Are there certified gluten-free beans and other grains?

Melinda Dennis MS, RDN, LDN
I am concerned regarding beans and other grains being contaminated with gluten-containing grains. How can I be secure that I won't get glutened? Are there any certified gf grains, either dried or canned? Do I need to worry about quinoa, teff, ground cornmeal, etc.? I miss having these powerhouses in my diet but I am scared to death of being glutened. The last episode landed me in ER so I need to be sure.


Gluten free grains, such as quinoa, teff, amaranth, etc., are a healthy addition to a gluten-free diet because they are high in fiber, protein, vitamins and minerals. It is very important to choose gluten free grains labeled gluten-free since these grains easily can have had cross contact with gluten-containing grains such as wheat, rye and barley.1

Dried and canned beans and legumes (lentils, split peas, and chick peas) are also nutritional powerhouses. More recently we have been able to find labeled gluten free canned and dried beans, (kidney, black, pinto, etc.) and legumes in the grocery stores and online. To prevent cross contact, do not purchase grains or beans, etc., from bulk bins. Purchase them in sealed packages labeled gluten-free. “Under GIPSA standards (Grain Inspection, Packers & Stockyards Administration), lentils are allowed to contain a certain percentage of foreign grain, including wheat, barley, and rye.”2 So, whether you choose labeled or certified gluten-free dried beans, peas and legumes or not, it’s a good idea to spread them out on a cookie sheet and look for random grains of wheat, rye and barley.2 Rinse and drain them carefully. Rinse and drain canned ones, as well.

Check out for more information on foreign grains found in lentil packages (both certified packages and those labeled “naturally gluten-free food”).
