Is it true that soba is a common hangover food?
From some experiences (not naming names), YES! Soba contains vitamins B1 and B2, several minerals, and twice the amount of proteins found in rice. Unlike noodles made of other grains, buckwheat soba also contains rutin, a bioflavonoid that helps with those suffering from arteriosclerosis and high blood pressure. Because of this, it is customary to enjoy hot soba-yu, the starchy water that soba is cooked in, added to the leftover dipping sauce to create a soup that warms the stomach and contains added nutrients lost from the cooking process.
