Manufacturers must list all ingredients on the ingredients list, and will name the actual grain, so will use the words ‘wheat’, ‘rye’, ‘barley’, ‘oats’; or some will use the word ‘gluten’ as well i.e. ‘wheat gluten’.

Some manufacturers also use an allergy advice box to highlight the presence of gluten in a product. This is not compulsory but also helps in selection of products on a gluten-freediet.

You should also check for statements such as ‘may contain traces of gluten’, ‘made on a line handling wheat’ or ‘made in factory also handling wheat’. This means that there is a risk of contamination.

If you are unsure about a particular product you can contact the Coeliac Society Helpline and they will go through the ingredients list with you.
