Seaweed, kombu, dried, raw

Kombu is a type of edible seaweed. The figures here describe dried, raw kombu, rather than kombu that has been soaked or cooked. It provides protein and minerals, including calcium and iodine. Per 100g, it contains 7.1g of protein, 900mg of calcium, 4.6g of salt and 440670µg of iodine.

Iodine is needed to make thyroid hormones, which help regulate the body's metabolism. The iodine content listed is very high, and excessive iodine intake can affect thyroid function. The salt content is also relevant for people monitoring their salt intake. Full nutrient figures are provided in the tables below.
