Yes, you do need that coffee!

There are all kinds of studies touting the health benefits of coffee, but a new one suggests that the need you feel for coffee every morning, and possibly again in the afternoon, is not only real, it’s genetic.

According to a study is published in the journal PLoS Genetics, researches have found two stretches of DNA associated with high consumption of caffeine:

Study author Dr Neil Caporaso of the National Cancer Institute, Bethesda, Maryland, US, said people with the high consumption genetic variation consume more caffeine – about 40mg – or a third of a cup of coffee or a can of cola – than other individuals.

He told the BBC: “There are hundreds of genes known for specific medical conditions – for dietary consumption we know very little.

“Now, for the first time, we know specific genes that influence the amount of caffeine that individuals consume.”

So, next time someone tells you you don’t need that extra cup of coffee, you can say, “Yes. Yes, I do!”
