstances, and this publication does not give clinical or dietary advice of any kind. For allergy, intolerance, coeliac disease or any dietary question tied to health, speak to your GP or a registered dietitian, and start with the NHS.
