Präbiotika: Wirkungsweise und gesundheitlicher Nutzen

Summary

Prebiotics, predominantly characterized by an oligosaccharide structure, are used in functional foods. They are aimed to resist digestive processes in the upper gastrointestinal tract and to be fermented selectively by such species of the colonic microbiota which benefit health and well-being of the host. With this mode of action they only marginally differ from dietary fibre and its health effects. Until now there is a lack of evidence for a ­distinctive feature of prebiotics. Therefore, diets for better health have to include an increased consumption of dietary fibre, but not necessarily of prebiotics.

Key words

Prebiotics - dietary fibre - intestinal microbiota
