About Seaweed, kelp, raw

Kelp is a large brown seaweed harvested from cold coastal waters and used for centuries across East Asian cuisines — Japanese kombu is kelp, the foundation of the savory dashi stock that underpins so much Japanese cooking. It has a deep, briny, umami flavor.

At about 43 calories per 100 grams it contributes fiber and a broad sweep of minerals, including calcium, magnesium and iron. Its defining feature, though, is iodine: kelp is one of the richest natural sources on earth, which is genuinely useful for thyroid health in small amounts — but easy to overdo.

Because its iodine content is so high and variable, kelp is best treated as a flavoring used in modest amounts rather than a vegetable eaten in bulk; very large or frequent servings can supply far more iodine than the body needs. A strip of kombu simmered into stock, or a sprinkle of kelp flakes, is the usual way to enjoy it.
