挑对时间吃饭 远离脂肪肝

俗话说:早餐吃得像皇帝,午餐吃得像平民,晚餐吃得像乞丐。


近日,美国第三次全国健康和营养调查(NHANES III)数据分析也证实了这一观点,即特定的饮食行为可降低非酒精性脂肪性肝病的风险。若增加每天的卡路里量在上午时段的摄入比例(早餐吃得像皇帝),可降低14%-21%的脂肪肝发生风险。


非酒精性脂肪性肝病(NAFLD)是一种与胰岛素抵抗和遗传易感密切相关的代谢应激性肝脏损伤,其病理学改变与酒精性肝病(ALD)相似,但患者无过量饮酒史,疾病谱包括非酒精性单纯性脂肪肝(NAFL)、非酒精性脂肪性肝炎(NASH)及其相关肝硬化和肝细胞癌。NAFLD是21世纪全球重要的公共健康问题之一,亦是我国愈来愈重要的慢性肝病问题。


非酒精性脂肪性肝病(NAFLD)是在无过量饮酒的情况下,脂肪过量积累于肝脏所引起的肝脏损伤。危险因素包括:高脂肪高热量膳食结构、多坐少动的生活方式,胰岛素抵抗、代谢综合征及其组分(肥胖、高血压、血脂紊乱和2型糖尿病)。


有研究表明,肝脏与人体其它器官一样,遵循24小时生物钟或昼夜节律。进食时间被认为是肝脏维持一天24小时周期的外在提示。也有研究提示,轮班工作可能会增加糖尿病和肥胖症的发病风险。


与过去相比,现代社会中有更多人上夜班或经常熬夜,这打乱了正常的睡眠和饮食模式。为了探明特定饮食时间模式是否会影响非酒精性脂肪性肝病的发生风险,研究者将一天划分为四个时间段,大致与进食时间相一致:上午(04:00am-10:00am)、中午(10:00am-04:00pm)、晚上(04:00pm-10:00pm)、深夜(10:00pm-04:00am),并评估每个时间段的饮食情况及相对卡路里摄入量与脂肪肝的严重程度及肝纤维化或肝硬化的关系。


本研究已排除患有乙型或丙型肝炎、大量饮酒或服用潜在肝毒性药物的成人,并对年龄、性别、种族、吸烟和饮酒、总卡路里摄入量等变化进行调整。


结果显示,将一天的总卡路里量分成更多次进行摄入的饮食方式(少食多餐),与较低的脂肪肝和肝纤维化发生率相关。每额外增加一餐,脂肪肝和肝纤维化发生率降低10%。


进一步分析发现,若增加每天的卡路里量在上午时段的摄入比例(早餐吃得像皇帝),可使脂肪肝的发生率下降14%-21%。


此外,不吃早餐或午餐与深夜或凌晨进食的饮食方式均对身体具有潜在的危害。不吃早餐和午餐(既未在04:00am-10:00am和10:00am-04:00pm时段进食)的调查参与者,脂肪肝发生风险分别高出20%和73%。与晚上10点进食的参与者相比,深夜或凌晨进食的参与者肝纤维化的发生率高出65%。


此研究表明,通过简单的进食方式和时间调整就可以降低非酒精性脂肪性肝病的发生风险,尤其是不要错过正餐及避免深夜进食。当然,本研究数据仅显示进食时间和非酒精性脂肪性肝病之间的相关性,仍需要更多的研究以鉴别更明确或潜在的致病机制。

为什么不要约医生一起吃饭?

不是不吃饭,只是更要陪家人医生,呆在医院的时间远远长于家里,陪病人的时间远远多于家人。多数的时候,有上班的时间,没有下班的点。天还没亮透就到医院,晚上满天星辰了才能回家。值班,基本上5-6天一趟,还要连着白天上班,24-36小时连续在医院是常态。就算呆家里休息,有急诊抢救需要你,还得跑回医院。有时候还要外出充电开会,或是培训讲课,周末时间也不一定能陪家人。所以,对于家人,我们是心存愧疚的。下了班,
