People who regularly drink coffee will live longer than those who don’t. And those who drink a lot of coffee live longer than those who drink less coffee. That’s what scientists at the National Cancer Institute, the National Institutes of Health and Feinberg School of Medicine at Northwestern University observed, when analyzing data from the Biobank health project.
Biobank is a long-term research project in the UK. They collect health data for more than half a million people to find ways to improve the prevention, diagnosis, and treatment of a range of serious and life-threatening illnesses – including cancer, heart disease, stroke, diabetes, depression and dementia …
Because Biobank is a large sample, the data from it will give a greater reliability and accuracy than most other scientific studies using small samples. It is possible that people who drink coffee are often people who are aware of the importance of lifestyle, so they also exercise more or eat more nutrition.
The results published in the scientific journal JAMA Internal Medicine show a correlation on people’s health and coffee drinking habits. To be clear, scientists do not claim that it is a causal relationship. That is, drinking a lot of coffee is not necessarily the main factor to help them live healthier and longer.
Drinking more coffee helps you live longer, if it is a cause-and-effect relationship, will be great news for many people who are even worried that they drink too much coffee. So how much is enough?
The benefits of coffee exist even if you drink up to 8 glasses a day, equivalent to half a gallon or 1.9 liters. But most people can hardly drink that much. Usually only 2-3 cups of coffee make you drunk.
Fortunately, if you buy high quality coffee, store it properly and regularly clean your coffee maker, you won’t need any extra sugar. Coffee has a natural sweetness and drank much you will get used to it.
