Impact of Marine Algal Polysaccharides on Gut Microbiota and Health

Seaweed polysaccharides are immunomodulators that are essential for controlling the host's immunological response. The host's nutritional intake and the diversity of gut microbes are two examples of factors that affect the immune response. East Asian populations have traditionally used seaweeds in their staple meals, and their bioactive components may one day be used as functional foods. As a result, it is now critical to research how seaweed can modify the composition of gut microorganisms to improve human health. The study will conduct a comprehensive literature review to identify what is known about the effects of seaweeds on the gut flora. Studies investigating the impact of seaweed on gut flora were discovered by searching relevant databases.  The findings demonstrated that seaweed significantly increases the generation of SCFA and has a prebiotic effect on digestive systems. Seaweed polysaccharides have been shown in studies to control intestinal metabolism and may help treat inflammatory bowel disease. The review's findings demonstrated that eating seaweed benefits both the host and the gut bacteria.
