Coffee and longevity study may give you power

A new study offers more good news for coffee lovers. Drinking coffee is associated with a lower risk of premature death – regardless of whether you drink, caffeine, or not, concludes a study published Monday at JAMA Internal Medicine.

“We observed an adverse relationship to coffee with mortality, including among those who reported drinking at least one glass a day, up to eight or more cups per day, and drinking filtered, instant coffee and caffeine.

The researchers used data from the British biobank study, in which a large group of adults in the UK completed health questionnaires, underwent medical tests and provided biological samples. For the current study, the researchers analyzed the information provided by about 500,000 people who answered questions about coffee consumption, smoking and drinking habits, health history, and more. During the 10-year follow-up period, about 14,200 of these people died.

The researchers found the benefits of longevity linked almost with each level and type of coffee consumption. The risk varies slightly depending on the amount of coffee consumed by the person, its content of caffeine, and whether it is immediate or ground. But overall, for non-drinkers, those who ate a cup of coffee per day had an 8 percent lower risk of early death – a rate that rose slightly with increased consumption, reaching 16 percent when drinking six to seven cups a day, before Dipping a little, to 14%, for those who eat eight or more cups every day.

The speed of a person’s induction of caffeine does not seem to affect longevity, despite previous research suggesting that coffee may be associated with an increased risk of high blood pressure and heart attacks among people who slowly metabolize caffeine. But these studies looked only at drinking coffee after the disease and did not study the overall risk of death, as the current paper did. The use of the Biobank study allowed researchers to examine a huge amount of genetic data, including those related to caffeine metabolism, allowing for a more robust analysis.

combined with the effect of decaffeinated coffee over life, suggests that caffeine is not the mechanism of prolonging life in Java. But since the current study was controlled, meaning that it only addresses patterns in an existing data set, it is impossible to say what it is – or even if the coffee is really responsible for keeping death away or only associated with a longer life.

“Our current understanding of coffee and health depends primarily on the results of observational studies,” said Loftfeld. “In order to better understand the biological mechanisms underlying the binding of coffee with different health outcomes, additional studies are needed.”

However, the Loftfield study joins a large group that found health benefits associated with coffee. Although some previous studies linked coffee and other hot drinks to cancer, the World Health Organization (WHO) concluded last month that there was insufficient evidence to call coffee a carcinogen.

“Our study provides additional evidence that drinking coffee can be part of a healthy diet and offers reassurance to coffee drinkers,” said Loftfield.

A new study found that drinking coffee, even more than 8 cups per day, was associated with a reduced risk of death during a follow-up period of 10 years. However, the researchers found that the study found only a relationship with coffee and longevity and did not prove that coffee leads to longer life.

“Although these results may be reassuring to coffee drinkers, these findings are from a note-based study and should be interpreted with caution,” says Erica Loftvitt, a research fellow at the National Cancer Institute.

In the study, published today (July 2) in JAMA Internal Medicine, Loftfield and her team at the American National Institute analyzed data from about 500,000 people who participated in the UB.K study. Biobank. This project has collected health information from more than 9 million people. [10 things you need to know about coffee]

As part of the Biobank study, people were asked about the number of cups of coffee they consume daily, including decaffeinated coffee. Participants also answered questions about public health, education, and smoking and drinking habits. The researchers also took a DNA sample of the subject.

In a follow-up period of 10 years, about 14,000 people died in the study (the main causes of death were cancer, cardiovascular disease, and respiratory diseases). The researchers found that the more cups of coffee, the less likely to die during the study period. Although there are slight differences between the types of coffee people drink, the results were correct for instant coffee, ground and decaffeinated corticosteroids.

“It suggests that many other compounds in coffee, along with caffeine, may be responsible,” she told Loftefield Life Sciences.

When researchers looked at genetic data for participants, they identified four differences in genes known to be related to caffeine metabolism, or how the body breaks caffeine. Some previous studies have suggested that people with these genetic differences may be more likely to develop cardiovascular disease.

But in the new study, researchers found no association between the presence of these differences and the risk of death during the study period.

Enough coffee or a lot?
Not necessarily the news that coffee can be healthy; for example, the American Food Policy Advisory Committee of 2015 reported that moderate drinking coffee can be part of a healthy diet. But the new study suggests that larger amounts of coffee can be beneficial.

This does not mean that people have to eat large amounts of coffee, though: there is not enough data to change the guidelines to include more coffee, says Loftfield. In fact, only a small percentage of the people surveyed reported eating eight or more cups of coffee per day, and added – about 10,000 of the 500,000 participants.

Edward Giovanuci, Professor of Nutrition and Epidemiology at Harvard University T.H. Approved Chan School of Public Health, which was not part of the study. “This new study is consistent with previous studies but shows that the potential benefit extends to more coffee, but that does not mean everyone should drink 8 cups of coffee a day,” he said. ”

Giovannucci said the study does not have enough data from people who drink this amount of coffee. The risk of dying during the follow-up period was only slightly higher for people who drank about 4 cups of coffee a day compared to those who drank more than 8, said Life’s Science. Therefore, the benefit may be drinking more than 8 cups of coffee in about 4 small.

There are many studies that show about coffee, yet it is still difficult for researchers to come to a consensus on whether the drink is good for our health. It is difficult to conclude the causal relationship, because “the best data available to us are [observational] studies where people self-report [the amount of coffee they eat],” says Giovanuci. “However, the very large set of evidence [fixed] low risk for many of the results, including the overall mortality rate, is reassuring.

“While the evidence may not be strong enough to suggest that [anyone starts] drinking coffee for health benefits, people who drink coffee should feel reassured that there is no harm or even the benefits of coffee,” Giovanouchi said. But do not overdo the sugar and cream.
