The researchers identified the half a million participants through the United Kingdom biobank, an initiative to enroll approximately 9.2 million people, with long-term follow-up, and create a large database of individual, genetic sequencing to further understand the role of DNA on disease and treatment.
This population-based study including people ages 38 to 73 draws an association between coffee and health, meaning coffee might not be the cause of longevity.
The study also found that it did not matter what kind of coffee people drank, and how much. About one-third of those surveyed said they drank between two and three cups of coffee each day, and 10,000 of them drank eight or more cups each day. Simply drinking coffee isn't necessarily a health panacea. Drinking coffee is associated with a lower risk of early death - virtually regardless of how much you drink and whether or not it's caffeinated, concludes a paper published Monday in JAMA Internal Medicine.
Coffee contains more than 1,000 compounds that might explain the results, including cell-protecting antioxidants.
According to him, coffee got a bad reputation because in the past, many of those who enjoyed their brew also tended to smoke cigarettes.
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. The authors called for future studies with more detailed data collection on coffee type and preparation to provide further insights. This included ground coffee, instant coffee as well as decaffeinated coffee. This adds to a significant body of research indicating that coffee has positive effects on the heart, liver, brain, and more. He drinks about three cups a day. These people are known as slow metabolizers of coffee. So the next time someone says they're trying to limit their coffee consumption, you can tell them not to worry about it. Differences by amount of coffee consumed and genetic variations were minimal.
No doubt more coffee studies will be along in the very near future.
Previous studies have found coffee drinkers have a 15 percentlower risk of death and are less likely to die from respiratory disease, stroke, injuries and accidents, diabetes, and cardiovascular disease. For the current study, the researchers analyzed information provided by about 500,000 people, who answered questions about their coffee consumption, smoking and drinking habits, health history and more. Researchers noticed an inverse association between drinking coffee and the risk of death, regardless of whether individuals metabolized it quickly or slowly.
