Sea vegetables are virtually fat-free, low calorie and one of the richest sources of minerals in the vegetable kingdom as they have ready access to the abundance of minerals found in the ocean. Sea water and human blood contain many of the same minerals in very similar concentrations. Sea vegetables contain high amounts of calcium and phosphorous and are extremely high in magnesium, iron, iodine and sodium. One of seaweed’s most prominent health benefits is its ability to remove radioactive substances and other heavy metals from our bodies. Components of the sea vegetables bind with the toxins in the intestines rendering them indigestible and carry them out of the system. Nori is exceptionally high in vitamin A and protein. Types of sea vegetables include arame, hijiki, agar-agar, wakame, kombu, nori, sea palm, and dulse.
