What is gluten?
Gluten is a protein found in most wheat products, and acts as the “glue” that helps to hold wheat, barley, kamut, spelt, farro, durum, bulgur, rye, and semolina together to maintain their shape.
Gluten is naturally occurring, yet many people have a hard time digesting it as well as having immune responses to it when it enters their system. Many people who experience side effects from eating gluten have either celiac disease or a food intolerance, and choose to avoid gluten entirely in their diets.

Sweet potatoes may not be gluten-free if ingredients with gluten have been introduced to them.
Sweet potatoes contain no gluten themselves, so if there was gluten in a dish, it would likely be from a seasoning or other ingredient that was added to a recipe making it unsafe for us gluten-free folks.
If sweet potatoes have been seasoned with spices or seasoning packets from the store, they may not be gluten-free as gluten is often present in these premade packets and seasoning blends.
If sweet potatoes have been added to a soup or a sauce, they might not be gluten-free. Sometimes flour is added to soups and sauces to thicken them, and this might be a place where gluten gets incorporated into a naturally gluten-free dish making it unsafe for folks following a gluten-free diet.
Especially if you’re buying a packaged food with sweet potatoes, do your due diligence in looking at ingredients lists before purchasing to find hidden gluten ingredients.
