Seaweed contains a diverse range of nutrients that vary significantly based on species, environment, and harvest time. Learning what is seaweed made of requires understanding its cellular structure, nutritional content, and the unique compounds that define each major group.

Globally, over 70 species of marine algae are recognized as edible, and humans have consumed macroalgae like seaweed for thousands of years. The answer to "can you eat cooked algae" is a resounding yes, provided you select the correct species and prepare them safely. Different types, from microalgae like spirulina to macroalgae like kombu, are cooked and used in diverse culinary applications, from soups to snacks.

The class of brown algae, Phaeophyceae, includes over 1,800 species, representing the most diverse and complex group of marine algae. This article explores the defining characteristics and diverse forms that comprise the different types of brown seaweed.

According to a study on edible macroalgae, some red species like *Palmaria palmata* can contain over 2000 ppm of iodine, proving that there is indeed **iodine in red algae**, but content varies significantly by species and other factors. This trace mineral is essential for thyroid function, but moderation is key to avoid health risks from excess intake.

According to scientific research, certain marine macroalgae species can bioaccumulate minerals like potassium to levels hundreds of times higher than seawater. This mineral-rich profile confirms that yes, algae contain potassium, and in many cases, are an exceptional source of it.

Algae, a diverse group of photosynthetic organisms, is considered by many researchers to be a complete and highly bioavailable food source. This unassuming organism, which ranges from microscopic microalgae to large seaweeds, is gaining traction as a sustainable superfood due to its exceptional nutritional profile.

Over 10,000 species are classified as seaweed, a broad term for marine macroalgae. So, what is the difference between kelp and seaweed? Kelp is actually a specific type of large brown seaweed, not a separate entity, with distinct features related to size, habitat, and structure.

Surprisingly, seaweed is not a plant; it is a macroscopic marine alga belonging to a diverse and ancient lineage. Understanding what classification does seaweed belong to reveals that it's not a single taxonomic entity but a common term for different groups of organisms, primarily brown, red, and green algae.

According to a 2024 study, iodine concentrations in macroalgae were significantly higher than in microalgae. For those asking, "is microalgae high in iodine?" the answer is generally no, especially when compared to many marine macroalgae species, though certain types can be biofortified or grown in high-iodine environments.

With the global seaweed market projected to grow significantly, algae is a recognized superfood with deep historical roots. The question of what algae is used as human food is increasingly relevant as people seek sustainable and nutrient-rich food options.
