What is dried seaweed good for?

What exactly are the benefits of consuming dried seaweed? Could it possibly be a nutritional powerhouse? Does it possess unique properties that make it stand out from other food sources? Is it beneficial for weight management or does it contribute to any specific health conditions? I'm curious to know if it's a good source of essential vitamins and minerals. Could it potentially enhance my immune system? Is there any research or scientific evidence to support its purported health benefits? Moreover, how does the drying process affect its nutritional value? Is it still as beneficial as fresh seaweed? I'm also interested in knowing about any culinary uses of dried seaweed and how it can be incorporated into various dishes.
