Large study shows drinking coffee could extend your life

The difference was around eight per cent to 16 per cent for coffee drinkers being less likely to die, with how many cups were consumed per day having little variation on the life boosting benefit.

The researchers used data from the UK Biobank study, through which a large group of UK adults completed health questionnaires, underwent physical examinations and provided biological samples. It does however provide further evidence that coffee drinking can be part of a healthy diet and offers reassurance to coffee drinkers. Among at least the generally healthy individuals from the United Kingdom enrolled in this study, coffee drinkers seem to gain health benefits from the habit. The researchers were then able to correlate the rates of death with the amount of coffee that each cohort described drinking each day.

"Coffee drinkers, compared with non-coffee drinkers, were more likely to be male, white, former smokers, and drink alcohol", the study found.

Previous studies in the US, Europe and Asia have found a consistent link between coffee drinking and reduced deaths from all causes including diabetes, cardiovascular disease, Parkinson's disease and liver, bowel and womb cancer.

Coffee contains more than 1,000 biological compounds, including potassium and folic acid, known to have an effect on the body, Loftfield explained.

That finding, combined with the apparent longevity-boosting effect of decaf coffee, suggests that caffeine isn't the life-lengthening mechanism at work in java, Loftfield said. The study results showed coffee drinkers had a lower risk of death overall, just as many other studies have found.

Following Chestnut, Carmen Cincotti shoved 63 hot dogs down his gullet, and Matt Stonie managed to devour 43 dogs. The 35-year-old Baton Rouge native won a spot in the contest after qualifying in Houston by eating 39 hot dogs.

The study was published on Monday in the journal Jama Internal Medicine. But it turns out that even slow caffeine metabolizers seem to share the death-risk-reduction connected to coffee drinking. It covered almost half a million people, for a start, which is definitely to its credit. However, he highlighted the findings could be at risk of inaccuracies due to unknown or unmeasured factors linking to drinking coffee and being in good health. And it also doesn't matter what version of the "coffee gene" people have.

According to him, coffee got a bad reputation because in the past, many of those who enjoyed their brew also tended to smoke cigarettes. Instead, it could be one or a combination of several of the hundreds of chemicals that make up coffee.

But, "drinking coffee is not a miracle in a cup, and is unlikely to prevent the consequences of an unhealthy lifestyle, such as the typical Western diet or smoking tobacco", Heller noted.

Years ago, health concerns about coffee included fears that it might raise risk of pancreatic cancer and other diseases.

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