Health benefits: Can increased coffee consumption prevent premature death?


How does coffee affect life expectancy?

There are always statements about the effects of coffee on human health. However, some of the benefits of coffee consumption that have been identified in recent years remain controversial. Researchers have now found that drinking coffee is associated with a lower risk of premature death.

In their current study, scientists from the National Cancer Institute and the National Institutes of Health found that consuming coffee can protect people from premature death. The doctors published the results of their study in the English-language journal "JAMA Internal Medicine".

Is drinking seven cups of coffee a day healthy?

The results of the study show that drinking up to seven cups of coffee a day can reduce the mortality rate by 16 percent. Seven cups of coffee actually contain twice as much caffeine as the British Food Standards Agency recommends.

Data from almost 500,000 people was evaluated for the study

For the study, the team used data from the so-called UK biobank, in which around 500,000 British adults between the ages of 38 and 73 completed health questionnaires, underwent physical examinations and provided biological samples. The researchers asked each person about their drinking habits, tobacco and coffee consumption, including the number of cups they consumed each day. The doctors were also interested in the type of coffee people consumed, either decaffeinated, ground or instant.

Around 14,200 subjects died during the investigation

During the ten-year follow-up period, around 14,200 of the participants died, but the researchers found that people who consumed more coffee lived longer. The study found that participants who drank eight or more cups a day reduced their mortality rate by 14 percent. However, if the subjects drank six to seven cups of coffee a day, the risk of dying earlier was reduced by 16 percent.

Even small amounts of coffee lead to a longer life

Health benefits were also associated with lower coffee consumption, but to a lesser extent, the scientists explain. Two to five cups reduced the risk of premature death by twelve percent, while consuming just one cup or less than one cup a day reduced the risk of eight or six percent.

Drinking coffee can be part of a healthy diet

The consumption of coffee reduces the risk of premature death. This also applies to people with a slower or faster metabolism of caffeine, the researchers say. These results demonstrate the importance of ingredients in coffee to reduce mortality risk that have nothing to do with caffeine. They also confirm that drinking coffee can be part of a healthy diet, the doctors explain.

Coffee protects the heart

The new study follows a study recently published in the journal PLOS Biology, which has already linked caffeine consumption to an improved heart rate. Researchers at Heinrich Heine University and the IUF Leibniz Research Institute for Environmental Medicine in Düsseldorf have found that consuming four cups of coffee a day can help protect cardiovascular cells from damage and even help them repair them . The researchers concluded that drinking coffee or other caffeinated beverages could be particularly beneficial for the elderly because they are at greater risk of heart problems and heart disease than younger people.

Does coffee consumption increase anxiety?

Many people believe that coffee can increase nervousness and anxiety. In fact, scientists have been able to prove that certain types of coffee (such as mocha) can even reduce anxiety. According to scientists from Clarkson University in New York and the University of Georgia, this is due to the addition of cocoa (mixed roasts), which helps to reduce the anxiety-causing effects of caffeine.
