Coffee Drinking in Your Genes? Genetic Variants in Two Genes Linked With Caffeine Intake

It has been discovered that the need to drink coffee is actually in our genes. A team of scientist from the national cancer institute, Harvard school of public health and university of North Carolina examined 47,000 individuals. They looked at the genetic variations’ across the entire genome and discovered that two genes affect the intake of caffeine which was CYP1A2 and AHR. The individuals that had the highest-consumption genotype for both genes consumed 40 mg more caffeine than the individuals with lower consumption genotypes. Not only does it affect the amount of caffeine that a person intakes it can lead to specific physiological and medical disorders, by changing moods physical performance and sleep patterns. They concluded that more test similar to this genome-based strategy could show more behavior and dietary determinates in our genes. It is a discovery based science because the researchers were simply studying the human genome and discovered this connection. It is import because the more we understand the human genome the easier it will be easier to discovered cures for diseases such as cancer diabetes. THE END
