Coffee’s Impact a Matter of Genes?

Coffee’s Impact a Matter of Genes?

Finally, the long day is over. It is time to hit the sack. But then here you are, tossing and turning and sleep just seem to be as elusive. Alas, you drank a cup of coffee during your afternoon break and now your body system is still taken over by the caffeine you have consumed. And now, you are stuck in your bed, mentally counting the hours until your alarm kicks in for another long day. By the way, your husband beside you is snoring – and he just had a cup of coffee before he went and go to bed.

Ever wonder why there are some people who seem to be able to enjoy a “heavenly” cup of coffee at any time of the day, even before going to bed and still sleep soundly while others cannot?

A new research might just be able to give the best answer for you. It is not about your age, gender or profession – you can actually blame it to nothing else but the genes.

According to this research primarily conducted by Marilyn Cornelis, “Each of us could be potentially responding to caffeine differently, and it’s possible that those differences can extend beyond that of caffeine.” Marilyn Cornelis works as an assistant professor in the Department of Preventive Medicine at the Northwestern University Feinberg School of Medicine in Chicago.

During the earlier stage of her research, Marilyn Cornelis has initially linked people’spatterns of coffee intake to the differences in their genetical patterns.

And, now in her newest research, Cornelis searched for the link between the variations in the genetic patterns and the traces of chemicals that show in the blood of the people after coffee consumption.

It was unraveled that there is a established connection between the patterns of the genes and the levels of caffeine chemicals that retain in people’s blood after their coffee intake. This suggested that some people may have faster caffeine metabolism rate compared to others. These are the same gene variations that were also attributed to have a relationshipas to why some people tend to have higher levels of coffee intake.

In addition, the team have uncovered an interesting finding – the genetic pattern may be also related to both the caffeine metabolism rate as well as the lipids and glucose rate of metabolism.

During an interview, Cornelis has said that, “How this gene relates to both caffeine metabolism and caffeine-seeking behavior is unclear but worthy of further study, given its link to several health outcomes.” She went on further stating that, “the study further re-emphasizes the notion that not everyone responds to a single cup of coffee or other caffeinated beverage in the same way.”

The said study was just recently published in the journal which is entitled “Human Molecular Genetics”. The research involved 10,000 European participants. Samples were taken from the said participants to experiment on the link between variations in their genes and the associated level of caffeine chemicals that will appear in their blood after their coffee consumption.
