Drinking 3 to 5 cups of coffee a day could reduce the risk of premature death from conditions such as cardiovascular disease, type 2 diabetes, and neurological diseases according to researchers from Harvard T.H. Chan School of Public Health.
Researchers analysed health data gathered from participants in three large ongoing studies of nurses and health professionals over 30 years. Drinking coffee was associated with reduced risk of death from cardiovascular disease, diabetes, neurological diseases such as Parkinson’s disease, and suicide but was not associated with cancer deaths. The analyses took into consideration factors such as smoking, body mass index, physical activity, alcohol consumption, and diet. Decaffeinated coffee was also found to reduce risk.
Lead author of the paper Ming Ding said, “Bioactive compounds in coffee reduce insulin resistance and systematic inflammation.”
“This study provides further evidence that moderate consumption of coffee may confer health benefits in terms of reducing premature death due to several diseases,” said senior author Frank Hu, professor of nutrition and epidemiology. “These data support the 2015 Dietary Guidelines Advisory Report that concluded that ‘moderate coffee consumption can be incorporated into a healthy dietary pattern.’”
