Whether a cup of java will leave you craving more could be chalked up to your genes.
一杯咖啡是否会使你上瘾也许是由你的基因决定的。
People with a newly identified genetic variant in their DNA, called PDSS2, may be inclined to drink fewer cups of coffee than others, according to a small study published in the journal Scientific Reports.
根据发布在《科学报告杂志》上的一项小研究显示:有这种新发现的遗传变异PDSS2基因的人,可能会倾向于比其他人喝更少的咖啡。
"I actually was very surprised to find a new gene for coffee consumption," said Nicola Pirastu, a chancellor's research fellow at the University of Edinburgh's Usher Institute of Population Health Sciences and Informatics, and lead author of the study.
爱丁堡大学厄舍学院人口健康科学和信息学研究员,同时他也是这篇研究的主撰写人的尼古拉·皮拉斯图表示:“能找到关于咖啡消费量的新基因真的使我非常惊讶。”
"We believe that this PDSS2 genetic variant is impacting coffee drinking through the regulation of the speed at which caffeine is metabolized," he said. "It has been observed before that higher levels of PDSS2 inhibits the expression of the genes metabolizing caffeine and thus the speed at which caffeine is degraded."
他说道:“我们认为这种携带PDSS2基因突变是通过咖啡因的常规新陈代谢速度来影响咖啡的饮用量的,我们观察到这种现象是在人体释放更多的PDSS2来抑制咖啡因的代谢之前,因此咖啡因的代谢由此减慢。”
