What it is

Seaweed refers to a variety of marine algae, including red, green, and brown types. It grows naturally in oceans worldwide and is harvested for food and other uses. Some seaweed is cultivated in underwater farms.

Why it's used

Seaweed is used in foods for its flavor, texture, and nutritional content. It can act as a natural thickener or stabilizer, and some types are used as a source of umami flavor. It is commonly found in sushi, soups, salads, and as a snack.

Health notes

Seaweed is generally recognized as safe (GRAS) by the FDA for use in food. It is a natural source of vitamins, minerals, and fiber. Some types of seaweed, like kelp, can be very high in iodine, which is essential for thyroid function but can be harmful in excessive amounts. JECFA has evaluated seaweed and its extracts. Evidence on the long-term health effects of consuming various types of seaweed is still being studied.

Allergen info

Seaweed is not one of the 9 FDA major allergens. It does not contain gluten.
