Yes, meat is naturally gluten-free. Plain, fresh cuts of meat, including beef, poultry (chicken, turkey, etc), rabbit, lamb and fish/seafood meat, are all gluten-free.
However, be careful with breaded or floured meats, which typically contain wheat and therefore gluten. Watch out for meats marinated or covered in sauces and broths, and be sure to read labels and check for any added ingredients. Soy and teriyaki sauces typically contain gluten, so meats marinated in these sauces are usually unsafe for those with celiac disease or non-celiac gluten sensitivity.
When purchasing hams, hot dogs or sausages, or imitation meats, choose gluten-free certified products. When it comes to deli meats, also look for certified gluten-free products and watch out for potential cross-contact sources such as slicers, knives, and nearby gluten-containing foods.
Additionally, avoid poultry and meat products that do not list the source of dextrin or starch on the product label.
