Key risk: Most soba noodles sold in restaurants are not 100% buckwheat. They are typically a blend of buckwheat and wheat flour (30-80% wheat). Pure buckwheat (juwari soba) is rare. Additionally, buckwheat is itself a major allergen that can cause anaphylaxis. Soba restaurants typically also serve udon in the same kitchen, creating cross-contamination risk.
