What the sources tell us

The Celiac Disease Foundation includes nut flours in its list of grains, legumes, seeds and other starchy foods that are naturally gluten-free. The Gluten Intolerance Group's guide for people starting a gluten-free diet also lists nut flours among the naturally gluten-free grains and flours to choose, next to bean flours, rice, corn and sorghum.[2][3]

NIDDK, part of the National Institutes of Health, says that flour made from gluten-free foods such as nuts, rice, corn, buckwheat or beans is safe to eat.[1]

In its article on gluten-free grains and flours, the Gluten Intolerance Group names almond as one of its favorite nut flours, along with hazelnut and walnut. It says nut flours are traditionally used in dessert tortes, give moist baked goods and provide a significant amount of protein.[4]

The same article notes that nuts are high in fat, so it suggests keeping nut flours in the refrigerator or freezer so they do not go rancid too quickly. It also says you can grind your own nut flour in a coffee grinder or food processor, as long as you stop before it turns into nut butter.[4]

Other Gluten Intolerance Group articles list almond flour among the ingredients used for gluten-free bread, together with rice flour, sorghum, bean flour and tapioca starch, and mention pasta made primarily from almond flour.[6][5]

The Celiac Disease Foundation adds a caution about naturally gluten-free grains in general. Some research indicates that some of them may contain gluten from cross-contact during harvesting and processing, so it suggests buying only versions tested to contain less than 20 parts per million of gluten if you are concerned, and it does not recommend buying grains from bulk bins.[2]
