Like "For things like celiac disease, gluten is kind of a bucket and may not actually mean gluten. There are a few different proteins that cause issues for people with the disease and there are a lot of grains that don't contain any of them or only one which may or may not cause issues for people. Generally rice, quinoa, buckwheat and possibly oats and rye depending on the person are safe to eat. Rice is probably the biggest and easiest one to use but quinoa is getting pretty big."
