What it is

Dried nori is a type of edible seaweed, specifically a red algae. It is cultivated in the ocean, harvested, and then dried into thin sheets. Nori is a staple in Japanese cuisine and is widely used for its savory flavor and nutritional content.

Why it's used

Nori is primarily used as a wrapper for sushi rolls and onigiri (rice balls). It can also be crumbled and used as a seasoning for soups, noodles, and rice dishes. Manufacturers use it for its distinct umami flavor and to add a visual appeal to packaged foods.

Health notes

Nori is generally recognized as safe (GRAS) by the FDA for use in food. It is a good source of iodine, vitamins, and minerals. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has evaluated nori and found it to have no safety concerns. Due to its iodine content, excessive consumption could potentially affect thyroid function in sensitive individuals, but this is not a concern at typical dietary intake levels.

Allergen info

Nori is not one of the nine major allergens identified by the FDA. It is also naturally gluten-free.
