Your coffee addiction might be your body's way of telling you the secret to a long life: Drinking three cups a day might give you an advantage over people who don't drink a good brew. Drinking two to three cups of coffee reduced the chances of death by 18 per cent.
The findings have reignited the centuries-old conversation on coffee's health effects.
However, this isn't the first research to indicate that coffee may improve your health. So, this is the solid reason to start the day with a strong cup of coffee.
The researchers noted that the results were the same whether participants drank caffeinated or decaffeinated coffee, which implies that caffeine is not responsible for the decreased risk of death. They filled in questionnaires regarding their lifestyle and diets, including coffee consumption.
Dr. Veronica Wendy Setiawan is the lead author of the study and an associate professor of preventive medicine at the Keck School of Medicine of USC. For instance, the study did not include factors like how much coffee drinkers earned compared to non-coffee drinkers. Among that group, men were 12% less likely to die early than comparable people who avoided coffee completely.
It turned out that coffee drinkers had somewhat better survival odds. It did its research on 185,000 whites, Latinos, Japanese-Americans, Hawaiians, Native Americans, and African-Americans.
And as a trio of Johns Hopkins University scientists wrote in an editorial accompanying the two papers, "a protective effect of coffee is biologically plausible".
Apparently, coffee reduces the risk of death due to heart disease, cancer, stroke, diabetes, respiratory disease, and kidney disease.
The second study included over 450,000 participants from European countries. During the investigation, almost 42,000 died.
The study revealed that people of all races benefited from drinking coffee as those who consumed it had an 18% lower risk of death.
Despite the people being so different from country to country, the researchers saw a consistent relationship, said co-lead author Neil Murphy, of the Inter Agency for Research on Cancer in Lyon, France. The studies were published on Monday in the Annals of Internal Medicine.
Scientists have found that people who drink coffee live a long life.
The results don't necessarily mean coffee directly prevents people from dying, but researchers suggest they should at least reassure people who can't get by without their daily cup of joe. And some people, such as pregnant women and teenagers, should have stricter caffeine limits. Coffee does contain many bioactive chemicals, including those with antioxidant effects, which have been shown in the past to have positive impacts on health.
NHS experts have not set limits for coffee in the general population but they do say that pregnant women should avoid drinking more than 200mg of caffeine a day.
