Dozens of edible varieties of seaweed—the broad term for 10,000-plus types of marine plants and algae—are high in minerals, fiber, antioxidants, and sometimes protein. Plus, seaweed is self-propagating and sucks up excess carbon dioxide, nitrogen, and phosphorus from the ocean. This means health-conscious enviros can feel good about savoring its unique flavor in drinks, snacks, seasonings, and even spirits.
