This finding have surfaced ages ago about the health effects of coffee. A study has surveyed over 520,000 people in 10 different European countries. It’s a very large, could possibly be the largest study on coffee about finding out that drinking coffee could significantly lower someone’s risk of mortality.
The second study, focused in African-Americans citizen over 185,000 people including Native Americans, Hawaiians, Japanese Americans, and Latinos. The researchers found that coffee could increase the longevity depending on the races.
If people drink about two to four cups in a day, they’re likely to lower risk of death by 18% compared with people who didn’t have coffee. This finding is also said to be consistent with previous studies that looked the majority of white populations, told the associate professor of preventative medicine at USC’s Keck School of Medicine, Veronica Wendy Setiawan. She also told that given these diverse populations, all people have different lifestyles and very different dietary habits, also different susceptibilities, so a similar pattern has to be found.
A strong factor of biological possibility also play a role for the relationship between coffee, longevity and that mortality was inversely related to consuming coffee. This includes heart disease, cancer, respiratory disease, stroke, diabetes and kidney disease. The study that was conducted on European countries has linked coffee and liver disease, suicide in men, cancer in women, circulatory disease and digestive disease. Those who consume coffee more than three cups have the chance to lower those risks than the ones who didn’t.
Marc Gunter, a reader in cancer epidemiology and prevention at Imperial College’s School of Public Health UK told that the team have looked at multiple countries in Europe, where the way they drink coffee and prepare coffee is different. However, the fact that the team had seen same relationships in different countries. It’s the implication that the coffee itself is something. Rather than how they prepare it.
Coffee is a mix of compounds and has biological effects according to laboratories research. Some compounds have neuroprotective and anti inflammatory that can lessen the risk of illness, such as parkinson disease. In the European studies, people who consume coffee tend to lower the risk of inflammation, healthier and have better glucose control than those who don’t have coffee. However, it’s unclear which compounds in coffee that could provide all these health benefits. The researches are intended to explore this further tho!
There are more to note, both studies separate smokers and nonsmokers. Since we all know smoking could increase the risk of death, reduce the lifespan and connected to a lot of diseases. However, they found coffee had inverse effects on mortality for smokers included. Gunter told that smoking doesn’t seem to have an effect and there is a potential benefit of coffee on mortality.
“People should be wary of this finding.” said Dr. Alberto Ascherio, professor of Epidemiology and Nutrition at Harvard T.H. Chan School of Public Health.
“Even if it was in some way true, it doesn’t make sense to me, because by smoking, you increase your mortality several-fold. Then, if you reduce it by 10% drinking coffee, give me a break,” said Ascherio, a truly non involved person in this study. “I think it’s a dangerous proposition because it suggests that a smoker can counteract the effects of smoking by drinking coffee, which is borderline insane.”
The study is very complimentary and reasonable documented that coffee drinkers have a lower risk of death with all observations from previous studies, even though it’s difficult to exclude the possibility that coffee drinkers are healthier in the first place.
Places like US and Europe, where drinking coffee is very common or some may actually avoid it, may do so because they have health issues. They automatically have higher mortality rate from being less healthy.
“I think that the solid conclusion is that if you’re a coffee drinker, keep drinking your coffee and be happy,” Ascherio said. What if you’re not? “I think you can go on drinking your tea or water without a problem.”
On the other hand, Setiawan and Gunter are more into coffee as a health benefit. “The takeaway message would be that drinking a couple cups of coffee a day doesn’t do you any harm, and actually, it might be doing you some good,” he said. “Moderate coffee consumption can be incorporated into a healthy diet and lifestyle,” Setiawan said. “This studies and the previous studies suggest that for a majority of people, there’s no long term harm from drinking coffee.”
