Is Pad Thai gluten-free?

Maybe, it depends on if the ingredients used in preparing Pad Thai are gluten-free or not. Generally, Pad Thai uses rice noodles, which are naturally gluten-free. However, the sauces, particularly the soy sauce can contain gluten. Always make sure to ask for a gluten-free soy sauce or ensure that all the ingredients are gluten-free if you are preparing it at home.
