Buckwheat noodles is one of the most nourishing fast foods on earth. Buckwheat - a plant high in protein and fiber, also has high levels of minerals such as magnesium. Since buckwheat is not a type of wheat but instead a seed of a broad leaf plant related to the rhubarb family, it is ideal for gluten free and wheat free diets. All King Soba noodles are carefully sourced and certified according to organic standards, and processed in a dedicated wheat-free factory where no grains containing gluten are processed or allowed. USDA regulated, King Soba foods meet the Codex Alimentarius Standards for Gluten Free Foods and are regularly tested by an independent, third party in the United States. No fillers, nothing artificial, just 100% organic buckwheat. Please note; the factory may handle nuts and sesame products.
