Genetic variation means some don’t need as much coffee to get a kick
Change in the PDSS2 gene makes it harder for body to metabolise caffeine
People without the variation process caffeine faster and so drink more

our desire to grab coffee from Starbucks could be written in your genes, scientists claim.
New research has found people with a certain variation of a gene don’t need to consume as much coffee to get a caffeine hit – quelling their urge for more.
The gene in question is called PDSS2 – and the variation reduces the body’s ability to break down caffeine – causing it stay in a person’s system for longer.
Those without the variation metabolise caffeine more quickly and as a result, are more likely to have an extra cup each day.
Go Sook! Yum yum. Almost time for hot coffee again.
