The oral administration of pure monosaccharides is effective for improving intestinal function such as nutrient digestion and absorption. However, day-to-day diets tend not to include high purity monosaccharides for intestinal health. Honey possesses large amounts of monosaccharides including glucose and fructose in the same ratio. In this study, we have evaluated the nutritional properties of honey and examined the effects of its oral ingestion on the recovery of intestinal function in the total parenteral nutrition (TPN) rat model. It was observed that honey remarkably recovered the function of the small intestine including the villous morphology, nutrient digestion, and absorption capabilities. In particular, the expression of disaccharidase was significantly enhanced by the ingestion of honey after TPN treatment. Therefore, oral intake of honey is effective in recovering and maintaining small intestinal functions and can potentially be used as a supplement for promoting small intestinal function recovery.
