Addiction to coffee has a genetic cause.
The decomposition process of drinking coffee is determined by your genes, according to the Erasmus University in Rotterdam amongst 18.000 people.
Coffee is regarded by the liver as a potentially toxic foreign substance. The liver will make several proteins, after drinking a cup of coffee, to process the caffeine and more.
The genes will then determine whether the liver can handle the conversion of caffeine.
The study also shows that drinking coffee can affect diseases such as hypertension and Parkinson’s disease. It appears that people with Parkinson’s disease drink less coffee.
The research is published in the scientific journal “Molecular Psychiatry”.
American research at the universities of Harvard and North Carolina showed previously that the desire for coffee in located in genes.
According to the researchers, participants with a particular genetic variant on average consume 40 more milligrams of caffeine per day than people with a genetic variant of a low caffeine use. An amount of 40 milligrams is equivalent to one glass of cola or a butt of coffee.
