Research shows higher coffee consumption decreases the risk of death
Higher coffee consumption decreases the risk of death, shows evidence in several pieces of research. Coffee can be part of a healthy diet in healthy people.
The study, presented at the European Society of Cardiology Congress on 28 August 2017, examined the link between coffee consumption and the risk of mortality in a group of almost 20,000 middle-aged adults from the Mediterranean region within the time span of 10 years. The researchers used proportional hazards models to estimate hazard ratios and 95% confidence intervals for incident mortality.
Participants who consumed at least 4 cups of coffee a day had a 64% lower risk of all-cause mortality than those who did not consume coffee or did so very rarely. There was a 22% lower risk of mortality for each 2 additional cups of coffee daily. During the research period, 337 participants died.
The researchers found a significant link between coffee consumption and age. In those who were at least 45 years old, drinking two additional cups of coffee per day meant a 30% lower risk of mortality. The association was not confirmed among younger people.
Lower mortality among African-Americans, Japanese-Americans, Latinos, and whites was confirmed for the first time by a University of Southern California study. Until now, few data have been available for nonwhites. The research found the benefits of the coffee were not related to the caffeine, said Veronica Setiawan, an associate professor of preventive medicine at the Keck School of Medicine of USC.
Two other studies, published in the Annals of Internal Medicine, have also confirmed that drinking coffee is beneficial to health. Mayo Clinic nutrition expert Dr. Donald Hensrud admits there are side effects from drinking coffee that may limit its consumption, such as insomnia; gastroesophageal reflux disease; urinary problems; nervousness and anxiety, etc. These two studies, however, as well as numerous others, prove coffee’s health benefits. There is evidence that coffee reduced risk of liver disease and liver cancer, Parkinson’s disease, Type 2 diabetes, and even improves mood and depression. Thus, there is little reason to decrease consumption of coffee if people have no side effects.
