Coffee Drinking Habits Can Be Written In Our DNA

Everybody loves coffee. It’s the perfect start for a hectic day and can wake you up from a state of sluggishness. You feel adrenaline rushing in your spirit, the moment you take a sip of hot coffee and as the aroma reaches your nostrils, you look forward to the day. You may like to start off by one cup or two cups of the holy drink and this actually depends on your genes because researchers have found a gene that appears to subdue coffee consumption.

A study conducted by Dr. Nicola Pirastu at the University of Edinburg found that a variation in a gene called PDSS2 determines the amount of coffee we drink. This finding suggests that variation in the PDSS2 gene is responsible for breakdown of caffeine by the cells, controlling its metabolism in the body.
This means that the effect of caffeine in blood differs between you and someone else.

A survey was completed with nearly 3000 people in various places in Italy and Netherlands, and each participant was asked about how many cups of coffee they drank on a daily basis.

It was found that people with DNA variations in gene PDSS2 tend to consume lesser cups of coffee than people who did not have the variation.

In Italy, people drink smaller cups of coffee whereas the Dutch prefer larger cups that contain more caffeine overall. Therefore, in Netherlands the effect of the gene was lower on the amount of coffee consumed.

Dr Nicola Pirastu says 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.”

These results are an addition to previous studies that link our coffee habits with our genes and edifies on how our body handles caffeine.

Coffee is the most consumed beverage in the United States after water and is the major source of caffeine in people. It contains a plethora of biologically active compounds with extensive health benefits.
Coffee reduces the risk of type 2 diabetes, Parkinson’s disease, dementia and a few types of cancer.

People who drink coffee are also generally healthier and at a reduced risk of mortality. Daily intake of 2-3 cups of coffee is considered healthy.

Other benefits coffee lovers enjoy are protection against asthma, neurological and gastrointestinal problems.

However, you need to be careful with all that caffeine because excess consumption of coffee can cause insomnia, continence, heart disease and osteoporosis.
