Why is kelp so good?

Why is kelp considered so beneficial? Could you elaborate on its nutritional value and potential health advantages? I've heard it's rich in minerals and vitamins, but I'm curious to know more about its specific benefits. Is it a good source of protein? Does it contain antioxidants? How does kelp support a healthy diet? I'm interested in incorporating it into my meals, but I'd like to understand its nutritional profile first. Could you please provide more insights into why kelp is so highly regarded?
