Drinking More Than Six Cups of Coffee Daily Linked With Increased Risk of Cardiovascular Disease
Coffee contains a high level of antioxidants and may provide such benefits as increased energy from caffeine and improved physical performance. Too much coffee, however, may not be a good thing. According to a new study, drinking six or more cups of coffee per day may increase the risk of heart disease by up to 22%.
The researchers obtained information on habitual coffee intake for 347,077 individuals from the UK Biobank. They used logical regression to evaluate the association between coffee intake and cardiovascular disease risk.
They found that compared to participants who drank 1 to 2 cups of coffee per day, the risk of cardiovascular disease was increased by 11% for those who did not drink coffee, by 7% for those who drank decaffeinated coffee, and by 22% for those who drank more than six cups per day.
The study was conducted by researchers from the University of South Australia Cancer Research Institute. It was published March 6, 2019 in The American Journal of Clinical Nutrition.
