New research suggests that our DNA helps us to decide whether we prefer coffee or tea. Researchers the University Queensland Australia studied how our genes affected our taste and why we like some tastes more than others. Following the research, researchers believe they know why some us prefer coffee while others like tea more. The researchers found that people who like more bitter tastes are more likely to drink coffee. The researchers said they found something strange their research. People who were more sensitive to the bitter taste 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 data more than 400,000 men and women the United Kingdom. They also looked an Australian study that compared the tastes 1,757 twins their siblings. The researchers said genes aren't the only factors affecting people's tastes. Other things our changing environment, social factors or the effects taking medicine can also turn us or off coffee or tea. The researchers said we can learn to like coffee. Dr Liang-Dar Hwang said: "Bitter taste perception is shaped not only genetics, but also environmental factors. Even though humans naturally dislike bitterness, we can learn to like or enjoy bitter-tasting food being exposed to environmental factors.
