5 Proven Health Benefits of Drinking Coffee

By Muk Eun Ji / last month

Your daily coffee habit is helping you stay healthy, lowering your risks for developing several debilitating and potentially deadly diseases. Coffee is packed with biologically active compounds like polyphenols that help prevent the development of certain diseases. Here are five confirmed health benefits of regularly drinking coffee.

Lowers Your Risk for Diabetes

The caffeine found in coffee has been discovered to prevent diabetes. The findings of a study published in a 2010 issue of the Journal of Agricultural and Food Chemistry demonstrated that coffee contained anti-diabetic substances--the most effective of which was caffeine--that enhanced insulin sensitivity and hindered blood sugar increase.

In a separate study conducted by researchers from the Institute for Scientific Information on Coffee (ISIC), it has been found that the daily consumption of three to four cups of coffee may aid in preventing type 2 diabetes. This level of coffee consumption is associated with roughly 25 percent lower risk for type 2 diabetes, compared to drinking none or less than two cups of coffee per day.

Lowers Your Risk for Oral Cancers

If your intake of caffeinated coffee is more than four cups per day, then you approximately halved your risk of death from potentially fatal cancers such as oral and pharyngeal cancers. This is according to the results of an American Cancer Society study published in a 2012 issue of the American Journal of Epidemiology.

Lowers Your Risk for Liver Cancer

If you're a long-time coffee drinker, here's another reason to rejoice. Your three-cups-per-day coffee habit has helped curb by more than 50 percent your risk for developing liver cancer. This finding is based on a study published in a 2013 issue of the journal Clinical Gastroenterology and Hepatology.

Lowers Your Risk for Deadly Prostate Cancer

In May 2011, the online version of the Journal of the National Cancer Institute published the results of a study that correlates regular coffee drinking and decreased risk of developing the most harmful form of prostate cancer. Led by scientists from the Harvard School of Public Health, the study uncovered that men who drank six or more cups per day of either caffeinated or decaffeinated coffee had almost a 20 percent lower risk for any type of prostate cancer. In addition, the men who consumed six or more cups of coffee per day were 60 percent less likely to develop the lethal form of prostate cancer.

Live Longer

If you need only one reason to drink coffee, then this should be it--it lowers the overall risk of death. Published in the May 2012 issue of the New England Journal of Medicine, a large-scale study of older adults analyzed those who drank coffee--either caffeinated or decaffeinated--and those who were not coffee drinkers. Corrections were then made to account for the effects of mortality risk factors like alcohol consumption and smoking. Interestingly, the researchers discovered that coffee-drinking older adults were less likely to die from diabetes, heart disease, infections, injuries and accidents, respiratory ailment, and stroke. Compared to those who weren't coffee drinkers, the older adults who drank three or more cups of coffee daily had an estimated 10 percent reduced risk of death.
