Mol Psychiatry:低糖饮食或可有助于改善自闭症

2015-06-16 佚名 生物谷

面包、麦片以及其他含糖加工食品会引起血糖快速升高随后又会快速下降,相比之下,由蔬菜,水果和天然谷物搭配的饮食更加健康,其中一个重要原因是消化这些食物所需要的时间更长,从而保证血糖变化更加平稳。   在最近的一项研究中,研究人员利用自闭症小鼠模型进行了一项研究,他们发现给予小鼠类似保证糖尿病人血糖平稳变化的低糖饮食能够改善小鼠自闭症的部分症状,虽然这只是一个非常初步的研究结果,并且还没

面包、麦片以及其他含糖加工食品会引起血糖快速升高随后又会快速下降,相比之下,由蔬菜,水果和天然谷物搭配的饮食更加健康,其中一个重要原因是消化这些食物所需要的时间更长,从而保证血糖变化更加平稳。

 
在最近的一项研究中,研究人员利用自闭症小鼠模型进行了一项研究,他们发现给予小鼠类似保证糖尿病人血糖平稳变化的低糖饮食能够改善小鼠自闭症的部分症状,虽然这只是一个非常初步的研究结果,并且还没有在人类中进行探究实验,但这一研究成果仍为我们理解导致自闭症发生的原因提供了重要线索。
 
在过去的二十年中,自闭症患者数目急剧增加,但其中的原因一直不清楚。美国疾控中心的一些研究表明,由于自闭症定义的拓宽和诊断方法的改善,许多人都被诊断患有自闭症,因此自闭症患者数目的增加是一个不可否认的事实,而生活方式的改变可能是导致自闭症发生的一个重要因素。
 
在该项研究中,研究人员利用一株自闭症小鼠模型,对降低糖代谢的一种常见副产物--dicarbonyl methylglyoxal--的水平是否会改善自闭症症状这一问题进行了深入研究。他们给予孕鼠高糖或低糖饮食刺激,并在小鼠出生之后继续给予相应饮食处理,随后通过一种行为和生化联合检测方法对断奶后小鼠进行了相关检测,结果发现给予高糖饮食刺激的小鼠出现所有的自闭症症状,通过生化分析发现这些小鼠的新生神经元细胞更少,尤其是调控记忆的脑部区域,这种缺陷更加明显。除此之外,他们还发现饮食可能直接影响了肠道菌群生态系统,高糖饮食对自闭症发生的促进作用很可能是由于其肠道菌群对糖代谢的调节作用改变了血液中糖类中间代谢物的水平,影响了脑部神经元的发育过程。
 
综上所述,这项研究发现高糖饮食可能与促进自闭症发生有重要关联,并且这种作用可能是通过肠道菌群影响了血液中糖代谢中间产物的浓度影响了神经元的发育所导致的,但是否在人类身上具有相同疾病发生机制仍需进一步研究探讨。
