The research showed that, with parity in relevant factors such as age, coffee consumption is usually significantly associated with lower mortality. The effect was also observed in caffeine and coffee without caffeine; and soluble and machined.

According to study data, published in the American Journal of Clinical Nutrition, protection was most potent in people aged 55 years and older and showed a clear dose-response trend in the range of 1 to 6 cups a day.
Adela Navara, a cardiologist at the health care system Navara and author of the study, says it is already known that these assumed risks of high blood pressure do not exist in the long run. "We now find clear benefits for the risk of mortality for all reasons, which supports the benefits of their consumption."
Estefania Toledo, a professor at the University of Navarre and director of the work, says the results point in the same direction as those of the other recent cohorts and have used rigorous methods to assess the effect of coffee, such as the EPIC or EUREYE study. -Spain
But the new aspect of the new research is that the benefits were sustained even by consuming 4-6 cups of coffee per day and were particularly present in the elderly, where mortality was mainly caused by chronic illness.
More coffee, lower mortality?
So, the better it is to control possible alternative explanations of the cause, the clearer the reverse association is, the more it is clear: the more coffee, the lower the total mortality.

According to the authors, "There is no risk that the study will be affected by the problem of sick ex-consumers, that is, those who leave coffee, because they already have a previous illness.
For experts, the benefits can not be explained by one component, since coffee "It is a complex mixture of substances and there are many antioxidant and anti-inflammatory properties among them, and it is logical to think that they are acting in synergy".
"When we are committed to a healthy diet or habits, it seems that we take people away from everything they like. There are many people who love coffee. These data are solid and are already known for sure, concludes Miguel A. Martinez-Gonzalez, another of the authors.
