Did you know that the amount of coffee you drink could have something to do with your DNA? A new study by Edinburgh University has identified that your genes can have a direct impact on your coffee consumption.
According to the new report, people who possess a specific gene called PDSS2 usually drink less coffee than those without the gene. This is because the gene reduces the ability for the body to breakdown caffeine and therefore means you need less coffee to get your caffeine boost.
Researchers surveyed over 1200 people in Italy and found that those without the gene PDSS2 drank an average of one extra cup of coffee per day.
These results back up previous studies which show links between genetics and coffee consumption, although larger studies are needed to confirm the findings.
So next time you feel a craving for coffee it could be down to your DNA!
