New research says that DNA helps decide whether we prefer coffee or tea. Researchers from a university in Australia find out how our DNA changes our taste, and why we like some things more than others. The researchers think they know why some of us prefer coffee while others like tea more. People who like bitter(苦的)tastes are more likely to drink coffee. The researchers said they found something strange in their research. People who are more sensitive(敏感的)to the bitter taste of caffeine are more likely to prefer coffee to tea. They also drink more coffee than those who were not so sensitive to caffeine.
　　Researchers looked at the data on more than 400, 000 people in the U.K. and they also looked at an Australian study about the tastes of 1, 757 twins and their brothers and sisters. They find that other things can also change our taste, like environment, social factors( H素)or medicine. One researcher thinks we can learn to like coffee. He said, “Bitter taste is changed not only by DNA, but also some environmental factors. Even though we dislike bitterness, we can learn to enjoy bitter-tasting food.”
