Prebiotics are substrates that are selectively utilized by host microorganisms, conferring a health benefit. According to the definition of the International Scientific Association for Probiotics and Prebiotics (ISAPP), prebiotics must possess three core characteristics: 1) resistance to gastric acidity, hydrolysis by mammalian enzymes, and gastrointestinal absorption; 2) fermentation by intestinal microorganisms; and 3) selective stimulation of the growth and/or activity of beneficial bacteria (such as Bifidobacteria and Lactobacilli), thereby improving host health. The essence of prebiotics is dietary fiber, i.e., the indigestible part of food. Unlike ordinary soluble dietary fiber, which can only be broadly utilized by about 30% of gut microbiota, qualified prebiotics can selectively stimulate the proliferation of core beneficial bacteria such as Bifidobacteria and Lactobacilli, increasing the proportion of beneficial bacteria in the gut from about 25% in the general population to over 70% in a healthy state—this is the core difference between prebiotics and ordinary dietary fiber. The relationship among dietary fiber, prebiotics, and probiotics is: Dietary fiber is the foundation, a portion of which can act as prebiotics; prebiotics feed probiotics; probiotics maintain intestinal health. A high-fiber diet itself can create a favorable gut microbiota environment. This report covers the four most important types of prebiotics: Inulin, Fructo-oligosaccharides (FOS), Galacto-oligosaccharides (GOS), and Xylo-oligosaccharides (XOS).

Prebiotics have multiple positive effects on human health:
