Prebiotics are defined as “undigestible food ingredients that beneficially affect the host by selectively stimulating the growth and/or activity of one or a limited number of bacterial species that are already established in the colon and therefore improve the health of the host"
Prebiotics are non-digestible food components (usually carbohydrates or fibers) that selectively stimulate the growth or activity of beneficial gut bacteria, mainly Bifidobacteria and Lactobacilli.
Their anticancer effects arise primarily through modulation of the gut microbiota, immune regulation, and production of protective metabolites like short-chain fatty acids (SCFAs) — especially butyrate.
