Hot topics in gut microbiota.

The study of gut microbiota is a rapidly moving field of research, and the impact of gut microbial communities on human health is widely perceived as one of the most exciting advancements in biomedicine in recent years. The gut microbiota plays a key role in digestion, metabolism and immune function, and has widespread impact beyond the gastrointestinal tract. Changes in the biodiversity of the gut microbiota are associated with far reaching consequences on host health and development. Further understanding of the importance of developing and maintaining gut microbiota diversity may lead to targeted interventions for health promotion, disease prevention and management. Diet, functional foods and gut microbiota transplantation are areas that have yielded some therapeutic success in modulating the gut microbiota, and warrant further investigation of their effects on various disease states.
