A new study refutes previous research by suggesting that coffee drinkers are not at higher risk for chronic illnesses including heart disease and cancer than non coffee drinkers.
The study, which followed the exercise and diet habits of more than 42,000 German adults over the course of nine years, also suggested that coffee drinkers are less susceptible to developing type 2 diabetes.
“There have been conflicting results from previous studies regarding coffee’s effect on chronic disease risk depending on the type of disease,” said Anna Floegel, an epidemiologist at the German Institute of Human Nutrition Potsdam-Rehbruecke who helped lead the study. “That is why we decided to look at different diseases at the same time to estimate the overall health effect of coffee consumption.”
According to the study, which was published in the American Journal of Clinical Nutrition, 871 out of 8,689 non coffee drinkers developed some chronic disease, compared to 1,124 out of 12,137 people who drank more than four cups of caffeinated coffee a day. That’s about 10 percent of the population in each group.
“Our results suggest that coffee consumption is not harmful for healthy adults in respect of risk of major chronic diseases,” Floegel recently told Reuters.
