摘要
背景:非酒精性脂肪肝疾病(NAFLD)在全球范围内影响着数百万个人,目前尚无金标准治疗方法。随着体重指数的增加,发展NAFLD的风险要高得多。因此,应建议所有超重脂肪肝患者减轻体重。但是,无论体重状况如何,生活方式干预也可能影响病情。本文的目的是提供评估饮食相关成分对肝脂肪变性的直接作用的短期干预措施的实例。 方法:本综述包括长达16周的与饮食相关的短期干预措施的研究,这些干预措施评估了它们减少肝内脂质含量(肝脂肪变性)的功效。这篇综述主要关注三种主要的常量营养素:膳食碳水化合物,脂肪和蛋白质。 结果:据报道,饱和脂肪的高摄入量和碳水化合物的高消耗,特别是来自单糖(例如果糖)的碳水化合物,是肝脂肪变性的危险因素。总体而言,短期低热量饮食已显示出降低肝内脂质含量的有益作用。大量营养素的操作,例如限制碳水化合物的消耗以及不饱和脂肪酸的消耗也据报道具有有效的作用。 结论:这篇综述强调了短期内可以影响肝脂肪变性的不同饮食干预措施,说明了其对脂肪变性的促进作用和抗脂肪变性作用。
