If you’re brewing your 7th cup of coffee for the day, you may want to turn off the machine.
A new study, published in The American Journal of Clinical Nutrition, suggests drinking over six cups of coffee a day negatively impacts the body. According to the research, too much coffee can lead to a 22 per cent increased risk of heart disease.
The World Health Organization recognizes heart disease as one of the leading causes of death around the world, despite it being one of the most preventable conditions.
The researchers say the study confirms excess caffeine contributes to cardiovascular disease, such as a high blood pressure.
“Most people would agree that if you drink a lot of coffee, you might feel jittery, irritable or perhaps even nauseas – that’s because caffeine helps your body work faster and harder, but it is also likely to suggest that you may have reached your limit for the time being,” Elina Hyppönen, a researcher at the University of South Australia, said in a statement.
She went on to say that a health heart and blood pressure can be maintained if coffee is limited to under six cups a day.
The findings come from the analysis of data from the UK Biobank, which included 347,077 participants aged 37 to 73 years old. Researchers analyzed how the caffeine-metabolizing gene, called CYP1A2, processes caffeine in the body.
Hyppönen does note that the research does not support the theory that some people can safely consume over six cups or more frequently, and be resistant to adverse health effects.
“An estimated three billion cups of coffee are enjoyed every day around the world,” the researcher said. “Knowing the limits of what’s good for you and what’s not is imperative. As with many things, it’s all about moderation; overindulge and your health will pay for it.”
