Drinking more than six cups of coffee a day can be harmful to health, said scientists at the University of South Australia.

In a study published in The American Journal of Clinical Nutrition, researchers examined 350,000 people aged 37 to 73 years and concluded that drinking six or more cups of coffee daily increases the risk of heart disease to 22 %, moreover, a person becomes nervous, the load on the heart grows and the risk of stroke or heart attack increases. By the way, moderate coffee consumption has a positive effect on the body.

Cardiologist from Germany claims that, contrary to popular belief, coffee does not pose a threat to heart health and does not increase pressure if consumed regularly. Caffeine can reduce the risk of cancer, dementia, and diabetes. According to him, you can drink up to 4 cups of coffee per day.
