This is the text (if you need help).
Our DNA affects whether we like coffee or tea. Researchers studied how our DNA did this. The researchers said people who like bitter tastes are more likely to drink coffee. People who are sensitive to the bitter taste of caffeine will drink coffee. They will also drink more coffee than people who are not sensitive to caffeine.
Researchers looked at data on more than 400,000 people. They said other things can also affect our taste, not just DNA. A researcher said our environment, social factors or medicine can change our taste. He said we can even learn to like or enjoy bitter-tasting food and drink.
