Are Oats Safe for Coeliacs on a Gluten Free Diet

{ Whether you’re craving an ANZAC biscuit or just after a bowl of oatmeal, do you know if it’s safe for coeliac’s to eat oats? Are oats gluten free and, if not… why not? We’re here to crack the code and find out if oats are safe on a strict gluten free diet. }

Words by Elysha Medhurst


Oats are a big topic of conversation when discussing coeliac disease or a gluten free diet. So the question is, are oats gluten free?

This is a tricky question because there are differing recommendations around the world. Coeliac Australia has a blanket, “no, oats are not a part of a gluten free diet” because there is no test currently available to measure gluten in oats. However, the issue is confused as the food standard codes regarding oats differ from country to country.


Coeliac Australia states the following:

The term ‘gluten’ is used to collectively describe the parts of grain storage protein (‘prolamins’) from wheat, rye, barley and oats that are toxic to people with coeliac disease. The prolamins from each grain are called something different: Wheat – Gliadin; Barley – Hordein; Rye – Secalin; Oats – Avenin. In people with coeliac disease, ingestion of these prolamins results in an immune reaction.”

The Australian food standard differs to the regulations in Europe and the USA, where oats can be marketed as ‘gluten free’. More accurately, these ‘gluten free’ oats are the equivalent of oats labelled ‘wheat free’ in Australia, i.e. there is no measurable contamination with wheat, rye or barley.”

As many coeliac sufferers would have discovered, it is possible for there to be zero physical symptoms or effects from a particular food until it has caused unknown damage. Yes, believe it or not, damage can occur even if no physical symptoms are endured.

Amongst your oats research you may have stumbled across the mention of ‘uncontaminated oats.’ Stated by Coeliac Australia, “Evidence shows that uncontaminated oats are well tolerated by most people with coeliac disease. However, in some people with coeliac disease, oat consumption can trigger a potentially harmful immune response.”

An article by the Celiac Disease Foundation states that one in 12 CD patients had activated avenin-specific T cells, or an immunological response, whilst ingesting 100 grams of uncontaminated oats per day in a three-day clinical trial. Although the risk of damage via an autoimmune response is fairly low across those who have coeliac disease, the risk is one Coeliac Australia is not willing to take.

Therefore, it’s not a surprise that the Australian Food Standards Code does not allow products containing oats to have their packaging labelled with ‘gluten free.’

It is recommended by the Coeliac Disease Foundation that if you are willing to try uncontaminated oats as a Coeliac that you do so under the supervision of your physician. So in other words don’t try this at home without permission. However, it should be reiterated that the foundation also stresses that oats are not a part of nor encouraged to be eaten when undergoing a gluten free diet.

We choose to follow the recommendations by Coeliac Australia and stay away from oats. Yes, even oats that state gluten free and/or non-contaminated that are currently on the market. Although tested oats are considered gluten free in other countries, they may not pass the same test in Australia. Australia has the most stringent gluten free product standard in the world. Australia’s test for gluten free is a maximum of 3 parts per million, making the gluten content non-detectable. In the United States and United Kingdom, the legal limit is up to 20 parts per million. With so many unknowns around this topic, our number one priority is staying healthy and safe when choosing where and what to eat.
