Coffee lovers may no longer feel guilty when another cup of joy in this scented life arrives.
A new study suggests that coffee, even if you drink more than eight cups a day, is badociated with Risk of death for a period of 10 years. However, researchers point out that the study found that the links between coffee and longevity, which have not yet proved that coffee has a longer shelf life
" Although this discovery may encourage coffee lovers, "said Erik Loftfield of the US National Cancer Institute (NCI), lead author of the study. E. Loftfield and his team are badyzing data from nearly 500,000 people involved in the British Biobank study in a study published on July 2 in a magazine published by JAMA Internal Medicine.
Data from more than nine million people were collected. Part of the Biobank study included a survey of people on the number of cups of coffee they drink per day, including low-caffeinated coffee or caffeine-free coffee. Participants also answered the question about their overall health, education, smoking habits and alcohol consumption patterns.
The researchers then took DNA samples. During the 10 years of the follow-up study, approximately 14,000 people died there. The leading causes of death were cancer, cardiovascular and respiratory diseases. The researchers noticed that the most consumed coffee drinkers were dying. Although there were differences between types of coffee, the results of soluble and juicy coffee and non-caffeinated coffee products were not significantly different. According to E. Loftfield, the non-caffeine interconnection with sustainability "shows that many other constituents of coffee, not just caffeine, are affected"
By badyzing participants' genetic data, scientists have identified four genetic changes the metabolism of caffeine – the way the body breaks down caffeine. Some previous studies have shown that people with these genetic changes are at higher risk for cardiovascular disease, says Loftfield. But in a new study, researchers have found no connection between these changes and the risk of death
Enough or too much coffee?
The fact that coffee can be healthy can not be new. For example, the 2015 US Advisory Committee on Nutrition said that a light coffee beverage could be part of a healthy diet. But the new study suggests that higher levels of coffee can be beneficial for health. However, this does not mean that people should suddenly 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 eating up to eight cups of coffee a day. Harvard University Harvard TH Students' Center Professor Edward Giovannucci, Professor of Nutrition and Epidemiology at the Chan School of Public Health, said: "The new study is consistent with the previous and suggests that the potential benefits of increased coffee consumption increase, but that does not mean that everyone needs 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 those who ate about four cups of coffee a day was slightly higher than those who ate eight. Although many studies on the peculiarities of coffee have been conducted, it is still difficult for scientists to reach a consensus on the question of whether to drink healthy coffee
. However, there is ample evidence of a lower risk of various consequences, including overall mortality. "The evidence may not be strong enough to recommend people to drink coffee in 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. Just do not multiply the sugar and cream, "says E. Giovannucci
