Your Preference for Coffee is in Your Genes

Coffee – After reading the article “Why Do I Like Coffee, But Not Tea? Science Says It May Come Down To Your Genetics” I now know part of what is in my genetic makeup – bitter taste receptor genes.

A study was undertaken at the University of Queensland in Australia to find out more about the genetic factor in the individual’s preference for coffee. The results of their study (“Understanding the role of bitter taste perception in coffee, tea and alcohol consumption through Mendelian randomization“) has been published in the journal Scientific Reports.

The study looked at 400,000 people in the UK between the ages of 37 and 73. It compared both their coffee/tea-drinking habits, along with data on their genetic makeup. They found that those who carry the “bitter taste receptor gene” are much more likely to drink large amounts of coffee. In fact, for each “extra copy” of that gene, the probability that the individual would be a coffee drinker went up by 20%.
