Kelp
A type of seaweed that is a rich source of iodine and other essential minerals.
Also known as: Seaweed • Laminaria
Overview
Kelp is a large, brown seaweed that grows in underwater forests in shallow, nutrient-rich waters. It is a highly nutritious food that is rich in vitamins, minerals, and antioxidants. Kelp is one of the best natural sources of iodine, an essential mineral that is crucial for thyroid function. The thyroid gland uses iodine to produce hormones that regulate metabolism, growth, and development. In addition to iodine, kelp is also a good source of other minerals, such as potassium, magnesium, calcium, and iron. It also contains a variety of vitamins, including vitamin K, vitamin A, and folate. The high antioxidant content of kelp helps to protect the body against damage from free radicals, which can contribute to chronic diseases. Kelp can be eaten raw, cooked, or in powdered form as a supplement.
