There is no shortage of studies that emphasize how coffee is beneficial to your health. The latest study to be published about coffee and health draws a direct line between drinking coffee and reducing the risk of early death.
The study was published in Circulation, a journal from the American Heart Association. Its researchers are from the Department of Nutrition at the Harvard School of Public Health, and they began by surveying adults in the United States to determine what they ate and drank. The researchers also looked at rates of disease and death among the respondents over the next two decades.
The large study followed more than 50,000 men and 200,000 women. There was not much of a relationship between drinking coffee and death rates at first look. The risk of dying was only about five to nine percent lower in respondents who drank less than one to three cups of coffee per day when compared to those who drank no coffee. Respondents who drank more coffee had no added benefit.
Looking at the results of those who drank coffee and did not smoke showed a much clearer result. When looking at these numbers, the researchers determined that those who drank three to five cups or more of coffee per day had 12 and 15 percent lower death rates. Coffee drinkers were 10 percent less likely to die of heart disease and up to 37 percent less likely to die of neurological diseases.
One of the doctoral students involved in the study suggests that this link is due to coffee consumption being tied to a lower risk of heart disease and type 2 diabetes. The researchers took into account other dietary factors, leading them to believe that the health benefits of coffee are likely due to some of its ingredients, like chemicals that can help to control blood sugar.
