Nori is an edible red seaweed. Dried sheets wrap sushi rolls, while toasted snacks and powders season rice, soups, or salads.
This seaweed supplies iodine for thyroid hormone production. It also provides vitamins A, C, and B12 alongside iron and calcium. People use it as a nutrient-dense, plant-based food.
Nori sheets are eaten raw or lightly toasted. Powdered nori mixes easily into meals. Watch iodine intake if you have a thyroid condition, since high amounts can shift hormone balance.
