The findings, likely, won't have much of an impact on most of us in the U.S. - the average American drinks 1.6 cups a day (compared to eight in Finland, the coffee capital of the world, according to the International Coffee Organization).
Having set out to uncover the relation between long-term coffee consumption and heart disease and to explore the potentials of the caffeine-metabolizing gene, the researchers made quite interesting findings. The World Health Organization calls cardiovascular disease the leading cause of death as well as one of the most preventable causes of death.More news: Brexit rebels tell Theresa May - Your EU divorce deal is dead
This isn't the first time we've been celebrating a potential link between coffee consumption and life expectancy.
Previous studies have found multiple other benefits of drinking coffee, including reducing the risk of Alzheimer's and Parkinson's disease. In fact, the researchers also found that participants who didn't drink coffee at all-and those who drank decaf-also had higher rates of heart disease (11% and 7% higher, respectively) than those who drank one to two cups per day. They explain that research shows that excess coffee can harm the heart by raising blood pressure.
The findings come from the analysis of data from the UK Biobank that included 347,077 participants aged 37 to 73 years old.
And they identified which coffee consumption habits increased or lowered the risk of cardiovascular disease.More news: US Treasury Chief to Plan for Trade Meeting in China Soon

"Most people would agree that if you drink a lot of coffee, you might feel jittery, irritable or perhaps even nauseas - that's because caffeine helps your body work faster and harder, but it is also likely to suggest that you may have reached your limit for the time being".
"An estimated three billion cups of coffee are enjoyed every day around the world", Prof Hyppönen says.
And it's good news if you are something of a caffeine fiend, as two cups per day could actually be helping you to live longer, according to new research.More news: Saudi pumping stations struck by drones carrying explosives, says minister
