Summary
Seaweed and other algae contain special fibers called polysaccharides that act like fertilizer for beneficial bacteria in your gut. When these good bacteria ferment these algal fibers, they produce substances called short-chain fatty acids that support digestive health, boost immunity, and help control blood sugar and weight. These algae-based fibers are sustainable alternatives to synthetic prebiotics and can be added to foods and supplements.
Background
Micro- and macroalgae are rich sources of polysaccharides with prebiotic potential and functional food applications. These organisms contain diverse bioactive compounds including fucoidan, laminarin, alginate, and carrageenan that can modulate gut microbiota and support health.
Objective
This review comprehensively examines algal polysaccharides as prebiotics and functional fibers, focusing on their interactions with gut microbiota, health benefits, and food applications. It provides comparative analysis between sulfated and non-sulfated polysaccharides while addressing safety concerns and regulatory frameworks.
Results
Algal polysaccharides demonstrate prebiotic effects by increasing short-chain fatty acid production and modulating beneficial bacteria such as Bifidobacterium and Lactobacillus. They exhibit anti-inflammatory, antioxidant, antimicrobial, and immunomodulatory properties. However, carrageenans show pro-inflammatory effects in some studies.
Conclusion
Algal polysaccharides represent promising sustainable sources for functional food development with multiple health benefits. Further research is needed to standardize assessment methods, address safety concerns including heavy metal accumulation, and establish regulatory frameworks for these emerging prebiotics.
