New research suggests that our DNA helps us to decide whether we prefer coffee or tea. Researchers from University of Queensland in Australia studied how our genes affected our taste and why we like some tastes more than others. Following research, researchers believe they know why some of us prefer coffee while others like tea more. researchers found that people who like more bitter tastes are more likely to drink coffee. researchers said they found something strange in their research. People who were more sensitive to bitter taste of caffeine were more likely to prefer coffee to tea. They were also more likely to drink more coffee than those who were not so sensitive to caffeine.

Researchers looked at data on more than 400,000 men and women in United Kingdom. They also looked at Australian study that compared tastes of 1,757 twins with their siblings. researchers said genes aren't only factors affecting people's tastes. Other things like our changing environment, social factors or effects of taking medicine can also turn us on or off coffee or tea. researchers said we can learn to like coffee. Dr Liang-Dar Hwang said: "Bitter taste perception is shaped not only by genetics, but also environmental factors. Even though humans naturally dislike bitterness, we can learn to like or enjoy bitter-tasting food after being exposed to environmental factors.
