Seaweed is a popular stable in the Japanese diet. The three most popular seaweed products in Japan are nori (Porphyra), wakame (Undaria) and kombu (Laminaria). Kombu seaweed is an edible kelp found in the sea forests, also known as kelp forests. These forests are very beneficial by providing an important ecosystem for the organisms that live between the seafloor and the surface of the ocean. As such, the seaweed absorbs a vast array of nutrients, making it a powerful, health-promoting food. Fresh or dried kombu can be used in a variety of bean, salad, soup and pickle dishes. It can also be an ingredient for sauces and stocks, or enjoyed on its own to introduce health benefits to your diet.
