Soy Sauce
Most Asian dishes like sushi, noodles, or pho tend to be cooked from rice, which is almost gluten-free. However, the dipping sauce or soy sauce for these dishes contains gluten. In general, there are four main ingredients in soy sauce, including salt, wheat, soybeans, and water. During the process of fermentation, wheat proteins can be broken down and generate gluten. Though the levels are not high compared to other foods, they can still irritate people with celiac disease. Therefore, make sure to check carefully before ordering your foods. [10]
