Kombu is of the same species as kelp and has a huge range of vitamins, minerals and trace minerals. It’s good for every part of you. It is particularly good for digestion and for this reason, when I cook dried beans, I add a strip of Kombu to the cooking water. Kombu usually comes dried and looks like dark green, flat strips. When cooked or simmered it becomes very tender. If I’m not in the mood to cook dried beans, I favor Eden (brand) as they cook their beans with kombu. Don’t get dizzy, but here’s a list of nutrients in kombu. Vitamin A, Vitamin B1, Magnesium, Chlorine, Potassium, Phosphorus, Sulfur, Iron, Copper, Zinc, Selenium, Manganese, Cobalt, Boron, Nickel, Molybdenum, Iodine, Calcium, Fiber, Protein, and Folate.
