Does drinking too much coffee lengthen life?

Those who drink coffee should not feel guilty: it is more beneficial to one's health than one might think.

A study suggests that drinking coffee, even more than 8 wells per day, is badociated with lower risk. of death, but … the researchers pointed out that the study found an badociation between coffee and longevity, and not that it proved that this drink leads to a longer life.

Results should be taken with caution, said study director, Erikka Loftfield

In research, published in Jama Internal Medicine, Loftfield and his group badyzed data from nearly 500,000 people of Biobank in the UK.

Participants were asked how much coffee they had, including decaffeinated questions, and also answered their questions about their health, education, and alcohol and cigarette consumption patterns. In addition, their DNA was badyzed.

During the 10 years of follow-up, approximately 14,000 died, mainly from cancer, cardiovascular disease and respiratory problems. It was found that the higher the ingested coffee rates, the less people would die during the 10 years of the study, solid results for any type of coffee, suggesting that other compounds of caffeine in the grain could be responsible for longevity.

By badyzing genetic information, known genetic variants for their badociation with caffeine metabolism or the way the body breaks it down have been identified. Some studies have suggested that people with these variants may have an increased risk of cardiovascular disease.

In the new study, no connection was found between the existence of these variants and the risk of death during the period of investigation

. US Dietetic 2015, reports, for example, that moderate coffee consumption can be part of a healthy diet. The new contribution is that even larger quantities can be beneficial, which does not mean that it is often recommended to increase coffee because only a fraction of those polled said they had drunk more than 8 Wells per day, about 10,000 In addition, the differences in longevity between those who ingested 4 wells and 8 wells are not very significant.

And although there is no convincing evidence to recommend anyone who starts drinking coffee for his health, those who do it may know that it does not hurt and probably benefits from it.
