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:
这项发表在《科学报道》期刊上的研究涵盖了两组数据。第一组来自一对大型双生研究，他们显示出一些特定的遗传型关系到我们对不同味道的感知能力，至少对于欧洲裔的人来说是这样的：
one specific variant was associated with slightly higher ratings of bitterness for caffeine, another to greater bitterness for quinine and a third to greater bitterness for a drug known as propylthiouracil, or prop.
其中一种遗传型让人更容易感知咖啡因的苦味，另一种型让人更容易感知奎宁的苦味，第三种型让人更容易感知一种叫丙基硫氧嘧啶的药物的苦味，这种药物简称prop。
The team found people with a greater genetic predisposition to perceiving the bitterness of caffeine drank a little more coffee, but an increased perception of the bitterness of quinine and prop were linked to a small reduction in coffee drinking.
研究团队发现，那些更容易感受咖啡因苦味的人喝的咖啡要更多一些，而更容易感受奎宁和丙基硫氧嘧啶苦味的人喝的咖啡要少一些。
“While the effect of perception on your daily coffee intake might be relatively small – only a 0.15 cup per day increase – from a normal caffeine taster to a strong caffeine taster, it actually makes you 20% more likely to become a heavy drinker – drinking more than four cups per day,” said Jue Sheng Ong, first author of the research.
研究的第一作者Jue Sheng Ong说：“虽然这种感知的差异对你每天咖啡饮用量的影响比较小，重口者只比轻口者多0.15杯，但它却让你有20%更高的几率成为重度饮用者；这里的重度饮用指的是一天喝咖啡超过4杯。”
The team also found that greater perception of the bitterness of prop was linked to a lower chance of being a heavy drinker of alcohol.
研究团队还发现，那些更容易感受丙基硫氧嘧啶苦味的人成为酗酒者的几率更低。
今日词汇
perception
/pə'sepʃən/
n. 感知
这个词的意思是“感知”，与of连用。
The perception of bitterness differs among people.
