Nori is normally sold in dried sheets. It is one of the easist ways to eat seaweed. Nori is best used to wrap around small rice balls which are then dipped in shoyu. After soaking, Nori can be added to soup or used as a salad ingredient.
Nori, and all other seaweed, is a rich source of calcium, zinc and idoine. It is also a good source of Lignans which help fight cancer.
Because it comes from the sea, seaweed contains sodium and anyone on a sodium-restricted diet should be careful with the amounts they eat. Wakame has the highest sodium content, with kelp and laver having significantly less.
