Soba noodles are noodles made from buckwheat.
Buckwheat is a gluten-free grain that contains no wheat. Soba noodles, because of their buckwheat content, are a slow-releasing carbohydrate. They contain selenium and zinc.
Soba noodles are eaten as part of the Okinawa diet and by most health-conscious Japanese.
Soba noodles and buckwheat pasta are both available from good health food stores.
