"As a coffee drinker myself, they do reassure me that my habit probably isn't bad for me", he said.
The researchers said they made a "statistically significant" observation between those who consumed the most coffee and lower risk of death, compared to non-drinkers.
In the largest analysis of its kind, scientists looked at data from more than 500,000 people in 10 European countries, including the United Kingdom, to explore the effect of coffee consumption on the risk of death.
Drinking around three cups of coffee a day has been linked to a lower risk of death "from any cause" in two new large-scale studies.
The European study presented an inverse relation between coffee and circulatory diseases, digestive diseases, cancer in women, suicide in men, and liver disease.
But what really marks this coffee study apart from so many before it, according to USC researchers, is the inclusion of study participants from a more ethnically and racially diverse range of backgrounds than those in previous studies.
The second study found that higher coffee consumption was associated with lower risk for death in whites and also in non-white populations and that the mortality benefit was the same for caffeinated and decaffeinated coffee.
"We found that coffee drinkers had a reduced risk of death from heart disease, from cancer, from stroke, respiratory disease, diabetes and kidney disease", stated Veronica Setiawan.

Spooked by the wave of supply coming from multiple sources, many Wall Street analysts have grown bearish on the energy sector. That said, there's always a more optimistic case to be made, if only for purposes of playing devil's advocate.

Onus on Russian Federation to end Ukraine war, says U.S. secretary of state
In that role, Volker will lead US efforts to implement the 2015 Minsk agreement aimed at halting the fighting in Ukraine's eastern Donbass region.
People who had two to four cups a day had an 18 percent lower risk of death, in contrast with people who did not drink coffee at all.
"We can not say drinking coffee will prolong your life, but we see an association", said lead author Veronica Setiawan, an associate professor of preventive medicine at the Keck School of Medicine of University of Southern California. For instance, the study did not include factors like how much coffee drinkers earned compared to non-coffee drinkers. But an editorial accompanying the studies cited several potential reasons for dodging early death, such as the polyphenols in coffee that act as antioxidants and help cells fight free radicals.
Experts believe the antioxidant plant compounds in coffee - rather than the caffeine - are responsible for the life-extending effect.
While researchers are hesitant to say that everyone should start downing Starbucks, stat, they are willing to conclude that coffee is safe to drink, and could potentially be beneficial.
"I always felt its one of the few things that I enjoy that doesn't have calories", she said.
Coffee is one of the world's most popular drinks. Women who drank the same had a 7 per cent reduced risk. Scientists have found that people who drink coffee live a long life. However, it must be kept in mind that the recommended amount of coffee consumption by an adult must not exceed 400mg in a day. Two to three cups increased this to 18 percent.
90 percent of us all drink coffee every day and approximately 2.25 billion cups of coffee are drunk every day worldwide.
