Marine plants, either marine algae or seaweeds, were part of the daily diet of our ancestors and have been consumed in different parts of Asia for centuries. Although plants like kelp, nori, dulce, and spirulina are more commonly used in sushi, Asian soups, snacks, or seasonings, there are many other varieties of sea plants packed with important nutrients. These sea vegetables absorb beneficial nutrients from the ocean and are very good sources of protein, fiber, healthy polyunsaturated fats, antioxidants, and vitamins and minerals. For example, after iodized salt they are the second richest source of iodine, and it is well known that iodine is critical for a healthy thyroid gland. Thyroid hormones - thyroxine (T4) and tri-iodothyronine (T3) - play a vital role in growth and development of the body and in regulating various metabolic processes, including basic metabolic rate, healthy functioning of the brain, heart, immune and digestive systems, and building strong muscles and bones. Two sea plants which contain critical nutrients for overall health are Irish moss and bladderwrack.
