Is millet gluten-free?
Millet is naturally gluten-free, which is one reason it suits people who avoid gluten. The thing to watch is cross-contamination during processing, not the grain itself.
Millet is naturally gluten-free. It belongs to a different plant family from wheat, barley and rye, the grains that carry gluten. Coeliac and gluten-free resources, including Coeliac UK and Beyond Celiac, list millet among the grains that do not contain gluten. The NHS names millet's relatives, like rice and maize, among the cereals that are naturally free from gluten.
Where the catch is
The grain is gluten-free, but how it is handled can change that. Millet is often grown, stored, milled and packed in places that also handle wheat. Coeliac organisations note that naturally gluten-free grains can pick up traces of gluten through this cross-contact. For most people this isn't a concern. It matters for those with coeliac disease or a real gluten sensitivity, for whom even small traces count.
Who it matters for
If you simply prefer to eat less gluten, plain millet is a naturally gluten-free choice. If you have coeliac disease, the usual guidance from coeliac bodies is to look for millet and millet flour that is labelled or certified gluten-free, rather than loose grain from open bins, so you know the processing was kept separate.
So the short answer is yes, millet itself is gluten-free. If gluten is something you need to avoid carefully, you could check the label and see whether a certified product gives you the peace of mind you want.
