Soba is the Japanese name for buckwheat. It usually refers to thin noodles made from buckwheat flour, or a combination of buckwheat and wheat flours (Nagano soba).Soba is a good nutritional addition to a diet reliant on white rice and wheat flour. Thiamine, missing from white rice, is present in soba; eating thiamine (vitamin B1) can help prevent the disease beriberi. Soba contains all eight essential amino acids, including lysine, which is lacking in wheat flour. The tradition of eating soba arose in the Edo period
