Before you dismiss the possibility of ever consuming seaweed, consider this: Most of you probably eat processed sea vegetables every day. They're used as thickeners and stabilizers in a variety of packaged foods. But the greener, more nutritious, and certainly most delicious way to indulge in seaweed is in its unprocessed form. We're talking about safely edible marine algae found on or near ocean shores that can be a valuable source of a wide array of nutrients. Sea vegetables are believed to be detoxifying and beneficial to the thyroid. In a Macrobiotic lifestyle, they are used to "cleanse the lymphatic system, stimulate stagnant liver energy, alkalize the blood." In fact, their concentrated nutrient profile has led to the suggestion that sea vegetables only be consumed in relatively small quantities.
