Seaweed soup is a postpartum tonic for Korean pregnant women. Korean women drink a bowl of seaweed soup after childbirth. Because their mothers are extremely painful during childbirth, they drink seaweed soup on their children's birthdays to remember their greatness and show their respect for their mothers. Koreans believe that seaweed is good for postpartum conditioning, so there is a tradition of eating kelp. Seaweed soup is regarded as a nourishing holy product, which is cheap and nutritious. Leslie, a nutritionist from Youlian, said that kelp is rich in protein, vitamin A and minerals, which are easy to absorb and have great benefits to the body. In addition, kelp contains soluble fiber, which is easier to digest and absorb than ordinary fiber, which is helpful for smooth defecation and postpartum slimming. According to Ms. Park of New World Korea Food Store, Koreans attach great importance to diet therapy. When they see whales injured, they will look for seaweed food to heal their bodies, so they use seaweed to recuperate their bodies. According to years of experience, they believe that kelp can help pregnant women purify their blood and fight tooth loss and hair loss. Therefore, Korean women will drink seaweed soup for three months after giving birth, and then drink a bowl of seaweed soup on their birthdays to commemorate their mothers' painful childbirth. Korean seaweed soup tastes very light. There are two ways to add beef or clams. Adding beef will strengthen the body and help reduce the coldness of kelp, and adding clams will make the taste more fresh and sweet. Now only traditional Korean restaurants have this soup. They sell more kelp clam soup because it tastes fresh and sweet.
