Scientists have established that for the love of a specific person to a coffee meet not only its habits but also genetics. Special influenced by the presence of PDSS2 gene.
In the experiment, the researchers analyzed the genome of thousands of volunteers from Italy. It turned out that the absence of a gene PDSS2 significantly reduces the human attraction to drinks with caffeine. The gene is responsible for rapid breakdown of caffeine. As a result, people-carriers of PDSS2 longer feel full from the coffee.
Caffeine is a substance belonging to the group of Central nervous system stimulants. Like any other stimulant, this compound has an individual action depending on a particular person. Apparently, genes in the formation of Coffeemania are playing not the last role.
