How much you drink is determined by your genes
–
The amount of coffee you drink has nothing to do with stereotypes or disciplines. It’s in your genes, research shows.
Statement
from the research shows that six new genetic variants have been found that are associated with the amount of coffee a person consumes. According to the researchers, these variants explain why some people need a lot of coffee and others start bouncing from just the smell.
Research
In the study, the researchers studied 2.5 million genetic variants, from more than 120,000 men and women. The analyzes of the genes were compared with the amount of coffee the participant drinks. This discovered that the differences in the habits correspond to the gene variants. It was already known that these genes are related to our response to caffeine. It turns out that some variants of these genes respond positively to the caffeine, as a kind of reward, while others don’t. In the latter group, the caffeine is processed more slowly or more quickly by the body, causing different reactions to coffee.
Next step
Yet not everything is said with this research: it only explains 1.3 percent of our coffee drinking behavior. This is about as much as genes say about habits like smoking and drinking. Culture would also have a major influence on the rate of coffee consumption. The study’s leader, Marilyn Cornelis, says these results are just the beginning. “The next step is to find out who benefits the most from coffee.”
