- People with coeliac disease can safely eat many common plants, seeds, grains, cereals and flour, including corn, polenta, potatoes, rice and soya.
- However they should avoid barley, wheat, rye, couscous and semolina as they contain gluten.
Gluten is a protein found in the cereals wheat, rye and barley. Cereals are the edible seeds or grains of the grass family and provide us with:
- carbohydrate – a source of energy
- fibre – which slows digestion and absorption of nutrients from the gut and helps prevent constipation
- most B vitamins, especially thiamin, riboflavin and niacin – needed for a number of processes in the body including helping the body get energy from food and to maintain healthy skin and vision.
Here's a guide to common plants, seeds, grains, cereals and flours. You can also download a fact sheet on this from the right hand side of this page.
Not gluten free
- Barley (including products that contain malted barley such as malted drinks, beers, ales, lagers and stouts)
- Bulgar wheat
- Durum wheat
- Emmer (also known as faro)
- Khorasan wheat (commercially known as Kamut®)

Need to check
- Barley malt extract (some breakfast cereals containing barley malt extract are suitable)
- Cassava (manioc)
- Gram flour (besan)
- Pulses (peas, beans, lentils)
- Urd/urid/urad flour.
Although some flours are naturally gluten free, they can be milled where wheat flour is also milled. See our Food and Drink Information for suitable products and always look for flours labelled gluten free.
Contamination occurs either because wheat flour is in the atmosphere or traces of it remain in storage containers. It’s possible that flours made from pulses, such as gram and urad flour, may be contaminated although they are naturally gluten free.
Find out about reading food labels which may help in deciding whether products are safe for you.
Oats can be eaten by most people with coeliac disease but only if they're marked 'gluten free'. Uncontaminated gluten free oat products are listed in the Oats chapter of our Food and Drink Information.
