Buckwheat is another gluten-free grain alternative that has become very popular. Buckwheat may have "wheat" in its name, but this gluten-free replacement is actually related to rhubarb and other similar plants and not wheat. While quinoa can be used to make a variety of traditionally wheat type foods, such as breads, noodles and pancakes, buckwheat has enjoyed much more success in this regards as gluten-free buckwheat is often the foundation of gluten-free breads, noodles and other dishes. For example, buckwheat noodles are extremely popular in Japan.
