Cereal Grains
Coeliacs should not eat any food containing the following cereal grains: wheat (including spelt and kamut), barley, rye and oats. These grains contain a protein called gluten which causes an immune reaction in individuals with coeliac disease. Foods containing these grains should be avoided, as should any foods that are not specifically labelled as gluten-free.
Processed Foods
Processed foods such as breads, pastas, pastries, cakes, pizzas, and even some sauces can contain hidden sources of gluten. It is important to read all labels carefully and check for the presence of wheat, rye, barley or oats. Food manufacturers are now required to list all ingredients, so this should make it easier to identify and avoid foods containing gluten.
Cross-Contamination
Cross-contamination can also be a problem for Coeliacs. This occurs when gluten-containing foods come into contact with gluten-free foods, either during production or preparation. For this reason, it is important to avoid shared preparation surfaces and utensils, as well as foods that have been cooked in the same oil or on the same grill as gluten-containing foods.
Alcohol
Most beer and lagers contain gluten, so these should be avoided. However, there are now some gluten-free options available, such as gluten-free beer and gluten-free spirits. It is always best to check the label to make sure.
