People who drink coffee live longer, say studies

Wednesday, 12 Jul, 2017

It's your lucky day, coffee drinkers.

A second study in the same journal seemed to back up the claim.

The U.S. -based study found that drinking one cup of coffee daily seemingly lowered the risks of death by 12 percent, no matter the ethnicity.

They concluded this statement after analysing data from healthy people above the age of 35 from different European countries.

And heavy consumers of decaf or regular coffee - those who drink two to three cups each day - had an 18% reduced death toll from those illnesses. But it did reveal that coffee's benefits are consistent across all races.

Now, while this may sound like a glowing recommendation to ready the caffetiere or head to your nearest Starbucks, bear in mind that it's possible that people who drink three cups of coffee a day could also be doing other things that boost their health.

None of those studies prove coffee, per se, provides the benefit.

Both studies separated smokers from nonsmokers and other factors that could have played a part in the results.

Coffee is one of the most widespread drinks in the world.

People who drank three cups a day were, again, 18% less likely to die over that time period than those who had zero coffee. In every country, "coffee drinking was associated with reduced risk for death from various causes".

Prof. Naveed Sattar, professor of metabolic medicine at the University of Glasgow, said: "This is a very nice paper, but its conclusions will not lead me to recommend people drink more coffee as a way to lessen their risks for heart disease". It might actually be so good for you that it is actually extending your life by reducing risks from heart disease and even cancer.

Previous studies have shown conflicting and often contradictory results.

The researchers noted that their studies don't mean coffee itself prevents people from dying, as more research would be needed to make such a statement.

But caffeine affects some people more than others, and the effects can vary from person to person.

That said, he agreed with Setiawan's take: "We can reassure moderate coffee drinkers that they can continue", Guallar said. As doctors, we don't have to tell people to be anxious about drinking coffee anymore. These also found that the beneficial effects seemingly increase with each cup consumed. For example, the polyphenols found in coffee act as antioxidants, which helps cells survive from the damaging effects of molecules called free radicals.

Nearly 42,000 people died during the study period, of various causes: Roughly 18,000 from cancer; 9,100 from circulatory diseases like coronary artery disease; and 2,380 from cerebrovascular conditions like strokes, among other causes.

Professor Elio Riboli, head of the School of Public Health at Imperial College London said there are "lower markers of inflammation" and "better markers of liver function" with those who consume more coffee.

Besides asking participants about how much coffee they drank, a randomly selected group of 14,800 participants in the European study underwent a blood test at the beginning to analyze levels of biomarkers, which are substances linked to health.
