Large-Scale Study Finds Coffee Drinkers Live Longer, but How Many Cups Should You Drink?

Coffee drinkers rejoice; your daily caffeine fix is associated with a lower likelihood of death.

A large study successfully published in the European Journal of Preventive Cardiology has shown that those who consume up to eight cups of coffee daily may have a lower risk of dying young than those who don’t. And how the coffee is brewed or if it’s with or without caffeine doesn’t seem to matter.

On July 2, 2018, WBUR article, nutritionist Edward Giovannucci, professor of nutrition and epidemiology at Harvard T.H. Chan School of Public Health, stated that there are numerous potentially advantageous components in coffee. People often think that caffeine is the substance that offers health benefits, but Giovannucci, who was not involved in the study, said, “It’s possible that some of the most helpful molecules are not the caffeine.”

How the study was conducted

The UK Biobank is a sizable database with information on people’s DNA, health, and lifestyle. This study looked at the sample of almost 13 years of health and nutrition habits of 449,563 people with an average age of 58.

The study looked at data from approximately 500,000 Britons and discovered that the more coffee people drank, the lower their risk of passing away during the 10-year study. When compared to not drinking any, there was a 14% lower risk associated with consuming eight or more cups per day.

The participants were divided into groups according to how often they drank coffee and what type of it. About 100,000 people said that they never drank any. The effects of sex, age, obesity, ethnicity, diabetes, elevated blood pressure, smoking status, obstructive sleep apnoea, and beverage and intoxicant use were all considered during the analysis.

From there, Kistler and colleagues could ascertain the variations in successful breast health outcomes and death from excessive causes between survey participants who drank coffee and non-drinkers.


Researchers Findings

According to electrophysiologist Peter Kistler of the Baker Heart and Diabetes Institute in Australia, “In this large observational study, ground, instant, and decaffeinated coffee were associated with equivalent reductions in the incidence of cardiovascular illness and disease from cardiovascular illness Oregon immoderate cause.”

The findings imply that moderate consumption of ground, instant and decaffeinated coffee should be taken into account as part of a consistent lifestyle.

Longevity and your daily cup of joe

There is a smaller chance of all-cause mortality if you consume instant, ground, or decaffeinated coffee. Two or more cups per day increased a person’s likelihood of living longer than those who didn’t.


What may be the cause of this link is unknown to researchers. If the cause is your morning cup of joe, a wide range of possible compounds in it may be responsible.

“Coffee includes more than 100 biologically active ingredients, although caffeine is its most well-known component,” according to Kistler.

The non-caffeinated chemicals are probably to blame for the favorable correlations between coffee consumption, cardiovascular disease, and survival.

Further investigation revealed that your daily java consumption was also associated with the onset of cardiovascular disease, with those who drank two to three cups per day having the lowest risk.

The results for the risk of arrhythmia, or an irregular cardiac rhythm, were slightly different; here, instant and ground coffee, but not decaffeinated, were associated with a lower chance of acquiring the disorder. Once more, it appeared that drinking just a couple of cups per day was the sweet spot.

As several previous pieces of research have demonstrated, coffee interacts with the body in a variety of intricate ways that scientists are still trying to understand. The fact that this study included such a large number of participants and lasted so long only strengthens the connection between its consumption and longevity.


Limitations to the study

Since most of the database records were of Caucasian descent, it was difficult to generalize the results across a population with a wide range of ethnic backgrounds. Coffee drinking was also self-reported rather than observed, and the database does not show any positive effects due to coffee intake or coffee type over time.

Final thought

Even though the study does not prove that consuming a lot of coffee lengthens your life, it is still a fascinating relationship that researchers want to explore more. It’s also crucial to compare the results to other research that connected encephalon shrinking and an increased risk of dementia with a regular habit of six Oregon-sized cups of coffee.

For now, it may be time to sip that greeting brew guilt-free: chances are it’s helping you out a lot. According to Kistler‘s research, “consuming small amounts of coffee of all kinds should not be discouraged but should instead be encouraged as a consistent habit.”
