There are many naturally gluten-free grains that you can enjoy in a variety of creative ways. Many of these grains can be found in your local grocery store, but some of the lesser-known grains may only be found in specialty or health food stores. It is not recommended to purchase grains from bulk bins because of the possibility for cross-contact with gluten.
The following grains and other starch-containing foods are naturally gluten-free:
Rice
Cassava
Corn (maize)
Soy
Potato
Tapioca
Beans
Sorghum
Quinoa
Millet
Buckwheat groats (also known as kasha)
Arrowroot
Amaranth
Teff
Flax
Chia
Yucca
Gluten-free oats
Nut flours
There has been some research that some naturally gluten-free grains may contain gluten from cross-contact with gluten-containing grains through harvesting and processing. If you are concerned about the safety of a grain, purchase only versions that are tested for the presence of gluten and contain less than 20 ppm.
