Being a Fussy Foodie/ Gluten Free

Are oats gluten free?

A question I am often asked is are oats gluten free? Well the not-so-straightforward answer is it depends!
Confused? Hopefully you won’t be after you have read this simple summary.

So are oats gluten free? Firstly, we need to clarify whether you have Coeliac Disease (i.e. a true allergy to gluten) or if you are gluten intolerant (i.e. you avoid wheat, rye and barley products for symptom relief of problems such as bloating, diarrhoea, etc.)  

Coeliac Disease

It is thought that completely pure, uncontaminated oats would be unlikely to trigger a reaction for most people with Coeliac Disease BUT (and this is a big but) during processing most oats and oat products on the market will be contaminated with gluten from wheat, rye or barley. The amount may be tiny but for someone with an allergy (which Coeliac Disease is) even a minute amount of gluten can cause bowel damage  and increased risk of health problems, even if symptoms are not obvious.

VERDICT:  Avoid oats unless advised otherwise by a doctor / specialist

Gluten Intolerance

If you don’t tolerate gluten in the diet but you do not have coeliac disease oats should be absolutely fine to include in your diet and can actually help with irritable bowel symptoms. Oats contain soluble fibre, which helps to soften stools and may ease bowel symptoms, whereas insoluble fibre (e.g bran, wheat) can be an irritant for some people.

VERDICT:  Oats are beneficial and should be included in the diet

I hope this answers the question of are oats gluten free?

    Just after I wrote this article someone enquired about whether oat milk is suitable for those on a gluten free diet. So I checked out the Oatly website – and I’m still not sure!! Here’s what they say…

    “Only top-quality oats are used. You’ll find as little as 6 other types of grain per 30 000 oats. However, we do recommend that you consult your doctor first”.

    It is generally accepted Coeliacs can only take 2 parts per million of gluten, hence if ‘6 other types of grain per 30000 oats’ are present then no oat milk is not gluten free.

    Until I was diagnosed with coeliac disease, I was not truly aware of the amount of contaminants, bulking-out, and – put simply – adulteration that modern food suppliers give us. It is nothing short of a scandal. You soon learn the lessons about “pure food” – but you also learn quickly that, although most supermarkets advertise the availability of pure food (like GF oats) individual stores in a chain (such as Tesco, Asda) often decide not to stock such products. Following a coeliac diet (especially when also diabetic) is a real struggle for product availability.

    Just FYI, Celiac disease is an autoimmune disorder, not an allergy

    Thank goodness – I can actually try having porridge for breakfast [which I love]. I’m not a bread eater but because I’ve just been diagnosed with coeliac disease, thought I’d bake some because I was sick of just having a banana for breakfast. What a disaster [3 times – I’m a slow learner!]. I thought I couldn’t eat oats but I’m going to give it a try.
    A huge thank you.

    The unanswered question, are oats gluten free? It’s not useful to ask about tolerance levels if you are looking for said answer for your own interests.

    Whilst not exactly the same as gluten on a molecular lever, oats contain avenin. Avenin behaves like gluten and can cause similar effects in the gut as gluten.

    If oats feel like they have gluten in, and maybe cause side effects related with gluten, I’m led to believe it’s the avenin.

      Hi I have this rash it gets very bad if you have wheat I seen my doctor and he’s gave me tablets DAPSONE.He said that I am one in a hundred to have this and they work but if I forget to take them they come back with a vengeance doctor said I’ll be on these for 6 year and I have to have blood tests too it’s starts with a test once 1 week then every 2 week then it go’s to once a month. Just to see if the tablets are ok for your body as these are for people who have leprosy hope this has helped you in anyway
