Drinking coffee may make people live longer

Drinking coffee every day is linked to a variety of health benefits, including the possibility that you will live longer, according to research. Does this benefit have anything to do with caffeine?

The study, published Monday in the journal JAMA Internal Medicine, involved about 500000 people aged between 38 and 73 in England, Scotland and Wales. 

Erikka Loftfield, a researcher at the National Cancer Institute, said the 10-year study found that people who drank 2-3 cups of coffee a day were about 12 percent less likely to die than those who did not drink coffee at all. 

The findings apply to all coffee drinkers, including those with slow caffeine metabolism and those who drink decaffeinated coffee, the study said. 

“We have observed an inverse association between drinking coffee and mortality, including drinking drip filter coffee, instant coffee and decaffeinated coffee, whether they drink at least one cup a day or more than eight times a day,” said Rofftefield. “We have seen a negative correlation between drinking coffee and mortality. This includes drinking drip coffee, instant coffee and decaffeinated coffee, whether they drink at least one cup a day or more.” ” 

The data were collected from the British Biological data Bank, which analyzed the coffee, smoking and drinking habits and medical history of the 500000 people. About 1, 4200 of the 500000 people died in the 10 years that the study was conducted. 

The study was conducted in the UK, but other previous studies in the US have found that in African-Americans, Japanese-Americans, Hispanics and whites, drinking more coffee is associated with a lower risk of early death, regardless of sex.The daily coffee drinking habit was also associated with a lower risk of stroke and type 2 diabetes. 

Is caffeine related to these health benefits? NPR points out that it may not matter. Several studies have not shown that drinking coffee leads to longevity, but several studies have found that people who drink regular and decaffeinated coffee are more likely to live longer than those who don’t. 

If not caffeine, why? The researchers turned their attention to the coffee beans. 

“Coffee beans themselves are full of many different nutrients and phytochemicals,” said Walter Willett, a nutritionist at Harvard School of Public Health in 2015, including lignans, magnesium and quinidine, some of which may help reduce insulin resistance and inflammation. 

“I guess these ingredients add up to some of the health benefits,” Willett said. ” 

Christopher Gardner, head of nutrition research at Stanford’s Center for Preventive Research, said: “Coffee is made up of thousands of chemicals, including polyphenols and antioxidants. ” 

Gardner says there is plenty of evidence to support the argument that coffee is a healthy diet, and that the 2015 U. S. dietary guidelines explicitly state that daily coffee consumption may help prevent type 2 diabetes and cardiovascular disease. 

Gardner says part of the benefit of coffee has to do with a simpler reason: making people happy. 

“think about it when you drink coffee,” Gardner said. “do you stop and relax a little bit when you’re drinking coffee? “with at least three cups of coffee a day, he thinks the answer is precisely that simple pleasure.
