Drinking more coffee can lead to a longer life

New York [USA]: Coffee lovers, rejoice! We have some happy news for you.

According to two new studies, greater consumption of of coffee could lead to a longer life, reports CNN.

One study surveyed more than 520,000 people in 10 European countries, making it the largest study to date on coffee and mortality, and found that drinking more coffee could significantly lower a person’s risk of mortality.

The second study focused on non-white populations. After surveying over 185,000 African-Americans, Native Americans, Hawaiians, Japanese-Americans, Latinos and whites, the researchers found that coffee increases longevity across various races.

People who drank two to four cups a day had an 18 percent lower risk of death compared with people who did not drink coffee.

These findings are consistent with previous studies that had looked at majority white populations, said Veronica Wendy Setiawan, associate professor of preventative medicine at USC’s Keck School of Medicine, who led the study on nonwhite populations.

He said, “Given these very diverse populations, all these people have different lifestyles. They have very different dietary habits and different susceptibilities — and we still find similar patterns.”

The new study shows that there is a stronger biological possibility for the relationship between coffee and longevity and found that mortality was inversely related to coffee consumption for heart disease, cancer, respiratory disease, stroke, diabetes and kidney disease.

The study on European countries revealed an inverse association between coffee and liver disease, suicide in men, cancer in women, digestive diseases and circulatory diseases.

Those who drank three or more cups a day had a lower risk for all-cause death than people who did not drink coffee.

We looked at multiple countries across Europe, where the way the population drinks coffee and prepares coffee is quite different,” said Marc Gunter, the study’s co-author.

Adding, “The fact that we saw the same relationships in different countries is kind of the implication that its something about coffee rather than its something about the way that coffee is prepared or the way it’s drunk.”

In the European study, people who were drinking coffee tended to have lower levels of inflammation, healthier lipid profiles and better glucose control compared with those who weren’t.

It is still unclear which particular compounds provide health benefits, but Gunter said he would be interested in exploring this further.

Both studies separated smokers from nonsmokers, since smoking is known to reduce lifespan and is linked to various deceases.

However, they found that coffee had inverse effects on mortality for smokers too.

“Smoking doesn’t seem to blunt the effects of coffee,” Gunter said. “It didn’t matter whether you smoked or not. There was still a potential beneficial affect of coffee on mortality.”

The studies complement work that has been done on coffee and mortality, he said, and it has been reasonably documented that coffee drinkers have a lower risk of death.

With all observations from previous studies, however, it’s difficult to exclude the possibility that coffee drinkers are just healthier to begin with, Gunter said.

People who avoid coffee, particularly in places like the US and Europe where drinking the beverage is very common, may do so because they have health problems.

Their higher mortality rate could be a result of them being less healthy to begin with.

Gunter concluded by saying, “The takeaway message would be that drinking a couple cups of coffee a day doesn’t do you any harm, and actually, it might be doing you some good.” (ANI)
