A new study suggests that the genetic traits of coffee consumption are linked to obesity and drug abuse has been published in Neuropsychopharmacology. Globally, coffee is one of the most commonly consumed beverages, and caffeine is the most widely consumed psychoactive substance.
According to previous studies, moderate caffeine intake is known to be associated with a reduced risk of liver disease, cardiovascular disease, certain cancers, and neurodegenerative diseases. On the other hand, some studies suggest that caffeine intake may be interrelated with the misuse of different drugs and a few types of cancers, and other research has shown that genetic factors, alcohol consumption, and other environmental factors interact intricately.
Recent research indicates that genetic factors may significantly influence an individual’s coffee consumption habits. In a study involving twins, researchers discovered that the traits influencing caffeine consumption are approximately 36-58% hereditary. In the new study, researchers analyzed genetic data from two large-scale studies conducted in the United States and the United Kingdom.
The researchers investigated coffee consumption through a questionnaire and genetic data and distinguished between coffee containing caffeine and coffee without.
As a result of the study, the researchers reported that they were able to find the influence of genetic factors on coffee consumption in both datasets.
The researchers identified specific genes that influence how quickly the body processes caffeine and also pointed out the connection between coffee consumption and obesity. However, they clarified that this does not mean that coffee consumption promotes obesity but that the individual genetic differences that affect coffee consumption also influence obesity.
