The results of the new study will delight coffee lovers

A new study shows that coffee, even if you drink more than eight cups a day, is badociated with a lower risk of death over a 10-year period. However, the researchers point out that the study found that the links between coffee and a longer life, which have not yet proved that coffee has a longer shelf life [19659002"Althoughthisdiscoverymayencouragecoffeelovers"-ErikkaLoftfieldoftheUSNationalCancerInstitute(NCI)theprincipalinvestigatorsaysthestudy

In a study published in Jama Internal Medicine on July 2, E. Loftfield and his team badyzed nearly 500,000 people involved in British Biobank. "Study data." More than nine million people were sampled in this project.

Part of the Biobank study included a survey of people on the number of cups of coffee that were used. they cooked all day long, including low-caffeinated coffee or caffeine-free coffee, and participants also answered the question about their overall health, education, smoking and drinking habits. The investigators took additional DNA samples.

Over 10 years of follow-up research, about 14,000 people died.The leading causes of death were cancer, cardiovascular disease The researchers noticed that the most consumed coffee drinkers were dying.Although there are differences between the types of coffee, the results of decaffeinated coffee and foods no n caffeinated are not significantly different from those of the drinkers.

According to E. Loftfield, the non-caffeine interconnection with longevity shows that many other constituents of coffee are affected. Caffeine alone. "

By badyzing participants' genetic data, scientists identified four genetic changes that were known to be related to caffeine metabolism – the way the body breaks down caffeine.Some previous studies have shown that people with these genetic changes are more at risk of cardiovascular disease, explains E. Loftfield

However, in a new study, researchers have found no connection between these changes and the risk of death

The fact that coffee can be healthy is not new.For example, the 2015 US Advisory Committee on Nutrition said that a light coffee beverage could make part of a healthy diet.However, the new study suggests that higher levels of coffee can be beneficial to health.

However, this does not mean that people should suddenly significantly increase the amount of coffee to drink: there is not enough data to change the dietary guidelines. Only a fraction of the people who participated in the study said that they ate up to eight or more cups of coffee a day – about 10,000 out of a total of 500,000 participants.

Harvard TH Professor Edward Giovannucci, Professor of Nutrition and Epidemiology at the Chan School of Public Health, said, "The new study is consistent with the previous one and suggests that the potential benefits of Increased coffee consumption is increasing, but that does not mean that everyone has to eat eight cups of coffee a day. "

E. According to Giovannucci, the investigators did not have enough coffee drinkers. During the follow-up period, the risk of death for people who eat about four cups of coffee a day was slightly higher than that of eight cups.

Although many studies on the peculiarities of coffee have been carried out, coffee to drink healthy. It is difficult to define causality because, according to E. Giovannucci, "the data come from observational studies in which people themselves declare how much coffee they drink". Nevertheless, there is ample evidence of the lower risk of various consequences, including overall mortality.

"The evidence may not be strong enough to recommend people to drink coffee because of their health benefits. However, people who love coffee can master themselves and know that they do not hurt and can even be beneficial. Do not double sugar and cream, "says E. Giovannucci
