Study explains why people love coffee versus tea
It’s a question guaranteed to split a group of people down the middle; Do you prefer coffee or tea?

Now research suggests which drink you choose may be down to your genes. The research has been published in the latest issue of the journal Nature Scientific Reports. Scientists found coffee lovers are more likely than the average person to taste strongly the bitter caffeine the drink contains and they tend to drink less tea, which contains lower levels of caffeine.

Researchers said the fact that someone responds to bitter flavours more is written in their genes. Scores of genetic differences affect our taste receptors.

The study, led by the University of Queensland in Australia, looked at more than 400,000 Britons' drinking habits and their taste preferences through the UK Biobank genetic databse. They found that people less sensitive to caffeine drank more tea and this was particularly the case for women.

“Given humans generally avoid bitter tastes, we interpret these findings as possibly a learned behaviour: if we can perceive caffeine well we associate this with the psychostimulant properties of caffeine and so seek more coffee,” the researchers wrote.
