Are they safe to eat?
There is a difference of opinion as to whether certified gluten free oats are really safe for coeliac sufferers to eat.
I can say that I have tried them, and suffered no ill effects, even though I am very sensitive.
It may be worth asking your doctor or dietician for advice as to whether to include them in your diet if you are gluten intolerant.
Here in the UK, if you direct the question - are oats gluten-free - to the Coeliac Society, they will err on the side of caution, but it really is a personal choice.
You might like to remember the saying "when in doubt, do without" before making your decision.
If you're not happy eating them there are alternatives. You can make porridge, for example, from millet flakes, or buckwheat. These, along with Rice flakes, can also be used in muesli mixes.
I have included some recipes on this site where you can use either oats or millet flakes.
