Although large amounts of coffee are not good for the stomach and can lead to insomnia, scientists have new evidence that our favorite black beverage is actually very healthy and it protects us from many diseases.
Scientists say that people who drink 3 to 4 cups of coffee a day, have lower risk of premature death due to heart disease, diabetes and Parkinson’s disease and are less prone to depressive state and suicide.
The study was conducted at the Harvard Department of Public Health and covered people who either drank no coffee at all or consumed less than two cups a day. Then the results were compared with the results of those who drank moderate amounts of this beverage, as well as those drinking up to five cups a day.
– “Bioactive ingredients in coffee reduce insulin resistance and prevent the development of inflammatory processes in the body”, said Ding Ming, the lead author of the study*.
The survey results are based on data collected from three major surveys conducted among 300,000 nurses and health workers, who during 30 years regularly filled out questionnaires about their health and lifestyle.
– “Only healthy people who adhere to a healthy lifestyle should drink more coffee. Pregnant women, nursing mothers, people with high blood pressure and young people should be aware of how much caffeine they consume and we should not consume caffeine excessively” – says Frank Hu, co-author of the study, who teaches nutrition and epidemiology at Harvard.
