How Much Coffee You Drink May Be Genetically Determined

Coffee consumption may be in the genes. According to Science News, researchers say in the August 25th edition of Scientific Reports that activity of a gene that lowers levels of caffeine-degrading enzymes in the liver is associated with how much coffee people drink. The more active the gene, called PDSS2, the less coffee people drank. Researchers tracked the coffee-drinking habits of people in remote Italian villages and people from the Netherlands. The researchers looked for an association between drinking coffee and people’s genetic makeup. On average, the Dutch drank more than five cups of filtered coffee per day. But Italians sipped only about two cups of espresso. Nicola Pirastu, of the University of Edinburgh, and his colleagues found that in the Italians, 21 genetic variants in DNA surrounding the PDSS2 gene were linked to coffee consumption. https://www.sciencenews.org/article/thank-or-blame-your-genes-ability-handle-java-jolt http://www.wochit.com This video was produced by YT Wochit News using http://wochit.com
