Addict Biol:肥胖竟然是由于上瘾导致的?

2018-04-11 佚名 “细胞”微信号

肥胖症在许多国家逐渐成为了严重的健康问题,这是由于高卡路里食物的日益丰富以及口感不断提高(所谓"促肥胖环境")导致的现象。虽然我们都知道过度饮食会导致肥胖的发生,但导致暴饮暴食行为发生的原因目前仍不清楚。

肥胖症在许多国家逐渐成为了严重的健康问题,这是由于高卡路里食物的日益丰富以及口感不断提高(所谓"促肥胖环境")导致的现象。虽然我们都知道过度饮食会导致肥胖的发生,但导致暴饮暴食行为发生的原因目前仍不清楚。

为了模"促肥胖环境",来自CRG的Mara Dierssen等人给小鼠两种不同的饮食选择:高脂肪的"自助式"饮食以及在日常饮食中加入含有巧克力棒的混合食品。进一步,作者分析了小鼠在面对上述两种饮食时的表现以及摄食习惯。相关结果发表在最近一期的《Addiction Biology》杂志上。

科学家们发现,除了在逐渐变胖之外,小鼠在面对上述充满诱惑的食物的情况下还会很早地出现上瘾行为以及暴饮暴食的现象。

举例来说,当每天仅提供一个小时的巧克力供应时,小鼠将会持续性地进食。此外,作者还发现了小鼠出现类似于上瘾的"不协调"行为:即使在旁边有粗粮的情况下,还是会等待巧克力的到来。此外,巧克力饱腹感相比常规饮食要弱。

研究者们发现,摄入高脂饮食或巧克力饮食的情况下,小鼠的日常作息也会发生改变。他们在活动时间更加倾向于进食活动,而且偏好摄入能够快速消化的"零食",而非日常的"三餐"。

治疗肥胖症的一大难题就是如何防止因"控制不住嘴"导致的反弹现象。研究者们分析了肥胖反弹的情况,发现高卡路里的饮食会抑制机体控制饮食的行为,同时会对学习、动力以及其他行为的弹性造成负面影响。

基于上述结果,作者希望能够检验肥胖人群是否也会因摄入卡路里过多而出现"上瘾 "的症状。
