Abstract
The consumption of seaweed products has gained the public’s attention due to various bioactive compounds therein, which are known to have health benefits in obesity-associated metabolic disturbances, cardiovascular diseases, hyperglycemia, and insulin resistance. This review discusses the biological functions of bioactive compounds, such as peptides, polyphenols (phlorotannins and bromophenols), polysaccharides (alginate, fucoidans, laminarin), carotenoids (fucoxanthin), and phytosterols, abundant in Undaria pinnatifida (Sea Mustard, Miyeok, Wakame), Saccharina japonica (formerly Laminaria japonica; Kelp, Dasima, Kombu), and Saccharina latissima (Sugar kelp). Although seaweed products show promising preventive and therapeutic effects of seaweed products, it is crucial to consider potential health risks. Therefore, this review addresses health concerns related to heavy metal contamination and high iodine contents, particularly associated with the consumption of brown seaweed.
