PhotoSome people avoid it and some people can’t get through a morning without it, but a new study shows that drinking coffee helps consumers live longer and healthier lives.

Researchers from the University of Southern California’s (USC) Keck School of Medicine have found that those who drink just one cup of coffee per day lower their risk of death due to heart disease, cancer, stroke, diabetes, and respiratory and kidney disease by 12%. Those who drink 2-3 cups per day reap even greater benefits, with an 18% reduced risk of death.

While the researchers admit that their study does not prove causation (i.e. that drinking coffee is the thing that reduces risk of death) they say that there is a definite association.

“If you like to drink coffee, drink up! If you’re not a coffee drinker, then you need to consider if you should start,” said lead author Veronica W. Setiawan.

Lower mortality rates

The researchers analyzed data on nearly 186,000 people across multiple ethnicities to come to their conclusions. Participants were asked to answer questionnaires about their diet, lifestyle, family and personal medical history, and their coffee drinking habits.

Respondents were asked to check one of nine boxes describing how much coffee they consumed, ranging from “never or hardly ever” to “4 or more cups daily.” They also denoted if the coffee they drank was caffeinated or decaffeinated.

Over a period of 16 years, with updates being recorded every five years, approximately 31% of the participants in the study passed away, but the researchers found that those who drank more coffee had lower mortality rates than their peers.

Americans drinking up

But what is it about coffee that leads to this longevity? The researchers found that whether or not the coffee was caffeinated didn’t really matter, but they theorize that other ingredients play an important role.

“Coffee contains a lot of antioxidants and phenolic compounds that play an important role in cancer prevention,” said Setiawan. “Although this study does not show causation or point to what chemicals in coffee may have this ‘elixir effect,’ it is clear that coffee can be incorporated into a healthy diet and lifestyle.”

Luckily, it may not take much to convince consumers to start drinking coffee. Data from the National Coffee Association shows that 62% of Americans regularly drink coffee, a 5% increase from last year’s numbers.
