The Australian and New Zealand rule
Coeliac Australia’s April 2026 update confirms that products containing oats cannot be labelled gluten-free in Australia or New Zealand [1]. FSANZ likewise states that gluten-free claims cannot be made on foods containing oats or oat products [2].
That is a commercial labelling rule, but it also highlights how poorly a global recipe can assume that “gluten-free oats” means the same thing everywhere.

The United States is different
FDA rules allow oats to appear in food labelled gluten-free when the product otherwise satisfies the rule, including keeping unavoidable gluten below 20 ppm [3]. Other overseas regimes also recognise qualifying oats.
The cookbook does not choose the most permissive rule simply because it would allow more breakfast recipes. Global formulation can be stricter than one market’s label threshold.

Tolerance is also individual
Coeliac Australia reports that many people with coeliac disease tolerate pure, uncontaminated oats, but that up to 10% may react - from symptoms through to rare villous atrophy - and it encourages individual discussion with the medical team before oats are introduced [1].
That is precisely why a general cookbook is the wrong place to make a reader perform an oat challenge. The evidence Guide can explain the choice; the recipe remains oat-free.

What exclusion does and does not mean
The oat-free rule is a conservative recipe-design decision for a globally usable product. It is not a claim that oats are biologically identical to wheat, rye or barley, or that no person with coeliac disease can ever tolerate pure oats.
Where oats would normally supply fibre or texture, recipe development should use other genuinely suitable ingredients rather than relying on a footnote that pushes the eligibility decision back onto the reader.
