What You Need to Know
Udon is a type of Japanese noodle made primarily from wheat flour, which contains gluten. Gluten is a protein found in wheat and related grains, making Udon unsuitable for individuals with gluten sensitivities or celiac disease. The inclusion of wheat flour in its ingredients means that it cannot be classified as gluten free, posing a risk for those who must avoid gluten in their diet.
For those following a gluten free diet, it is essential to seek out alternative noodle options that are specifically labeled gluten free. Many brands offer gluten free noodles made from rice, buckwheat, or other gluten free grains. Always check ingredient labels carefully to ensure the product meets gluten free standards and avoid cross-contamination.
