Abstract:
Functional sugars mainly comprise functional oligosaccharides, functional dietary fibers, and functional sugar alcohols. Functional sugars, especially functional oligosaccharides, are the most common prebiotics, which promote intestinal motility, protect the gut mucosal barrier, regulate intestinal flora, and improve body immunity. However, some people develop abdominal distension upon taking functional sugars; hence, compliance in taking functional sugars is affected and the efficacy is reduced. The cause of functional sugar-induced abdominal bloating is not clear. In this study, the causes of abdominal distension induced by functional sugars and the methods to detect them were identified and analyzed based on the relevant reports at home and abroad. Abdominal distension induced by functional sugars was found to be related to an increase in intestinal gas and water levels, the abnormal distribution of intestinal gas, and the sensory impairment of intestinal contents. A variety of intervention methods, including the adjustment of functional sugar formulae, regulation of intestinal flora, promotion of gas emission, and reduction of visceral perception, were also identified. It is beneficial to improve compliance in taking functional sugars to improve their effectiveness in preventing and treating diseases.
