Seaweed removes fats and toxins from the body and helps protect the liver from toxic damage. Certain seaweed varieties are some of the most nutritionally dense plants on the planet. They are the most abundant sources of minerals in the plant kingdom because they have access to all 92 minerals needed for nutrition in the ocean. Seaweeds have an extraordinary capacity to accumulate minerals, becoming increasingly rich in sodium, potassium, calcium, magnesium, chlorine, iron, sulfur, copper, manganese, cobalt, bromine, iodine, and many naturally occurring vitamins, including A and C.
In addition, seaweeds utilize nitrogen from the air to synthesize complete proteins. The sodium alginate in seaweed, especially kelp, absorbs toxins from the digestive tract. A Canadian study from McGill University found that seaweed absorbs cadmium and lead from inside the body, which can accumulate from cigarette smoke and industrial waste in the environment. Green seaweed is also a potent detoxifier because of the chlorophyll in it, which contains special fibers that bind and remove unwanted toxins.
