Is miso soup gluten-free?

When it comes to the question, “Is miso soup gluten-free?” the answer is maybe. The primary factor here is the soy sauce often used in miso soup. Most commercially available soy sauces contain wheat and thus, gluten. However, if the miso soup is made with gluten-free soy sauce or tamari, then the soup can be gluten-free. Therefore, always check the label or inquire about the ingredients if you’re eating out and managing a gluten-free diet.
