I found the interesting article about Seaweed (Kombu/Wakame/Nori). Please refer the following URL.  Nori is a skin superstar, Wakame beats the Bloat, and Kombu is the metabolism booster. Kombu is valuable for its high content of Iodine, which is needed to produce two important thyroid hormones that control the metabolism. And also, there is a pigment in Kombu called “Fucoxanthin” , which may boost production of a protein involved in fat metabolism.  Kombu has good nutrition and the reason why we call Kombu “King of Seaweed”.
