Coffee Addiction – It May Be In Your DNA
Are you grabbing your fifth cup of coffee of the day and it's not even noon yet? Is the grande still not big enough? A new study says there might be an answer for that.
I grew up with both my parents smoking and drinking coffee at the same time. It was a ritual in our house. To be honest, I hated the smell of it! I've never smoked, but in my twenties, my french boyfriend George taught me to drink awesome coffee. He used a french press and a dash of heavy cream, and it was heavenly. He also smoked like a fiend, but I loved him in a different way then my folks, so somehow the smell never bothered me. You know what I mean ;)
But the answer for your need for more coffee could lie in your DNA. A new study published in Science Daily says that people with a DNA variation, in a gene called PDSS2, tend to drink fewer cups of coffee. According to the study this gene reduces the ability of cells to break down the caffeine and that in turn makes it stay in a persons body longer.
All of that translates to people with this DNA variation not needing to drink as much coffee to get the same caffeine jolt the rest of us do.
Dr Nicola Pirastu had this to say to sciencedaily.com
The results of our study add to existing research suggesting that our drive to drink coffee may be embedded in our genes. We need to do larger studies to confirm the discovery and also to clarify the biological link between PDSS2 and coffee consumption
So as you grab your extra cup of coffee, feel free to blame your parents for not giving you the weirdo DNA variation that causes you NOT to need as much caffeine, hence causing your coffee addiction! Since I'm adopted that ship has sailed, so I think I'll happily get a Mocha Latte Grande and smile over my memories of George.
