There is an interesting finding!
有一个有趣的发现！
Our DNA can help us decide whether we prefer coffee or tea.
我们的 DNA 可以帮助决定我们更喜欢咖啡还是茶。
Scientists in Australia studied two questions.
澳大利亚的科学家研究了两个问题。
First, how our genes affected our tastes?
第一，我们的基因是如何影响我们的口味的？
Second, why we like some tastes more than others?
第二，为什么我们会更喜欢某些味道而不是其他味道？
Following the study, scientists understood why some of us prefer coffee but others like tea more.
在这项研究之后，科学家们明白了为什么有些人更喜欢咖啡，而另一些人更喜欢茶。
The reason is simple.
原因很简单。
People who enjoy bitter tastes are more likely to drink coffee.
喜欢苦味的人更有可能喝咖啡。
Scientists noticed that some people were sensitive (敏感的) to the bitter taste of caffeine (咖啡因), so they were more likely to prefer coffee to tea.
科学家注意到，有些人对咖啡因的苦味很敏感，因此他们更可能更喜欢咖啡而不是茶。
Scientists collected the data from many countries.
科学家们收集了来自许多国家的数据。
They also found that genes aren't the only factors affecting people's tastes.
他们还发现，基因并不是影响人们口味的唯一因素。
Other things like our changing environment, social factors or the effects of taking medicine can also turn us on or off coffee or tea.
其他因素，比如不断变化的环境、社会因素或服药的影响，也会让我们喜欢或不喜欢咖啡或茶。
The researchers said we can learn to like coffee, because our favorite taste is decided not only by genes, but also by environmental reasons.
研究人员表示，我们可以学会喜欢咖啡，因为我们最喜欢的味道不仅由基因决定，也受到环境因素的影响。
Although humans naturally reject bitterness, we can learn to enjoy bitter-tasting food because of the environment.
尽管人类天生排斥苦味，但在环境的影响下，我们可以学会享受带有苦味的食物。
