这句话不是玩笑,是真的! 研究证实:连呼吸都会胖...

2017-08-24 09:42:42   中国青年网

一篇最新的科学研究证实“连呼吸都会胖”这句话原来不是开玩笑!美国一项最新研究指出,家中灰尘含有干扰内分泌的环境荷尔蒙,也会造成人体肥胖。

台湾“中时电子报”8月24日报道称,美国杜克大学(Duke University)研究团队,于北卡罗莱纳州选取了11个家庭,采集屋内的灰尘作分析其中所包含的内分泌干扰物质(endocrine-disrupting chemicals, EDCs) 浓度,并确定了共44种污染物,并取自小鼠体内的脂肪前体细胞(3T3-L1)为材料,检测灰尘对细胞的影响。

研究发现,灰尘样本抽取物中有7件,会刺激小鼠3T3-L1细胞发育变为成熟的脂肪细胞,并促进三酸甘油酯的累积,另外也有9件灰尘抽取物会刺激前脂肪细胞增生,导致脂肪细胞的数量增加。

研究人员更发现,在实验室里,只要仅仅3微克的灰尘就会对3T3-L1细胞产生影响,干扰新陈代谢,引起肥胖。

报道称,这项研究发表在美国化学学会(ACS)《环境科学与技术》(Environmental Science and Technology)期刊的研究报告上。
