Scientists say a genetic predisposition to perceiving the bitterness of particular substances appears to nudge us towards one beverage or the other.
科学家们说:有一个基因上的差异关系到我们如何感知特定物质苦味,它似乎决定了我们更喜欢哪种饮料。
Dr Marilyn Cornelis, co-author of the research from Northwestern University in Illinois, said: “The study adds to our understanding of factors determining beverage preferences – taste, in particular – and why, holding all other factors constant, we still see marked between-person differences in beverage preference as well as the amount we consume.”
这项研究来自美国伊利诺伊州的西北大学,其中的联合作者Marilyn Cornelis博士说:“这项研究让我们对饮料偏好的理解又深了一步,尤其是在口味方面,它同时还解释了为什么会有这样的差异;在所有其他变量控制不变的前提下,我们依然发现饮料偏好和饮用量在人与人之间有明显的差异。”
The study, published in the Scientific Reports journal, involved two sets of data. The first was a large twin study which showed that, at least in those of European ancestry, particular genetic variants are linked to the strength of perception of different tastes:
