一项由多国科研人员开展的研究发现,长期摄入葵花籽油和鱼油会对肝脏产生一系列不良影响,最终可能导致非酒精性脂肪性肝病。


一项由多国科研人员开展的研究发现,长期摄入葵花籽油和鱼油会对肝脏产生一系列不良影响,最终可能导致非酒精性脂肪性肝病。
 
研究人员利用大鼠模型,分析长期摄入初榨橄榄油、葵花籽油和鱼油对肝脏的影响。
 
研究者发现,随着年龄的增长,大鼠肝脏中脂肪蓄积增多;摄入不同的油时,脂肪蓄积的类型存在明显差异。
 
在上述三种油中,初榨橄榄油在保留肝功能上效果最好;而葵花籽油则可导致肝纤维化、肝脏超微结构变化、基因表达受阻、氧化应激程度增加;鱼油也会增强氧化应激,后者与衰老、线粒体电子传输链活动减弱、端粒长度改变有关。
 
长期摄入葵花籽油和鱼油导致肝脏发生的上述变化,使得肝脏最终容易发生非酒精性脂肪性肝炎。
 
研究者认为,该研究揭示了初榨橄榄油有益而其他常用食用油有害的机制,其结果可能对于预防和治疗各种肝脏疾病非常有用。
