Coffee is increasingly earning scientists’ approval. Studies continue to suggest that the beverage may have some beneficial effects on health.
In the latest analysis, published in the BMJ, researchers scanned nearly 220 studies on coffee and found that overall, coffee drinkers may enjoy more health benefits than people who don’t drink the brew.
The scientists, led by Robin Poole from the University of Southampton in the UK, learned that people who drank coffee were 17% less likely to die early during the study period from any cause, 19% less likely to die of heart disease and 18% less likely to develop cancer, compared to people who did not drink coffee.
Other recent studies have linked coffee drinking to lower rates of heart disease, early death and diseases like liver cirrhosis,type 2 diabetes and even neurological conditions like Parkinson’s and Alzheimer's disease. Poole’s group found that the strongest benefit occurred among people who drank around three cups of coffee a day.
“I think now we can be reasonably reassured that overall, coffee drinking is a safe habit,” says Dr. Eliseo Guallar, professor of epidemiology and medicine at Johns Hopkins Bloomberg School of Public Health, who wrote an editorial accompanying the study.
