Coffee as the ability to change your DNA

Researcher took their time to look into the favourite drink of most people, and they discovered that it could change the DNA in some ways.

Before Now, coffee has always been good for the health. Research shows that taking coffee could lead to low blood pressure, a sharp memory, better liver health, a better chance against developing dementia, and arguably it also leads to a longer lifespan.

Recently some scientists decided to study our favorite legal drug even more. They wanted to understand why coffee is linked to its health benefits. They centered their research on “epigenetic” changes.

Epigenetics Changes

“Epigenetics represents modifications to DNA that do not change the underlying DNA sequence, but instead, influence gene expression, Epigenetics is suggested as a mechanism mediating the effects of dietary and lifestyle factors on disease onset.” the researchers wrote in the study.

The study evaluated “epigenome-wide” association studies of coffee and tea consumption of nearly 15,800 people of European and African-American descent. To get to that number of people, they included results from 15 epigenetic studies, which collectively covered a lot of ground.

“The major strength of the present study is the large sample size and multi-ethnic contribution,” the researchers noted.

While looking for other factors that could influence our genes apart from coffee, the researchers homed in on epigenetic associations specific to drinking coffee and tea. They found a meaningful handful that is thought to decrease the risk of certain diseases, most importantly liver disease and heart disease.

DNA methylation is the process by which coffee compounds influence our genes. And the more this process is studied, the more it appears key to controlling epigenetic switches for a growing list of diseases and disorders.

“Collectively, this study indicates that coffee consumption is associated with differential DNA methylation levels…and that coffee-associated epigenetic variations may explain the mechanism of action of coffee consumption in conferring disease risk,” the researchers wrote.

This is actually not the first time, this sort of result was discovered. Before now, it was discovered that coffee may even “repair” broken DNA strands and reinforce whole strands against breakage, also through methylation. Which in turn may affect the expression of genes related to everything from Alzheimer’s to Type 2 diabetes to Parkinson’s disease.


Although this is good news, these discoveries are still preliminary and based on observing correlations between factors — not spot-on causation, but getting closer.

But it’s actually good to know that favorite legal drug has so many health benefits.
