People I can’t understand are people who don’t like coffee. To me they look like aliens, a day without caffeine is a nightmare for me. But it seems that coffee preference is not only a matter of taste, but also depends a lot on our genetics.
A recent study published in the journal Psychopharmacology sheds light on how our genetic makeup is related to our coffee drinking habits.
The study used data from 464,812 participants who reported their daily caffeine consumption. They also provided genetic information by providing a saliva sample. Researchers conducted genome-wide association studies to identify specific genetic variants associated with its consumption.
Is drinking coffee hereditary?
It is quite interesting that the researchers came to the conclusion that coffee consumption is a hereditary trait, that is, genetic factors contribute significantly to the amount of consumption of individuals.
The researchers were also able to identify specific genes that affect its consumption, including some that affect how quickly caffeine is metabolised.
However, it is important to note that our genes are not our destiny. A number of other factors can affect how much coffee we drink on a daily basis. Of course, the need for caffeine consumption is greater after a sleepless night, and if you are sick, you may not want to drink coffee. Genes and environment can combine to influence a person’s caffeine consumption habits.
