Abstract
Dietary fiber (DF) and polyphenols can synergistically enhance gut health by modulating gut microbiota and increasing short-chain fatty acids (SCFAs) production.
- DF acts as a fermentable substrate for beneficial gut bacteria, leading to increased SCFA production.
- Polyphenols selectively influence microbial populations and contribute to beneficial bioactive metabolites.
- The combination of DF and polyphenols enhances microbial diversity and gut barrier function.
- These interactions may support metabolic and immune stability in the host.
- The degree of health benefits is affected by the structural features of DF and the type and amount of polyphenols consumed.
- Further investigation is needed to optimize DF-polyphenol combinations for personalized nutrition and functional food development.
