摘　　要：目的:综述近年抗性淀粉降脂作用及其机制的研究进展。方法:以国内外研究抗性淀粉降脂作用及其机制的代表性论文为依据,进行分析、整理和归纳。结果:抗性淀粉能降低血清中胆固醇、甘油三酯的水平,增加粪便中类固醇的排泄。其主要机制为通过减少膳食中胆固醇的吸收、影响机体中胆固醇的代谢、促进胆固醇的排泄等降低血浆中胆固醇水平;与短链脂肪酸(SCFA)通过血循环进入肝脏增强肝组织胆固醇代谢相关基因表达水平有关。食物中某些物质能与抗性淀粉相互作用,互相影响吸收或生理功能。结论:抗性淀粉能针对高血脂这个高危因素,通过一系列机制降血脂,有助于预防高脂血症、心血管疾病、脑血管意外等的发病。Objective： In order to review the role of resistant starch on blood-fat reducing and the mechanism in recent years.Methods： To analyze,summarize and organize the representative papers abroad and internal,that the role of resistant starch on blood-fat reducing and the mechanism.Results： Resistant starch could reduce the level of serum cholesterol,triglyceride and increase the discharge of steroids.The main mechanism in lowing the level of serum cholesterol is through by decreasing the absorption of cholesterol for meals,affecting the body metabolism,promoting the discharge of cholesterol;It compares with short chain fatty acid（SCFA）which can come into liver to promote the level of hepatic cholesterol metabolism correlative gene expression through by blood circulation.Resistant starch and some substances in food can affect the absorption or physiologic function of each other.Conclusion： Resistant starch can reducing blood-fat in some mechanisms and contribute to preventing the onset of hyperlipemia,cardiovascular disease？and cerebral vascular accident.
