摘要:

高脂饮食对阿尔茨海默病(Alzheimer’s disease, AD)的发病有着重要的作用,该文在总结 AD 可能的 发病机制基础上,进一步阐述了高脂饮食导致 AD 发生的可能机制:增加血浆中饱和游离脂肪酸的含量,加快 AD 的病理进程;通过影响血脂水平促进 AD 的发生;导致大量脂肪的产生,并引起慢性炎症,产生的炎症因子 穿过血脑屏障从而激发神经炎性细胞;高脂肪食物影响肠道菌群,进而影响到微生物群 - 大脑 - 肠道的轴,导致 AD 的产生。基于以上机制,可以从减少游离饱和脂肪酸、调节脂代谢紊乱、改善炎症、调节肠道菌群这些机制 来治疗或者预防 AD 的发生。

Abstract:

High-fat diet plays an important role in the pathogenesis of AD. This paper reviews the possible pathogenesis of Alzheimer’s disease in recent yearsand further expounds the possible mechanism of high fat diet causing Alzheimer’s disease:High fat diet increases the content of saturated free fatty acids in plasma and speeds up the pathological process of AD; High fat diet promotes the occurrence of AD by influencing blood lipid levels;A high-fat diet will lead to the production of large amounts of fat and cause chronic inflammationthe inflammatory factors produced cross the blood-brain barrier and stimulate neuroinflammatory cells;High-fat food will affect the gut bacteriawhich in turn affect the microbiota - brain - gut axisthen lead to the AD. Based on the above mechanismswe can treat or prevent AD by reducing free saturated fatty acidsregulating lipid metabolism disordersimproving inflammationand regulating intestinal flora.

Key words: high-fat diet, Alzheimer’s disease, free saturated fatty acids, blood lipid, inflammatory factors, intestinal flora
