1, Kelp soup not only supplements iodine, but also reduces weight! Chinese people have been eating kelp for more than a thousand years. In the book "Compendium of Materia Medica" written by Li Shizhen, the famous doctor in Ming Dynasty, it is recorded that kelp can "mainly treat hot air and nodules". Because of its fresh and fragrant taste characteristic of seafood, kelp is very popular among people. Kelp is known as the "longevity vegetable". It contains abundant protein, amino acids, vitamin B, C and trace elements such as calcium, iron and iodine. At the same time, the protein and other components in kelp are easily absorbed by human body. If reasonably combined with other materials, kelp soup with different tastes and medicinal value can be made. Kelp shrimps soup can supplement both iodine and calcium. The iodine content of kelp is quite rich, almost 100 times of that of grains and vegetables.
