Dietary Polysaccharides for Gut Health and Growth Performance
Summary
Dietary polysaccharides are complex carbohydrates derived from plants, algae or microorganisms that resist host digestion and reach the lower gut, where they serve as fermentable substrates for resident microbiota. Their fermentation yields short-chain fatty acids and other metabolites that strengthen epithelial barrier integrity, modulate mucosal immunity and influence nutrient absorption. In livestock, inclusion of polysaccharide-rich extracts has been shown to enhance growth rates by improving feed conversion, reducing intestinal inflammation and supporting antioxidant defences. Beyond animal production, these macromolecules attract interest for human health through their prebiotic activity, potential to balance gut microbiota and capacity to replace prophylactic antibiotics. Advances in extraction methods and characterisation of structure–function relationships continue to expand practical applications of dietary polysaccharides, linking molecular architecture to performance outcomes at a farm-scale and informing translational opportunities in nutrition and medicine.

Dietary Polysaccharides for Gut Health and Growth Performance publication trend
The graph below shows the total number of articles in dietary polysaccharides for gut health and growth performance across all publications each year (not limited to Nature Index journals).
Technical terms
Dietary polysaccharide: A high-molecular-weight carbohydrate resistant to host digestion but fermentable by gut microbes.
Gut microbiota: The community of bacteria, archaea, fungi and viruses residing in the gastrointestinal tract.
Short-chain fatty acids (SCFAs): Fermentation products (e.g., acetate, propionate, butyrate) that nourish colonocytes and modulate host metabolism.
Intestinal barrier integrity: The functional and structural features—mucus layer, epithelial tight junctions—that prevent pathogen translocation.
Villus height to crypt depth ratio: A histological indicator of nutrient absorption capacity, calculated from small-intestinal mucosal architecture.
Immunomodulation: The alteration of immune responses, often through regulation of cytokines and cell-surface receptors.
