Researchers consolidate the diverse nutritional and medicinal benefits of seaweeds, touting their potential in food, nutraceuticals, and pharmaceuticals. The study also highlights challenges and opportunities in industrial applications, calling for more research to optimize extraction and refinement processes.
By Vijay Kumar MalesuOct 2 2023Reviewed by Susha Cheriyedath, M.Sc. In a recent review published in the journal Foods, a group of researchers provided a consolidated overview of seaweeds' nutritional and medicinal values, exploring their potential applications in food, nutraceuticals, and pharmaceuticals. They also discussed the challenges and opportunities in advancing seaweed-derived products and their industrial incorporation.
Background Seaweeds, utilized since ancient times and critical for producing essential hydrocolloids, offer diverse bio-prospecting opportunities and meet rising global demands due to their unique qualities and chemical compositions. Categorized into Chlorophyta, Rhodophyta, and Phaeophyta, they play a significant role in sustainable solutions across sectors. To fully utilize their bioactive compounds, further research is needed to optimize extraction and refinement processes.
Labeled as superfoods, seaweeds exhibit exceptional mineral content, surpassing terrestrial plants and catering to human mineral deficiencies. Their minerals, a treasure influenced by species, geographic, and environmental variables, are absorbed from seawater. However, careful consumption is vital due to the presence of potentially harmful minerals.
A schematic illustration of seaweed primary and secondary metabolites and their possible application as bioactive compounds and functional foods with the desired benefits.Found primarily in brown seaweeds, fucoidans are sulfated polysaccharides with a myriad of biological properties suitable for pharmaceutical applications, showcasing immunomodulatory, anti-tumor, anti-inflammatory, and anticoagulant properties.

Researchers find education and occupation influence cardiovascular health and mortalityCardiovascular diseases such as heart attacks and strokes are the most common cause of death worldwide. According to the World Health Organization (WHO), they account for about 18 million deaths each year. The causes of cardiovascular disease are diverse and complex. International studies suggest that socioeconomic status (SES), among other factors, may have an impact on cardiovascular health. SES is defined by the educational attainment, employment status as well as income.
