You drink coffee every day and for many years you noticed that you cannot go longer than an hour without it. You are wondering because your office mate drinks only one cup every day and claims that the stuff can keep him up for the rest of the day. Now you are worried if something is wrong with you.

You should not be. There is a new study saying that your desire for coffee may be imbedded in your genes. This is according to the University of Edinburgh’s scientists. The scientists actually identified the gene that plays a huge role when it comes to the body’s breaking down of the caffeine. The gene is called PDSS2. This gene is capable of breaking down the caffeine gradually.

If you have this kind of gene, the body will allow caffeine to hang around a bit longer. This means that you do not need constant chug of coffee to get that feel or kick. The researchers conducted the research first in Italy where they asked 1,200 respondents to complete a survey of how many cups of coffee they consume every day.

Researchers found out that for those who have a variation of PDSS2 in their genes tend to drink less coffee – an average of one cup per day actually. To further fortify their findings, the researchers also repeated their study in Netherlands with 1,700 respondents and found similar results.

The lead author of the study, Nicola Pirastu, said that the study supports the idea that one’s desire for coffee is deeply rooted in your genes. In general, genetics play an important role in your everyday lifestyle and habits. Understanding how genetics affect your life and the people around you will not only enlighten you on how people behave but also allowing you to act on them.

The full details of the study are published in Scientific Reports journal. The next time you feel guilty because you already had four cups and still counting, take it easy on yourself and simply blame it on your genes. Just remember the golden rule – too much of something is bad enough.
