Kelp is a brown seaweed. Most seaweeds are divided into three groups according to their color, either green, brown, or red. Generally, the green seaweeds inhabit the shallowest zones along the shore. The browns live in the mid-intertidal and subtidal zones, and the reds are usually found in deeper waters. Just like mushrooms, there are hundreds of species and varieties of seaweed. Certain ones are edible, and of those, some are rare and prized for their nutritional value, like certain species of kelp. It is the tissues of the kelp species that contain the highest concentration of minerals and vitamins. Kelp is usually found in cold waters, and is very fast growing. The most concentrated source available, kelp provides key vitamins and minerals missing in the typical North American diet.
