Gluten-free and Grain-free usually go hand-in-hand. But there are many grains that are gluten free and safe for people with Celiac Disease or gluten intolerance due to other medical conditions.
Below you will find a full list of grains and a short explanation about whether they are gluten free, why they are or are not, and any other important information. For grains that require more details, I will link to another article that goes deeper into the topic. If you would like a full list of products with gluten free ratings but without any explanation, click here.
There are five different categories I have split the ratings into:
Gluten Free. These products are naturally gluten free and usually have little to no chance of cross-contamination. You can consume these products without much concern. Always look for gluten free labels as well as may contain statements.
Naturally Gluten Free. For this category, these products are naturally gluten free, but you should read labels carefully and be cautious as always when deciding whether to purchase and use a product for those who need to be strictly gluten free.
Gluten Free Label Required. These are products that are naturally gluten free or usually gluten free, but the potential risk that they may contain gluten is high enough that you shouldn’t purchase this product or a product with this as an ingredient unless there is a gluten free label on the product.
Usually Gluten Unless Marked. The products marked with this rating are usually made with gluten-containing products, however, there are gluten free alternatives on the market. These products will be specifically marked gluten free if they are safe, typically the gluten free label will be part of the product name or found prominently on the package.
Never Gluten Free. These are the items with a full-sized stop sign on them. These products are not gluten free and are never safe for someone with Celiac Disease or who otherwise requires a gluten free diet. Look for these as a warning sign on labels.
This list of grains is done alphabetically. When I’ve written an article that provides a more in-depth response, I have provided the link just following the short explanation. If you prefer the lists in graphic form, scroll to the bottom of the page to find the lists separated into gluten free and gluten grains.
