Yes, Some People May Need Coffee

If you like coffee, chances are you don’t settle for just one cup in the morning. Researchers now think they understand the grip coffee has over many of us a little better. It seems our addiction to coffee may be in our genes.

Scientists have discovered genetic mutations in a gene called PDSS2 that correspond closely to how much coffee a person drinks. They believe the gene plays a role in how quickly the body breaks down caffeine.

A recent study looked at participants’ genetic patterns and rates of coffee consumption, which ranged from 2 or 3 cups a day to more than 6 cups. Study participants were from Italy and the Netherlands. According to researchers, people who had a recessive form of the gene drank less coffee than those without the particular mutation of the gene.
