Go ahead and have that cup of coffee, maybe even several more. New research shows it may boost chances for a longer life, even for those who down at least eight cups daily.

In a study of nearly half-a-million British adults, coffee drinkers had a slightly lower risk of death over 10 years than abstainers.

The apparent longevity boost was seen with instant, ground and decaffeinated, results that echo U.S. research. It’s the first large study to suggest a benefit even in people with genetic glitches affecting how their bodies use caffeine.

Overall, coffee drinkers were about 10 percent to 15 percent less likely to die than abstainers during a decade of follow-up. Differences by amount of coffee consumed and genetic variations were minimal.

The results don’t prove your coffee pot is a fountain of youth nor are they a reason for abstainers to start drinking coffee, said Alice Lichtenstein, a Tufts University nutrition expert who was not involved in the research. But she said the results reinforce previous research and add additional reassurance for coffee drinkers.

“It’s hard to believe that something we enjoy so much could be good for us. Or at least not be bad,” Lichtenstein said.

The study was published Monday in the journal JAMA Internal Medicine.

It’s not clear exactly how drinking coffee might affect longevity. Lead author Erikka Loftfield, a researcher at the U.S. National Cancer Institute, said coffee contains more than 1,000 chemical compounds including antioxidants, which help protect cells from damage.

Other studies have suggested that substances in coffee may reduce inflammation and improve how the body uses insulin, which can reduce chances for developing diabetes. Loftfield said efforts to explain the potential longevity benefit are continuing.

“Coffee makes you happy, it gives you something to look forward to in the morning,” said Taylor, a sound engineer from Las Vegas.

“I try to have just one cup daily,” Taylor said. “Otherwise I get a little hyper.”

For the study, researchers invited 9 million British adults to take part; 498,134 women and men aged 40 to 69 agreed. The low participation rate means those involved may have been healthier than the general U.K. population, the researchers said.

Participants filled out questionnaires about daily coffee consumption, exercise and other habits, and received physical exams including blood tests. Most were coffee drinkers; 154,000 or almost one-third drank two to three cups daily and 10,000 drank at least eight cups daily.

During the next decade, 14,225 participants died, mostly of cancer or heart disease.

Caffeine can cause short-term increases in blood pressure, and some smaller studies have suggested that it might be linked with high blood pressure, especially in people with a genetic variation that causes them to metabolize caffeine slowly.

But coffee drinkers in the U.K. study didn’t have higher risks than nondrinkers of dying from heart disease and other blood pressure-related causes. And when all causes of death were combined, even slow caffeine metabolizers had a longevity boost.

As in previous studies, coffee drinkers were more likely than abstainers to drink alcohol and smoke, but the researchers took those factors into account, and coffee drinking seemed to cancel them out.

The research didn’t include whether participants drank coffee black or with cream and sugar. But Lichtenstein said loading coffee with extra fat and calories isn’t healthy. (VOA)

Genes of Your Uncle or Aunt May Decide Your Longevity, Says Study

The study has led us to be far stricter in selecting the people in whom you have to look for those genes, the researchers said

The key to longevity can probably be found in the genes of your long-living uncles and aunts and not just parents, finds a study.

Researchers, from Netherlands’ Leiden University and US’ University of Utah, showed that an individual’s chances of dying is reduced, even if the parents themselves did not live to be extremely old, but aunts and uncles are among the top survivors in the family.

Top survivors refers to people in the top 10 per cent age-wise of a group of people born in a family within a given time period.

“We observed the more long-lived relatives you have, the lower your hazard of dying at any point in life,” said lead author Niels van den Berg, doctoral student at Leiden University in the Netherlands.

“Longevity is heritable, but that primarily applies to persons from families where multiple members are among the top 10 per cent survivors of their birth cohort. The key to a long life can probably be found in the genes of these families,” said the paper published in the journal Nature Communications.

For the study, the team analysed the genealogies of nearly 314,819 people from over 20,360 families.

The search for genes associated with human longevity has been ongoing for a long time but those genes turned out to be much more difficult to discover than genes for diseases.

The study has led us to be far stricter in selecting the people in whom you have to look for those genes, the researchers said.

According to Ken Smith, Professor at Utah, the findings underscore the importance of constructing high-quality family trees that “allow us to observe complete life-spans of individuals over generations and in diverse locations. (IANS)
