There’s some news that you just don’t want to read in the morning. A new study shows that people who drink a lot of coffee may have a higher mortality rate.
Yep, you may want to put that cup of joe down before you continue reading this article.
A new study published in the journal Mayo Clinic Proceedings claims that people who drink about four cups of coffee per day have an increased risk of dying early.
The study looked at more than 40,000 men and women between the ages of 20 and 87 and found that people who drink a lot of coffee (more than 28 cups per week) had a 21 percent higher mortality rate.
Younger men and women (below the age of 55) had a 50% higher risk of dying.
The study, which used data from the last three decades, was conducted by Steven Blair and his team at the University of South Carolina.
Xuemei Sui, a co-author on the study, said that coffee may be linked to a higher mortality rate but that the research team still wasn’t sure why.
Sui told The Guardian: “The exact mechanism between coffee and mortality still needs clarification. Coffee is high in caffeine, which has the potential to stimulate the release of epinephrine, inhibit insulin activity, and increase blood pressure.”
Sui also noted that coffee’s mortality rate may reflect other factors like smoking or drinking alcohol. Sui said that younger coffee drinkers, who had a higher mortality rate, may also have other unhealthy behaviors.
Sui said: “Heavy coffee consumption behavior might cluster with other unhealthy behaviors such as sleeping late, and eating a poor diet.”
The new study may link coffee to a higher mortality rate but it isn’t the definitive word on the subject. Coffee has many health benefits. One recent study showed that coffee helped with depression and led to a lower suicide rate.
