Which is better, prebiotics or probiotics?

prebiotics and probiotics have their own advantages.

prebiotics can promote the growth and reproduction of intestinal beneficial bacteria in vivo, form the competitive advantage of microecology, optimize the balance of intestinal microecology, and then improve immunity to maintain the health of the body. At the same time, it can improve the intestinal microecology.

the self-structure of probiotics, such as peptidoglycan and lipoteichoic acid, can directly play the role of immune activation as antigens, or stimulate the host immune system through autocrine immune activators, so as to improve the immunity of animals, enhance the activities of innate immune cells and natural killer cells, activate dendritic cells, stimulate the body to produce cytokines, and stimulate B cells to secrete antibodies. Probiotics can stimulate the intestinal tract to produce secretory globulin A(SIgA) to protect the health of the body.

extended information

according to the definition, prebiotics should stimulate the growth of a limited number of bacteria, which will lead to the change of the balance of microbial communities in the large intestine. Batch static culture with human bacteria showed that fructooligosaccharides (FOS), galactooligosaccharides (GOS), xylooligosaccharides (XOS), isomaltooligosaccharides (IMO) and lactulose could change the flora, increase bifidobacteria and/or lactic acid bacteria, and decrease Clostridium and Bacteroides.

Three kinds of oligosaccharides which can be fully supplied in Europe are effective, namely FOS (including inulin), trans-GOS and lactulose. The prebiotic effect of FOS and lactulose was proved by molecular level in human experiments. Adding FOS to biscuits and other foods, calculated at 8g per day, also showed great efficacy.
