Porphyra spp. is a widely edible marine red algae that has attracted much attention for its rich nutritional value and significant antioxidant activity. This study systematically analyzes the nutritional composition, functional compounds and their antioxidant properties of seaweed, and explores the potential benefits of seaweed intake for human health. Seaweed has high protein content, complete types of essential amino acids and appropriate proportions; it is rich in carbohydrates and dietary fiber, and has significant vitamins and minerals. Seaweed is rich in functional ingredients such as polyphenols, carotenoids, phycobilidins and sulfate polysaccharides, making it have significant antioxidant activity and a variety of biological functions. Studies have shown that seaweed extract has the ability to scavenge free radicals and may play an active role in anti-inflammatory, immune regulation, cardiovascular health protection, as well as anti-tumor and anti-aging. This study sorts out the results of research on nutrition and function of seaweed in recent years and discusses future research and application directions.
