Postbiotics

Scientists call the bacteria-derived compounds postbiotics. They are not like probiotics, which are whole, live bacteria people take to change the microbial environment of the gut to ward off disease and improve digestion.

Postbiotics instead are beneficial pieces of bacteria cell walls that are easily absorbed by the body, which seem to make insulin work better. Postbiotics can also be derived from disease-causing microbes, say researchers.

Based in these results, Rescigno and coworkers has recently proposed the concept of postbiotics, meaning metabolites produced upon microbial fermentation that may have bioactive capacity and that could be useful for modulation of host response in cases of inflammatory diseases ( Tsilingiri and Rescigno, 2013 ).
