Abstract:A white kidney bean α-amylase inhibitor functional food was prepared by nano-liposome， and a volunteer experiment was conducted to analyze the lipid-lowering and weight-reducing function of nano-white kidney bean α -amylase inhibitor liposome functional food . The results showed that the body weight， BMI， LDL-C， TC， TG and fecal fat percentage of the experimental group were significantly lower than those of the control group after 90 days of continuous treatment（P <0.05）. This nano-lipid functional food had sufficient se－ curity， the development of nanometer lipid functional food was impacted significantly in sports and health indus－ try.
