Abstract: 2’-fucosyllactose (2’‐FL) is one of the most abundant oligosaccharides in breast milk of human, which is resistant to digestion and can reach the colon where it is fermented to affect intestinal health. 2’‐FL has been authorized to be used as a nutritional supplement for infant formula and ordinary food in America and Europe, but its application has not yet been approved in China. This paper aims to discuss the effect of 2’‐FL on the gut microbiota, intestinal barrier and intestinal immunity. A number of studies indicated that 2’‐FL reshape the composition of gut microbiota, especially by promoting the proliferation of Bifidobacterium. 2’‐FL maintains the intestinal barrier integrity by increasing the expression of intestinal epithelial tight junction protein and promoting the differentiation of intestinal epithelial cells. In addition, 2’‐FL has been shown to maintain the homeostasis of intestinal immunity and promote intestinal immunity maturation in both animal and clinical researches.

Key words: 2’-fucosyllactose, gut microbiota, intestinal barrier, intestinal immunity
