Probiotics and prebiotics have attracted much attention because of their functions in regulating the intestinal microecological balance and improving the immune function of the body. The mass consumer demand for related food products is increasing year by year. Starting from the concept of probiotics and prebiotics, we elaborated on their mechanisms to regulate the intestinal flora and enhance the body’s immunity, so as to provide a reference for consumers on how to scientifically select dairy products containing probiotics and prebiotics.

Probiotics and prebiotics

In the 1960s, the term “Probiotic” was first used to refer to bacteria that are beneficial to intestinal health. In 2001, the World Health Organization officially defined probiotics as “a kind of living microorganisms that, when ingested in appropriate amounts, can bring benefits to the host’s health.” It should be pointed out that probiotics only refer to certain strains that have probiotic properties, rather than all strains.

The WHO defines prebiotics as: a type of inactive food components that can have beneficial health effects on the host by regulating intestinal microbes. Prebiotics are generally short-chain carbohydrates, including hundreds of oligosaccharides such as resistant starch and lactulose, fructooligosaccharides, galacto-oligosaccharides, and inulin. In recent years, with the deepening of intestinal microecology research, it has been clear that prebiotics can enhance the body’s immunity by improving the intestinal microecological balance and prevent the occurrence of certain diseases. Prebiotics are widely used in food products as an intestinal microecological regulator.

The efficacy of probiotics and prebiotics

At present, a large number of clinical trials related to probiotics and prebiotics have been carried out around the world. Although probiotics and prebiotics have different effects on different groups of people, their benefits to human health have been
