It seems as if your caffeine fix may have a lot to do with your genetic inheritance.
There are many who cannot leave their beds in the morning without “waking up and smelling the coffee”. Literally, such an addictive state is a real-life occurrence for many folks who just feel too groggy and have plenty of brain fog until they consume one or two cups of java. Yet this is something for which these coffee freaks ought not to be blamed. It is in their genes to do such a compulsive imbibing act.
Scientists have discovered that a gene termed PDSS2, that plays a key role in the breakdown of caffeine in the bloodstream, is responsible for this behavior.
Thus by switching this gene off, caffeine addiction may be kissed goodbye forever. In actuality, many genes go on to play a vital function as far as coffee addiction is concerned.
A variant of the gene discussed a few lines back is responsible for slowing down caffeine digestion thus making it remain in the body for a longer period of time. What this means on an everyday level is that you wouldn’t need too many cups to get through the day without having fits of narcolepsy.
Thus now we know why some people just need one cup of coffee to make it to the office on time while others need two or three to even open their eyelids.
The addiction finds expression at the genetic level. The study looked into the cases of two groups of people. One of them was in Italy and the other one was in the Netherlands.
The latter group showed less of an expression of the PDSS2 gene. This may be due to the differences of types of coffee found in both nations.
Thus what this definitely proves is that our coffee fix may be inherited. More studies need to be conducted before we can say with any assurance what coffee consumption is tied up with.
It could be the genes or the environment or a mixture of the two. The third option is the more realistic one of the three scenarios.
Meanwhile, all the coffee freaks in the world can go ahead and get their favorite recreational perk in the form of a hot steaming cup of java. It won’t hurt them as much as some other hard drugs. They can of course blame it on their mama and papa since that is where their genes came from.
