Gluten allergy foods to avoid

Gluten is found in wheat, barley and rye, so common foods such as bread, pasta, cakes, biscuits and many breakfast cereals may cause symptoms when one of these grains is the trigger. It can also appear in sauces, soups, processed meats, seasoning mixes and malt-flavoured products. Cross-contact can happen when gluten-free food shares a toaster, chopping board, fryer or spread with ordinary food.

A reaction to gluten-containing food may be an allergy, coeliac disease or another intolerance; these are different problems and need different advice. A food allergy can include itchy mouth or throat, hives, vomiting, wheezing or swelling. An itchy throat can have several causes, so the symptom alone cannot identify the food responsible.

Read the full ingredient list each time, including on familiar products, and look for wheat, barley, rye, malt and ingredients that name a gluten-containing grain. Choose naturally gluten-free foods such as rice, potatoes, vegetables, fruit, eggs, meat and fish when they suit your needs. Ask restaurants about shared cooking surfaces and utensils, and keep a written record of what you ate and when symptoms appeared.

Arrange an assessment with a clinician or allergy service before making a long-term restrictive diet. Allergy Testing may help investigate an immediate food reaction, while a clinician can decide whether another evaluation is needed. Do not test a suspected food at home if a previous reaction involved breathing trouble or swelling.

Seek emergency help immediately for trouble breathing, throat or tongue swelling, faintness, confusion, repeated vomiting, or rapidly spreading hives after eating. These can be signs of anaphylaxis. If you have a prescribed adrenaline device, use it as instructed and call emergency services; do not wait to see whether symptoms settle.

Ask which foods and ingredients you should avoid, whether you need an emergency action plan, how to prevent cross-contact, and whether you should see an allergy specialist or dietitian. Clarify what to do if a label is unclear and whether family members or school staff need written instructions.
